Cold Drawn 303 Stainless Steel
Cold drawn AISI 303 is AISI 303 stainless steel in the cold worked (strain hardened) condition. The graph bars on the material properties cards below compare cold drawn AISI 303 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.
