EN 1.8896 (E355M) Steel

EN 1.8896 steel is an alloy steel formulated for primary forming into wrought products. Cited properties are appropriate for the thermomechanically rolled condition. 1.8896 is the EN numeric designation for this material. E355M is the EN chemical designation.

It has a moderately low electrical conductivity among EN wrought alloy steels. In addition, it has a moderately high thermal conductivity and a moderately low base cost.

The graph bars on the material properties cards below compare EN 1.8896 steel to: EN wrought 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.
