Maraging Steel

Maraging steels are steels with 18% nickel as their primary strengthening element and either cobalt (C-alloys) or titanium (T-alloys) as their secondary alloying elements. The name derives from the substructure of the material and its subsequent treatment used to give this material its remarkable properties, which are the martensitic substructure (Mar) and aging. These two features combine to offer a material with excellent tensile and yield strengths, toughness, fatigue strength, hardness, workability, weldability, machinability, and a low coefficient of thermal expansion.

​

These alloys are used in the extremes of industry, where their properties offer unrivaled performance in applications such as landing gear on aircraft, jet engine and helicopter driveshafts, transmission shafts, couplings, and motorsport components.

​

With their aptitude for machining in the annealed condition and excellent post-machining surface finish, these alloys are usually supplied in bar or billet form, but other shapes are also available.
