AISI 317L (1.4438, S31703) Stainless Steel Seamless Pipes
317L is molybdenum bearing austenitic stainless steel similar to 316, but with higher molybdenum alloy content. It is also known as UNS S31700, and is primarily comprised of 18% to 20% chromium and 11% to 15% nickel. 317L offers higher creep, stress-to-rupture, and tensile strength at elevated temperatures than conventional stainless steels. It is a low carbon grade which provides resistance to sensitization during welding and other thermal processes. 317L has excellent corrosion resistance and is used mainly in high acidic chloride media, such as those encountered in pulp and paper mills.
