EN 1.0213 (C8C) Non-Alloy Steel

EN 1.0213 steel is a carbon (non-alloy) steel formulated for primary forming into wrought products. 1.0213 is the EN numeric designation for this material. C8C is the EN chemical designation.

It has a fairly high thermal conductivity among wrought carbon or non-alloy steels. In addition, it has a fairly low electrical conductivity and can have a moderately low tensile strength.

The properties of EN 1.0213 steel include four common variations. This page shows summary ranges across all of them. For more specific values, follow the links immediately below. The graph bars on the material properties cards further below compare EN 1.0213 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.
