Stainless steel grade 317L is a low carbon version of grade 317 stainless steel. It has the same high strength and corrosion resistance as 317 steel but can produce stronger welds due to the low carbon content. 317L is a molybdenum containing, low carbon austenitic stainless steel with increased additions of chromium, nickel, and molybdenum for better corrosion resistance and increased resistance to chemical attack for sulfurous, acetic, formic, citric, and tartaric acids. Due to its low carbon content, 317L also provides resistance to sensitization when welded and higher creep, stress to rupture, and tensile strength at elevated temperatures. It is non-magnetic in the annealed condition but may become slightly magnetic after welding.
317L has excellent corrosion resistance in a wide range of chemicals, especially in acidic chloride environments such as those encountered in pulp and paper mills. Increased levels of chromium, nickel and molybdenum compared to 316L stainless steel improve resistance to chloride pitting and general corrosion. Resistance increases with molybdenum alloy content. 317L is resistant to sulfuric acid concentrations up to 5 percent at temperatures as high as 120°F (49°C). At temperatures under 100°F (38°C) this alloy has excellent resistance to solutions of higher concentration. However, service tests are recommended to account for the affects of specific operating conditions that may affect corrosion behavior. In processes where condensation of sulfur-bearing gases occurs, 317L is much more resistant to attack at the point of condensation than conventional alloy 316. The acid concentration has a marked influence on the rate of attack in such environments and should be carefully determined by service tests.
Our Stainless Steel 317L Pipe Fittings consist of a small quantity of Molybdenum which makes them versatile and usable under several chemical surroundings. We are a manufacturer, trader, stockist, supplier and exporter of SS 317L Pipe Fitting that have a massive tensile strength of 515 Mpa and have resistive powers against chemical attacks initiated by sulfur, acetic, formic, and other forms of acids. SS 317L Butt weld Elbow are offered after a variety of surface treatments that only add to their versatility. JN Alloy are reputed stockist of ASTM A403 SS 317 Butt weld Fittings such as SS WP317 butt weld tee, DIN 1.4449 End Pipe Cap, ANSI B16.9 SS 317L reducer, ASME 16.28 317 cross, Werkstoff No 1.4438 butt weld elbow, MSS SP 43 SS 317 stub ends etc in ready stock.
Stainless Steel 317L covers the standard for wrought austenitic stainless steel fittings for pressure piping applications. The material for Pipe Fitting shall consist of forgings, bars, plates, or seamless or welded tubular products. All fittings shall undergo heat-treatment. Chemical and product analyses shall be performed and shall conform to the required chemical composition in carbon, manganese, phosphorus, sulfur, silicon, chromium, molybdenum, and titanium. Tension test shall be done on the fitting material to determine the tensile properties such as yield strength and tensile strength. Fittings supplied under this specification shall be examined visually for surface discontinuities, surface checks, and mechanical marks.
A butt weld Pipe fitting is designed to be welded on site at its end(s) to connect pipe(s) together and allow change in direction or pipe diameter, or branching or ending. This fitting then becomes part of a system for transporting fluids (oil, gas, steam, chemicals, …) in a safe and efficient manner, over short or long distances. Other types of fittings can be threaded or socket welded.
Several grades of austenitic stainless steel 317l alloys are included in this specification. Grades are designated with a prefix, based on the applicable ASTM/ASME or MSS standards. For each of the WP stainless grades, several classes of fittings are specified, to indicate whether seamless or welded construction was utilized. Class designations are also utilized to indicate the nondestructive test method and extent of nondestructive examination. A general summary of the fitting classes applicable to all WP grades of stainless steel follows.

317L stainless steel’s pipe fittings claim to fame lies in its superior corrosion resistance, especially against chlorides. It’s no surprise then that one of its primary applications is in marine environments. Stainless steel wire 317L is used for fixtures, fastenings, and structures where resistance to saltwater corrosion is vital. From the nets of fishing vessels to the ropes securing ships to their moorings, this grade of stainless steel ensures longevity and durability.
The robust nature of 317L stainless steel pipe fittings makes it a favorite in petrochemical plants. These facilities require materials that can withstand aggressive chemicals, fluctuating temperatures, and high-pressure scenarios. SS 317L pipe fittings is often chosen for ladders, cages, safety barriers, and even for certain piping systems, ensuring that the infrastructure remains intact even under the most challenging conditions.
In the medical realm, hygiene, precision, and longevity are non-negotiable. Surgical instruments, braces, pins, and certain implants often use 317L stainless steel pipe fittings due to its anti-corrosive properties and ability to be sterilised repeatedly without degradation.
The aesthetic appeal of stainless steel, combined with its functional benefits, makes it a favorite in modern architecture. SS 317L Grade is used in balustrades, sculptures, decorative screens, and even in certain structural elements. Its ability to resist corrosion and retain its luster means that structures remain visually appealing for decades.
At first, the textile and paper industries might seem like unusual candidates for 317L stainless steel pipe fittings use. However, consider the processing equipment—many machines that manufacture textiles or process paper come into contact with chemicals and dyes that can be corrosive. 317L stainless steel pipe fittings offer corrosion resistance, ensuring that these machines last longer and operate more efficiently.
In the world of food production, cleanliness is paramount. Equipment, especially those used in processing acidic foods like citrus fruits or tomatoes, needs to be resistant to corrosion. 317L stainless steel pipe fittings, gratings, and other components are chosen for their ability to come into contact with food without corroding or leaching harmful substances.
