316 and 316L Stainless Steel Sheet, Coil & Bar - AMS 5524, 5507, UNS S31600, S31603

316 / 316L are austenitic stainless steels that contain molybdenum, which increases their resistance to many chemical corrodents and marine environments. 316L is an extra low carbon version of 316 stainless steel. These materials are more resistant to general corrosion and pitting/crevices than conventional austenitic stainless steels. They also offer higher creep, stress-to-rupture and tensile strength at elevated temperatures, excellent corrosion resistance and strength properties, and they are well suited for fabricated or formed applications.
