Supply Steel And Nickel Alloy Products
Stainless Steel
Material: AISI 316, UNS S31600, 1.4401/1.4436
316 stainless steel is created by adding molybdenum and nickel to 304 stainless steel, and belongs to the austenitic stainless steel series. 316 steel has a high temperature resistance of 1200-1300 degrees due to the addition of M0 element. Due to its excellent performance, 316 stainless steel pipes are widely used in medical device manufacturing, pharmaceutical and food industries, chemical industries and other fields.
Duplex & Super Duplex
Material: Grade S32760, DIN 1.4501, F55
Duplex steels S32760 and F55 are resistant to various inorganic and organic acids. The added copper element makes them resistant to non-oxidizing acid corrosion. S32760 is also resistant to strong alkali corrosion. However, duplex steels S32760, F55, and 1.4501 are not suitable for use at long-term working temperatures above 300°C, because above this temperature, the toughness of the material will drop significantly.
Stainless Steel
Material: AISI904L, N08904, 1.4539
904L is a low carbon austenitic stainless steel designed for use in severe corrosive conditions. Compared to 316L, 904L stainless steel has more chromium, nickel, molybdenum, and copper. Therefore, 904L steel is more wear-resistant and heavier, but there is not much difference in hardness. 904L stainless steel is also called "rolex 904l​", which means that Rolex uses 904L to make watch cases.
Stainless Steel
Material: Grade S31254, 1.4547, F44
254SMO (UNS S31254 / EN 1.4547 / F44) is a 6% molybdenum super-austenitic stainless steel engineered for the most aggressive chloride environments. With a Pitting Resistance Equivalent Number of approximately 42–44 — nearly double that of 316L — and a critical pitting temperature of ≥ 50°C per ASTM G48, it is a standard material for seawater reverse osmosis.
Inconel Steel
Material: Inconel 625, UNS N06625, 2.4856
 
Inconel 625 is a nickel-chromium high-temperature alloy known for its corrosion resistance, high-temperature strength, oxidation resistance, and ease of fabrication. It was originally created for high-temperature steam pipings, but due to its excellent comprehensive properties, it is now widely used in extremely harsh corrosive and high-temperature environments.
Hastelloy Steel
Material: Hastelloy C276, UNS N10276, 2.4819
Hastelloy C276 is as nickel the main component, and molybdenum, chromium, and a small amount of iron, tungsten, etc. It exhibits excellent comprehensive performance in strong corrosive environments, so it is called the "king of corrosion-resistant alloys". Hastelloy C276 is known for its excellent mechanical properties, including high strength, toughness and ductility. In addition, the alloy can withstand high temperatures and high pressures, making it suitable for environments in the oil and gas, chemical and petrochemical industries.

How to Choose Hastelloy C276 Pipes: Selection Guide

Choosing C276 pipe comes down to five decisions in a fixed order - product specification, size and schedule, verified wall thickness, matching components and certification. Most costly mistakes are not metallurgical. They are a welded pipe supplied where seamless was required, a wall thickness that ignored the 12.5% mill tolerance, or a certificate that never arrived.

Equivalent Grades of Hastelloy C276: The Complete Cross-Reference Guide to UNS N10276

Hastelloy C276 is UNS N10276. Its internationally recognized equivalents are W.Nr. 2.4819 / NiMo16Cr15W (Germany and EN standard), NW 0276 (Japan, JIS), NS334 (China, GB/T 15008), NC17D (France, AFNOR), NCF 276 (South Korea, KS), and NiMo16Cr15W (ISO 6208). All designate the same nickel-molybdenum-chromium-tungsten alloy - provided the certificate of test matches the UNS N10276 chemistry limits.

Hastelloy C276 vs Incoloy 825: Which Alloy Should You Choose?

Pick Hastelloy C276 when hydrochloric acid, hot chlorides, wet chlorine or mixed oxidising-reducing acids are in the stream. Pick Incoloy 825 when the duty is moderate sulfuric or phosphoric acid, sour gas inside its ISO 15156-3 envelope, or any large-tonnage job where paying two to two-and-a-half times more per kilogram buys nothing.
