ASTM A210 Medium-Carbon Steel
ASTM A210 steel is a carbon (non-alloy) steel formulated for primary forming into wrought products. It has a fairly high ductility among the wrought carbon or non-alloy steels in the database.
The properties of ASTM A210 steel include two common variations. This page shows summary ranges across both of them. For more specific values, follow the links immediately below. The graph bars on the material properties cards further below compare ASTM A210 steel 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.
