EN 1.1104 (P275NL2) Non-Alloy Steel

EN 1.1104 steel is a carbon (non-alloy) steel formulated for primary forming into wrought products. Cited properties are appropriate for the normalized condition. 1.1104 is the EN numeric designation for this material. P275NL2 is the EN chemical designation.

It has a fairly high base cost among wrought carbon or non-alloy steels. In addition, it has a moderately high embodied energy and a moderately high electrical conductivity.

The graph bars on the material properties cards below compare EN 1.1104 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.
