EN 1.0456 (E275K2) Non-Alloy Steel

EN 1.0456 steel is a carbon (non-alloy) steel formulated for primary forming into wrought products. 1.0456 is the EN numeric designation for this material. E275K2 is the EN chemical designation.

It has a moderately low thermal conductivity among wrought carbon or non-alloy steels. In addition, it has a moderately high embodied energy and a moderately high base cost.

The properties of EN 1.0456 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 EN 1.0456 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.
