EN 1.0599 (E420J2) Non-Alloy Steel

EN 1.0599 steel is a carbon (non-alloy) steel formulated for primary forming into wrought products. Cited properties are appropriate for the normalized condition. 1.0599 is the EN numeric designation for this material. E420J2 is the EN chemical designation.

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

The graph bars on the material properties cards below compare EN 1.0599 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.
