Annealed and Cold Drawn 1049 Carbon Steel

Annealed and cold drawn SAE-AISI 1049 is SAE-AISI 1049 steel in the annealed and cold-drawn condition. The graph bars on the material properties cards below compare annealed and cold drawn SAE-AISI 1049 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.
