EN 1.0920 (E355K2) Non-Alloy Steel
EN 1.0920 steel is a carbon (non-alloy) steel formulated for primary forming into wrought products. Cited properties are appropriate for the normalized condition. 1.0920 is the EN numeric designation for this material. E355K2 is the EN chemical designation.
It has a fairly high base cost among wrought carbon or non-alloy steels. In addition, it has a fairly high embodied energy and a moderately high electrical conductivity.
The graph bars on the material properties cards below compare EN 1.0920 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.
