The 317L Stainless Steel Pipe is a premium, molybdenum-enriched, low-carbon austenitic steel. Enhanced with additional chromium, nickel, and molybdenum, it offers superior resistance to corrosion and chemical reactions involving sulfite, acetic, formic, citric, and tartaric acids. Thanks to its low carbon content, the 317L Pipe withstands sensitization during welding and provides exceptional creep, rupture stress, and tensile strength at high temperatures. While nonmagnetic in its annealed state, it may acquire slight magnetism post-welding.
The 317L seamless pipe excels in a variety of challenging environments, including sulfur handling, pulp liquors, acid dyes, acetylation and nitration mixtures, bleaching solutions, heavy coal, and petroleum processing, and numerous chemical compounds. Additional applications of the 317L alloy include:
