Engineering steels - Martensitic precipitation hardening (MARAGING) steels

Maraging steels are high-strength, tough steels of the Fe-18% Ni-Co-Mo type. Strengths of over 2000 MPa can be achieved with a simple, low-distortion heat treatment. These steels are used in lightweight construction in the aerospace industry, in mechanical engineering and toolmaking, e.g. for fasteners, shafts, springs and gear parts.
