Cold Finished 305 Stainless Steel
Cold finished AISI 305 is AISI 305 stainless steel in the cold worked (strain hardened) condition. The graph bars on the material properties cards below compare cold finished AISI 305 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.
