EN 1.0117 (S235J2) Non-Alloy Steel
EN 1.0117 steel is a carbon (non-alloy) steel formulated for primary forming into wrought products. Cited properties are appropriate for the hot worked condition. 1.0117 is the EN numeric designation for this material. S235J2 is the EN chemical designation.
It has a moderately low tensile strength and a moderately high ductility among wrought carbon or non-alloy steels.
The graph bars on the material properties cards below compare EN 1.0117 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.
