EN 1.0580 (E355) Non-Alloy Steel
EN 1.0580 steel is a carbon (non-alloy) steel formulated for primary forming into wrought products. 1.0580 is the EN numeric designation for this material. E355 is the EN chemical designation. It can have the lowest ductility among the wrought carbon or non-alloy steels in the database.
The properties of EN 1.0580 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 1.0580 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.
