Hastelloy G30 (UNS N06030, W.Nr. 2.4603) is a high-chromium nickel alloy designed for wet-process phosphoric acid and strongly oxidising mixed acids. Specify it when oxidising acids, fluoride or chloride impurities, or as-welded corrosion resistance dominate the design; choose a higher-molybdenum C-type alloy instead when the service is mainly reducing, such as hot dilute hydrochloric or sulphuric acid.
Most corrosion-resistant alloys are a balance between two jobs. Chromium builds a thin, self-healing oxide film that protects against oxidising acids such as nitric acid and acid mixtures carrying ferric or cupric ions. Molybdenum and tungsten protect against reducing acids and against localised pitting under deposits. G30 pushes chromium to about 30% - roughly twice the chromium of Hastelloy C276 - while keeping 4-6% molybdenum, 1.5-4% tungsten and 1-2.4% copper.
Think of chromium as the shield and molybdenum as the back-up shield for the opposite kind of chemical attack. Copper further improves behaviour in phosphoric and sulphuric acid, and niobium ties up carbon so that welding does not drain chromium from the grain boundaries.
That last point is why the alloy is widely used in the as-welded condition. Ordinary stainless steels can lose corrosion resistance next to a weld because chromium carbides precipitate in the heat-affected zone. G30 limits carbon to 0.03% maximum and adds niobium as a stabiliser, so the heat-affected zone resists grain-boundary precipitation and many chemical-process components can enter service without post-weld heat treatment. Where cold forming exceeds about 7% outer-fiber elongation, however, re-annealing is still required - see the fabrication section below.
HASTELLOY and G-30 are registered trademarks of Haynes International. JN Alloy supplies material manufactured to UNS N06030 and the ASTM/ASME standards listed on this page. If your project requires mill material carrying the Haynes brand, state that explicitly in the enquiry so it can be sourced and priced separately.
G30 is the high-chromium member of the nickel-alloy family. It wins in wet-process phosphoric acid, nitric/hydrofluoric pickling mixtures and oxidising mixed acids. It is not the cheapest alloy and it is not the best choice for hot hydrochloric acid. Confirm the acid chemistry, temperature and impurity levels before you compare prices.
Hastelloy G30 Chemical Composition
A valid N06030 mill certificate must report chromium 28.0-31.5%, iron 13.0-17.0%, molybdenum 4.0-6.0%, tungsten 1.5-4.0%, copper 1.0-2.4%, Nb+Ta 0.30-1.50%, carbon 0.03% maximum and nickel as the balance. Every one of those ranges should appear as an actual measured heat value, not as a nominal or typical figure.
Grade | C≤ | Mn≤ | P≤ | S≤ | Si≤ | Cr | Mo | Fe | Co≤ | Cu | Nb+Ti | W | Ni |
G30 | 0.03 | 1.5 | 0.04 | 0.02 | 0.8 | 28.0--31.5 | 4.0--6.0 | 13.0-17.0 | 5.0 | 1.0--2.4 | 0.3--1.5 | 1.5--4.0 | Remainder |
Product analysis tolerances are covered by ASTM B880. If a certificate reports only a subset of these elements, ask for the full ladle analysis before the material is released for fabrication. For a side-by-side reading of the broader alloy family, see our Hastelloy steel grade hub and the nickel alloy range.

Which ASTM, ASME and DIN Standards Apply to Each G30 Product Form?
The standard follows the product form, not the trade name: plate, sheet and strip are ASTM B582 / ASME SB-582; seamless pipe and tube are B622 / SB-622; welded pipe and tube are B619 and B626; billet, rod and bar are B581 and B472; fittings are B366 and B462; forgings are B462. Always write the standard into the purchase order next to the form.
A mill certificate is only meaningful when it is tied to a product standard. B582, for example, defines the condition, tolerances, testing and certification for flat-rolled products, while B622 does the same for seamless tubular products. Ordering simply 'Hastelloy G30 pipe' leaves the weld seam, heat-treatment condition, dimensional tolerance and test regime undefined - the four things most likely to cause a dispute at goods-in. For pressure equipment, quote the ASME SB edition so the material is code-traceable, and state the ASME P-No. 45 grouping on the welding documentation.
The original table lists ASTM A619 for welded pipe and ASTM A462 for forgings / flanges. The A-series specifications cover steel products; the correct nickel-alloy designations are ASTM B619 (welded pipe), ASTM B626 (welded tube) and ASTM B462 (forged or rolled pipe flanges, forged fittings and valves). ASTM B622, B582, B581, B472, B366 and B462 in the original table are correct. The original table is preserved unchanged for traceability; use the corrected mapping below for all new enquiries and purchase orders.
Two further designations belong in a complete specification: DIN / Werkstoff 2.4603 (NiCr30FeMo) for European projects, and NACE MR0175 / ISO 15156 when the component is destined for sour oil and gas service. Sour service may require a hardness-controlled or cold-work-controlled condition, which must be agreed before production starts. Our nickel alloy pipe selection by acid type guide and the chemical-plant pipe selection guide explain how the standard follows the medium.
How Does G30 Compare With C276, C22, G35, Alloy 31 and 904L?
G30 is the oxidising-acid specialist. Choose it over C276 or C22 for wet-process phosphoric acid and nitric-based mixed acids; choose C276 for broadly reducing, chloride-rich service; choose G35 when fertiliser-grade phosphoric acid at high temperature is the single dominant duty; choose Alloy 31 or 904L only when a lower-cost, lower-alloy solution has been validated by corrosion testing against your actual liquor.
The difference is visible in the chemistry. G30 carries about 30% chromium and 4-6% molybdenum. C276 carries roughly 15-16% chromium and 15-17% molybdenum plus tungsten, which is why it tolerates hot reducing acids and chloride pitting so well. C22 sits between them for oxidising performance but is still a C-type alloy. G35 raises chromium to about 33% with around 8% molybdenum and very little copper or iron, targeting high-temperature fertiliser-grade P2O5 specifically. Alloy 31 and 904L are iron-based or lower-nickel options that work in clean acid but lose margin quickly once chlorides, fluorides or oxidising impurities appear.
Two cautions keep this comparison honest. First, these are design-intent comparisons, not corrosion-rate guarantees; the actual ranking can reverse at a specific concentration and temperature. Second, PREN (pitting-resistance equivalent number) is a useful screening tool for stainless and duplex grades but is not the controlling selection criterion for a high-chromium nickel alloy in oxidising acids. Ask for an iso-corrosion curve or a coupon test in your own liquor. For a fuller C-family comparison, see C22 vs C276 and the C276 ultimate guide.
In Which Acid Services Does G30 Actually Outperform Other Alloys?
G30 earns its specification in wet-process phosphoric acid, nitric/hydrofluoric and nitric/hydrochloric pickling mixtures, nitric acid recovery, and sulphuric acid carrying oxidising impurities. It is not the first choice for hot dilute hydrochloric acid or for strongly reducing sulphuric acid, where a high-molybdenum C-type alloy is safer.
Corrosion is a system property, not a number printed on a data sheet. In a phosphoric-acid evaporator the bulk liquor may look mild while the liquid boiling right at the tube wall is far more concentrated, and chloride-rich scale can create a crevice that is far more aggressive than the open surface. Producer iso-corrosion tables also show that hydrochloric-acid attack on G30 is non-monotonic: rates can jump sharply at some intermediate concentration-temperature combinations even though neighbouring points look benign.
This is why a responsible supplier asks for the full liquor analysis - acid concentration, temperature, chloride, fluoride, free sulphuric acid, oxidants and solids - before confirming a grade. Our C276 hydrochloric acid selection guide and the 316H / 98% sulphuric acid analysis show the same principle applied to other grades.
For plant-level context, see the chemical equipment market page, the nickel alloy pipe range and our prefabrication service for complete spools and welded assemblies.
Which G30 Product Forms and Sizes Can JN Alloy Supply?
JN Alloy can supply N06030 as plate, sheet and strip; seamless and welded pipe and tube; bar and rod; butt-weld and forged fittings; flanges and forgings; and completed prefabricated spools. Name the form and its governing ASTM standard in the enquiry and we will confirm available sizes and lead time against current mill stock.
Grouping the order by form avoids a common and expensive mistake: a single purchase order that mixes B582 plate, B622 tube and B462 flanges but cites only one standard. Each form has its own acceptance tests and certificate. Cutting plate to size, water-jet or plasma cutting, bevelling, bending and full-penetration welding can be completed in-house, but every thermal or cold-forming step must be recorded so the required re-anneal is not missed.
What Must a Hastelloy G30 RFQ State Explicitly?
A usable RFQ states twelve things in writing: grade and UNS number, product form, governing ASTM/ASME standard, dimensions and tolerances, quantity, supply condition, full process chemistry, design temperature and pressure, required certification, inspection and NDE, packing and marking, and delivery terms. Missing any one of them turns a quotation into a guess.
Most price disputes on nickel alloys are not about the alloy - they are about an undefined condition. A quote for 'G30 plate' might assume hot-rolled, as-cut material with a basic certificate of compliance, while the buyer expects solution-annealed, pickled, cut-to-size plate with EN 10204 3.1 and a witnessed intergranular-corrosion test. The twelve lines above cost five minutes to fill in and remove that gap. Send the completed checklist to the JN Alloy technical team for a dated written quotation.
Next step: Attach your liquor analysis and isometric drawing to the RFQ. If you do not have a full analysis yet, tell us the acid, concentration, temperature and known impurities and we will list the additional data needed before confirming the grade.
How Should G30 Be Welded and Heat Treated?
Weld G30 by GTAW/TIG, GMAW/MIG or SMAW with matching filler ERNiCrMo-11 (bare wire) or ENiCrMo-11 (coated electrode), and solution anneal at 1177 C (2150 F) for 10-30 minutes followed by water quenching. Re-anneal after any hot forming and after cold forming that produces 7% or more outer-fiber elongation. Do not use submerged-arc welding.
G30 is more sensitive to strain and strain rate than 304 or 316L. It work-hardens quickly, needs more energy to form, and may require several cold-forming stages with intermediate anneals. Cold work does not usually harm general corrosion or pitting resistance, but it can reduce resistance to stress-corrosion cracking - the exact failure mode that matters in a hot chloride-bearing evaporator. The re-anneal is therefore not a courtesy step; it is the step that restores the property you bought the alloy for.
Welded fabrications that will be pickled or placed in nitric/HF service should also have the weld root and heat-affected zone included in the corrosion-test coupon plan. Ask for the WPS, PQR and filler lot numbers as part of the documentation package.
What Does Hastelloy G30 Cost and What Drives the Price?
There is no honest fixed price per kilogram for G30. A valid quotation is dated and reflects the current nickel, molybdenum and tungsten surcharges, product form, size, condition, testing scope and quantity. Ask for a dated quote with the surcharge basis stated rather than comparing an undated number from a web page.
Price noteThis page intentionally publishes no numerical price band. Nickel-alloy prices move with the metal markets and any undated figure would be misleading. Figures in older articles, including the 2025 G30 bar price article, are historical commentary and are not a quotation. Price information on this page reviewed 6 November 2026; request a dated written quotation from JN Alloy before budgeting.
Two suppliers can quote very different numbers for the same UNS designation because one includes the anneal, 3.1 certificate, PMI and export packing while the other does not. Comparing those numbers without a scope checklist is how projects end up with material that passes on paper and fails at goods-in. For wider context see our markets page and the full product catalogue.
How Do You Verify a G30 Supplier Before Placing an Order?
Verify five things before you pay: that the supplier can name the governing ASTM/ASME standard for each form, produce a sample EN 10204 3.1 certificate with a full heat analysis, show its WPS/PQR for P-No. 45, demonstrate PT and PMI capability, and keep heat traceability through cutting and fabrication. A seller who cannot answer these is trading metal, not engineering material.
Ask for a sample certificate. Check that Cr, Mo, W, Cu, Nb+Ta and C are all reported with measured values, not only 'meets specification'.
Ask which standard applies to each form. B582 plate, B622 seamless tube, B619/B626 welded tube, B581/B472 bar, B366/B462 fittings, B462 forgings.
Ask about the anneal. Confirm 1177 C solution annealing, the quench method and the re-anneal rule after >=7% cold-forming strain.
Ask for the WPS and PQR. Base metal P-No. 45 and filler F-No. 45 with ERNiCrMo-11 / ENiCrMo-11.
Confirm NDE capability. PT rather than MT, plus UT/RT where required; ask who signs the reports.
Confirm PMI and traceability. Heat number must survive cutting, bending and welding and appear on the final marking.
Check fabrication and packing. Protected faces, no carbon-steel contact, sealed export packing with documentation.
Check the commercial frame. Incoterm, validity period, surcharge basis, lead time and the name of the technical contact who will answer questions after the order.
These questions separate a mill-direct or technically capable stockist from a pure trader. They are also the same questions an EPC contractor's inspector will ask at goods-in, so answering them early avoids a rejection that is far more expensive than the extra certificate. Read more about our capabilities on the about us page, the prefabrication service page and in the JN Alloy news and technical library.
Which Applications Use G30 Components Most Often?
G30 is most often specified for wet-process phosphoric acid evaporators and heat exchangers, nitric/HF pickling equipment, nitric acid and nuclear reprocessing plant, sulphuric and mixed-acid vessels, and acidic waste or hydrometallurgical circuits. In every case the common factor is an oxidising acid carrying halide impurities.
Look at the list below and the same chemistry repeats. Each duty combines a high oxidation potential with fluoride, chloride or both - exactly the conditions where a high-chromium passive film is needed and where stainless steels lose their margin. That is why a single alloy appears in fertiliser plants, steel pickling lines and nuclear reprocessing, three industries that otherwise share almost nothing. It also explains the exceptions: a plain reducing acid stream with no oxidants and no halides does not need G30, and paying for it there adds cost without adding life.
The original application list published on this page is retained verbatim below:
Phosphoric acid equipment
Pickling operations
Sulphuric acid equipment
Petrochemical products
Nitric acid equipment
Fertilizer production
Nuclear fuel reprocessing
Pesticide production
Nuclear waste disposal
Gold extraction
For application-level reading, see the chemical equipment, oil and gas, water treatment and markets pages. If your service is reducing rather than oxidising, start with C276 or B2 instead.
How Should You Store and Handle G30 Before Fabrication?
Store G30 under cover, off the floor, separated from carbon steel, with original markings and protective wrapping intact until fabrication begins. Use dedicated stainless or nickel-alloy tools, avoid chloride-containing markers and adhesives, and clean the surface before any heat treatment or welding.
Keep it dry and covered. Rainwater pooling inside a pipe rack concentrates chlorides; store under a roof with positive drainage.
Separate from carbon steel. Dedicated racks, slings and fork tines prevent iron embedment and rust staining.
Keep identification attached. Do not remove the heat-number tag when cutting; transfer it to every offcut or record it in a cutting list.
Use low-chloride consumables. Markers, tapes, grinding wheels and cleaning solvents should be chloride-free and sulphur-free.
Clean before heating. Oil, grease and drawing compounds must be removed before annealing or welding to avoid carbon pick-up.
Protect machined faces. Flange facings and bevels remain capped or covered until fit-up.
Most 'alloy failures' reported before commissioning are actually handling damage: iron contamination, chloride residues or a lost heat number. Good housekeeping is the cheapest quality control available, and it protects the traceability that the EN 10204 certificate is meant to guarantee.

Key Takeaways
Hastelloy G30 is UNS N06030 / W.Nr. 2.4603: a ~30% chromium nickel alloy built for oxidising acids, not a general-purpose C-type alloy.
Its strongest case is wet-process phosphoric acid, nitric/HF pickling mixtures and other oxidising, halide-bearing mixed acids.
Low carbon (0.03% max) plus Nb+Ta (0.30-1.50%) is why many G30 components can be used as-welded.
Specified minimums are 586 MPa tensile, 241 MPa yield and 30% elongation, density 8.22 g/cm3 - design to minimums, not typical values.
The standard follows the form: B582 plate, B622 seamless tube, B619/B626 welded tube, B581/B472 bar, B366/B462 fittings, B462 forgings.
Solution anneal at 1177 C and re-anneal after cold forming with >=7% outer-fiber elongation; use ERNiCrMo-11 / ENiCrMo-11 filler.
Require EN 10204 3.1, PMI and PT (not MT, because G30 is non-ferromagnetic); add ASTM G28 and volumetric NDE where the service warrants it.
Never accept an undated price and never skip the liquor analysis - both are the two most common causes of a wrong material decision.
Frequently Asked Questions
What is Hastelloy G30?
Hastelloy G30 is a high-chromium nickel-chromium-iron-molybdenum-copper alloy designated UNS N06030 and W.Nr. 2.4603. It was developed for wet-process phosphoric acid and strongly oxidising mixed acids, and its low carbon and niobium content allow many components to be used in the as-welded condition.
Is Hastelloy G30 the same as Hastelloy G-3?
No. G-30 is an improved successor to G-3 with roughly 28-31.5% chromium instead of about 22%, plus controlled tungsten, copper and niobium. The higher chromium gives markedly better resistance to commercial phosphoric acid and oxidising mixed acids; the two grades are not interchangeable.
What is the UNS number and DIN number for G30?
The UNS designation is N06030 and the Werkstoff number is 2.4603, with the DIN short name NiCr30FeMo. Welding consumables carry UNS N06030 (bare wire) and W06030 (coated electrodes).
Which ASTM standard covers Hastelloy G30 plate?
ASTM B582, with ASME SB-582 as the code counterpart, covers sheet, plate and strip. Seamless pipe and tube are B622/SB-622, welded pipe and tube B619 and B626, bar and billet B581 and B472, fittings B366 and B462, and forgings and flanges B462.
Why is G30 better than C276 in phosphoric acid?
Because phosphoric acid produced by the wet process is an oxidising, halide-bearing medium. G30's ~30% chromium builds a stronger passive film under those conditions, while C276's ~16% molybdenum is optimised for reducing acids and chloride pitting. In hot dilute hydrochloric acid the ranking reverses and C276 is the safer choice.
Can Hastelloy G30 be used in hydrochloric acid?
Only with care and usually not as the first choice. G30 has moderate resistance from its molybdenum and copper, but published producer data show steep corrosion-rate increases at certain intermediate HCl concentrations and temperatures. Never interpolate between two points on an iso-corrosion table; test the actual liquor or select a high-molybdenum C-type alloy.
Does G30 need post-weld heat treatment?
In most chemical-process applications, no: carbon is limited to 0.03% and niobium stabilises the alloy, so the heat-affected zone resists grain-boundary precipitation. Solution annealing is still required after hot forming and after cold forming that produces 7% or more outer-fiber elongation.
What filler metal is used to weld G30?
Matching composition filler: ERNiCrMo-11 bare wire or rod to AWS A5.14 / ASME SFA 5.14, and ENiCrMo-11 coated electrodes to AWS A5.11 / ASME SFA 5.11. GTAW, GMAW and SMAW are all suitable; submerged-arc welding is not recommended because of its high heat input and slow cooling.
What is the solution annealing temperature for G30?
1177 C (2150 F), held 10 to 30 minutes depending on section thickness, followed by water quenching. Rapid air cooling is acceptable for structures thinner than about 10 mm (0.375 in). This is a heat-treatment setpoint, not a melting point.
What is the density of Hastelloy G30?
8.22 g/cm3, equivalent to 0.297 lb/in3. This is the value published on the original JN Alloy property table and on producer data sheets; use it for weight estimation, not as an acceptance criterion.
What mechanical properties does G30 guarantee?
For solution-annealed material the commonly specified room-temperature minimums are 586 MPa (85 ksi) tensile strength, 241 MPa (35 ksi) 0.2% offset yield strength and 30% elongation. Actual values vary by product form and heat treatment, so use the mill test certificate for acceptance.
Is Hastelloy G30 magnetic?
No. It is a fully austenitic nickel alloy and is essentially non-ferromagnetic in the annealed condition. That is why liquid penetrant testing, not magnetic particle inspection, is the applicable surface NDE method.
Can G30 be used for flanges and fittings?
Yes. Forged or rolled flanges, forged fittings and valve parts are covered by ASTM B462 / ASME SB-462, and wrought fittings by ASTM B366 / ASME SB-366. State the class, facing, size, schedule and whether seamless or welded construction is required.
Which certificate should I request for G30 material?
EN 10204 3.1 as a minimum, issued by the manufacturer's independent inspection department with the full ladle analysis and mechanical test results. For nuclear, pressure-equipment or EPC projects, specify EN 10204 3.2 with third-party witnessing, plus PMI and NDE reports.
How does G30 differ from G35?
G35 (UNS N06035) raises chromium to about 33% and molybdenum to about 8% with very low iron and copper, targeting high-temperature fertiliser-grade phosphoric acid evaporators. G30 keeps 13-17% iron and 1-2.4% copper, which gives it broader mixed-acid versatility and wider product availability. Choose by the actual liquor, not by the higher chromium number.
Is G30 suitable for sulphuric acid service?
It is used in sulphuric acid equipment where oxidising impurities are present and concentrations are moderate, thanks to copper and molybdenum. For hot concentrated or strongly reducing sulphuric acid, other grades may be more economical or more resistant. Confirm with a corrosion coupon in your own acid.
What is the ASME P-number for G30?
P-No. 45 for the base metal, with F-No. 45 for the matching filler metal. Quote both on the WPS/PQR so welding procedure qualification under ASME Section IX is auditable.
Does G30 meet NACE MR0175 / ISO 15156?
The alloy is listed in producer specification tables for sour-service qualification, but compliance depends on the supplied condition, hardness and cold work. If the component is for sour oil and gas service, state NACE MR0175 / ISO 15156 on the enquiry so the condition and hardness limits are agreed before production.
What product forms can JN Alloy supply in G30?
Plate, sheet and strip; seamless and welded pipe and tube; bar and rod; butt-weld and forged fittings; flanges and forgings; and prefabricated spools or welded assemblies. Each form is quoted to its own ASTM/ASME standard with heat traceability.
How do I get a price for Hastelloy G30?
Send the grade, product form, standard, dimensions, quantity, supply condition, process chemistry, required certification and delivery terms to JN Alloy. Because nickel, molybdenum and tungsten surcharges move with the metal markets, we issue a dated written quotation with the surcharge basis stated rather than publishing an undated price band.
Why does the original table say ASTM A619 and ASTM A462?
Those are typographical errors on the original page. The A-series specifications cover steel products; the correct nickel-alloy standards are ASTM B619 for welded pipe and ASTM B462 for forgings and flanges, with B626 additionally covering welded tube. The original table is preserved unchanged on this page for traceability and the corrected mapping is published alongside it.
Is HASTELLOY a JN Alloy brand?
No. HASTELLOY and G-30 are registered trademarks of Haynes International. JN Alloy supplies material manufactured to the UNS N06030 designation and the relevant ASTM/ASME standards. If your project requires Haynes-branded mill material, state that requirement at enquiry stage so it can be sourced and priced separately.
