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.
