# Cold Drawn 1023 Carbon Steel

Cold drawn SAE-AISI 1023 is SAE-AISI 1023 steel in the cold worked (strain hardened) condition. The graph bars on the material properties cards below compare cold drawn SAE-AISI 1023 to: wrought carbon or non-alloy 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.
