Cold Drawn 1547 Carbon Steel
Cold drawn SAE-AISI 1547 is SAE-AISI 1547 steel in the cold worked (strain hardened) condition. It has the highest strength compared to the other variants of SAE-AISI 1547 steel. The graph bars on the material properties cards below compare cold drawn SAE-AISI 1547 to: wrought resulfurized carbon 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.
