317L stainless steel, also known as UNS S31703, is a low-carbon, high-alloy austenitic stainless steel. It contains higher levels of chromium, nickel, and molybdenum compared to standard 304/304L stainless steel. Here’s how it is used in various industries:
Remember that the specific application and conditions determine the suitability of 317L stainless steel. Always consult with materials engineers and industry experts to ensure proper material selection for your specific project!
317L (UNS S31703) is a low carbon corrosion resistant austenitic chromium-nickel-molybdenum stainless steel. The high levels of these elements assure the steel has superior chloride pitting and general corrosion resistance to the conventional 304/304L and 316/316L grades. The steel provides improved resistance relative to 316L in strongly corrosive environments containing sulfurous media, chlorides, and other halides.
The low carbon content of 317L enables it to be welded without intergranular corrosion resulting from chromium carbide precipitation enabling it to be used in the as-welded condition.
The grade 317L is non-magnetic in the annealed condition. It cannot be hardened by heat treatment; however the material will harden due to cold working. 317L can be easily welded and processed by standard shop fabrication practices.
Seamless Stainless Steel U-tube is a specific type of heat exchanger tube that is bent into a"U"shape after the manufacturing process. It is crafted from a single, solid billet of stainless steel and, like other seamless tubes, has no weld joint. This seamless construction is crucial for maintaining structural integrity and reliability, especially in high-stress and corrosive environments. The unique U-shape allows for thermal expansion and contraction, making it ideal for shell and tube heat exchangers. It enables a single-pass fluid flow on the shell side and a multi-pass flow on the tube side, maximizing heat exchange efficiency and reducing the overall footprint of the heat exchanger.① STANDARD: ASTM A213② OD RANGE : 6-50.8MM③ THICKNESS RANGE: 0.5-9MM④ U-BEND & STRAIGHT
TP317LMn Seamless Stainless Steel Pipe is a high-performance, low-carbon, austenitic stainless steel pipe with increased levels of Molybdenum (Mo) and Nitrogen (N). This composition enhances its corrosion resistance and mechanical strength, particularly when compared to standard grades like 316L and 317L.It is typically manufactured to specifications such as ASTM A312/ASME SA312 for seamless pipe intended for high-temperature and general corrosive service, with the grade designation TP317LMn or UNS S31726.① STANDARD: EN10216-5/ ASTM A312/ ASTM A249/ ASTM A269/ GOST 9940 /GOST 9941...② OD RANGE : 6-762MM③ THICKNESS RANGE: 1-65 MM

Seamless 654SMO Super Stainless Steel Tube UNS S32654, W. Nr. 1.4652) is a high-performance super austenitic stainless steel alloy, often classified as a "super stainless steel" due to its exceptional corrosion resistance and mechanical strength. Developed for the most demanding environments, it features unusually high levels of chromium (24%), molybdenum (7-8%), nickel (23%), and nitrogen (0.45-0.55%), enabling pitting resistance equivalent number (PREN) values exceeding 50—comparable to top nickel-based alloys like Hastelloy. The seamless design ensures superior integrity for high-pressure, high-temperature, and corrosive applications, avoiding weld-related vulnerabilities. It is twice as strong as conventional austenitic grades like 304 or 316 while maintaining excellent ductility and toughness.① STANDARD: ASTM A312/EN10216-5/GBT14976.② OD RANGE : 6.35-257MM③ THICKNESS RANGE: 0.89-35MM
