Hot Rolled 1211 Carbon Steel
Hot rolled SAE-AISI 1211 is SAE-AISI 1211 steel in the hot worked condition. The graph bars on the material properties cards below compare hot rolled SAE-AISI 1211 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.
