Cold Finished 316L Stainless Steel

Cold finished AISI 316L is AISI 316L stainless steel in the cold worked (strain hardened) condition. The graph bars on the material properties cards below compare cold finished AISI 316L to: wrought austenitic stainless steels (top), all iron alloys (middle), and the entire database (bottom). A full bar means this is the highest value in the relevant set. A half-full bar means it's 50% of the highest, and so on.
