Stainless Steel 317 comprises of nickel, chromium and molybdenum formulated especially for increased strength and high corrosion resistance. The high steel alloy resist pitting in acetic and phosphoric acids. It also has characteristics of higher stress to rupture ratio and tensile strength. The cold work will provide this high steel alloy extra increase in both hardness and strength.
Stainless Steel 317L is an low carbon version of SS 317, with all the same characteristic.
