EASTERN STAINLESS Type 317L is an austenitic chromium-nickel stainless containing low carbon (0.03% max.) and an addition of molybdenum (3.00-4.00%). This steel was developed primarily to resist more effectively the attack by sulfurous acid than is provided by some of the other competitive stainless steels. Its proven ability to resist corrosion had broadened its use considerably and now it is used for many other industrial applications. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as creep. It also includes information on high temperature performance and corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: SS-453. Producer or source: Eastern Stainless Steel Company.
