EN 1.0108 (P195TR2) Non-Alloy Steel

EN 1.0108 steel is a carbon (non-alloy) steel formulated for primary forming into wrought products. Cited properties are appropriate for the normalized condition. 1.0108 is the EN numeric designation for this material. P195TR2 is the EN chemical designation.

It has a fairly high ductility and a fairly low tensile strength among wrought carbon or non-alloy steels.

The graph bars on the material properties cards below compare EN 1.0108 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.
