Steel grade EN36

EN36 (655M13) Engineering steel

EN36 (655M13) is a carburising steel grade with very high surface strength with a soft but strong core. The material retains a remarkable degree of toughness. With high tensile strength, EN36 is used in the production of numerous high strength parts including crankshafts in the automotive and aerospace sector.

EN36 (655M13) steel grade offers high tensile strength and deep hardening due to the alloys nickel and chrome content. With excellent toughness and fatigue resistance, this carburising steel grade offers a very high surface strength with a soft but strong core.

Steel stock range

High Peak Steels stock EN36 (655M13) in black steel round bar and bright steel round bar. We also offer processing options throughout the Group with over thirty power saws available to cut your material to size. It is just as economical for us to cut a single one off blank to large production runs.
