EN 1.0225 (E275) Non-Alloy Steel
EN 1.0225 steel is a carbon (non-alloy) steel formulated for primary forming into wrought products. 1.0225 is the EN numeric designation for this material. E275 is the EN chemical designation.
The properties of EN 1.0225 steel include three 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 1.0225 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.
