We are well-known exporters and manufacturers of 317 / 317L stainless steel tube, which is austenitic stainless steels containing molybdenum. Grade 317L is a modified version of these 317 stainless steel seamless pipes, where it has high strength and corrosion resistance.
Our 317L stainless steel welded pipe is a low carbon austenitic stainless steel that contains moly through increased additions of chromium, nickel and molybdenum for better corrosion resistance and greater resistance to chemical attack from sulfurous, acetic, acids. formic, citric and tartaric. Our 317L stainless steel seamless pipes have superior creep and tensile strength at high temperatures.
Alloy 317L (UNS S31703) is a molybdenum bearing austenitic stainless steel with much higher resistance to chemical attack compared to conventional nickel-chromium austenitic stainless steels such as Alloy 304. In addition, Alloy 317L offers greater resistance to lateral elongation, tensile stress, and high temperature stress than conventional stainless steels. It is a low carbon steel or grade&"L GG" It provides resistance to sensitization during welding and other thermal processes.
