EN 1.0220 (E260) Non-Alloy Steel

EN 1.0220 steel is a carbon (non-alloy) steel formulated for primary forming into wrought products. Cited properties are appropriate for the cold worked (strain hardened) condition. 1.0220 is the EN numeric designation for this material. E260 is the EN chemical designation.

It has a fairly low tensile strength among the wrought carbon or non-alloy steels in the database.

The graph bars on the material properties cards below compare EN 1.0220 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.
