EN 1.8895 (E275M) Steel
EN 1.8895 steel is an alloy steel formulated for primary forming into wrought products. Cited properties are appropriate for the thermomechanically rolled condition. 1.8895 is the EN numeric designation for this material. E275M is the EN chemical designation.
It has a very low tensile strength among EN wrought alloy steels. In addition, it has a moderately low electrical conductivity and a moderately high thermal conductivity.
The graph bars on the material properties cards below compare EN 1.8895 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.
