ASTM A210 Grade C Medium-Carbon Steel
ASTM A210 grade C is a type of ASTM A210 steel. The graph bars on the material properties cards below compare ASTM A210 grade C 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.
