Annealed and Cold Drawn 1070 Carbon Steel
Annealed and cold drawn SAE-AISI 1070 is SAE-AISI 1070 steel in the annealed and cold-drawn condition. It has the lowest strength and lowest ductility compared to the other variants of SAE-AISI 1070 steel.
The graph bars on the material properties cards below compare annealed and cold drawn SAE-AISI 1070 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.
