Cold Finished 316 Stainless Steel
Cold finished AISI 316 is AISI 316 stainless steel in the cold worked (strain hardened) condition. It has the lowest strength compared to the other variants of AISI 316 stainless steel. The graph bars on the material properties cards below compare cold finished AISI 316 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.
