EN32 Case Hardening Steel

EN32 (080M15) is bright drawn engineering steel with low tensile strength and is intended for use in general engineering applications, particularly for low stressed components. Classed as an unalloyed low carbon engineering steel grade, when case hardened the material offers a hard, outer surface with a tough internal core. Tempering of EN32 is recommended to offer maximum case toughness and stress relief with a tempering range from 150 – 200°C. A core strength of up to 490 N/mm² can be achieved for components when carburized. EN32 should be considered for any lightly stressed applications where good wear resistance is a consideration. Other engineering steels should be considered where extra strength is required. EN32 (080M15) can be viewed as a ‘crossover’ material as essentially it is the same product as EN3B but is marketed and supplied specifically for case hardening work.
