Technical Note: Maraging steels are iron alloys: a. Generally characterised by high nickel, very low carbon content and use substitutional elements or precipitates to produce strengthening and age- hardening of the alloy; and b. Subjected to heat treatment cycles to facilitate the martensitic transformation process (solution annealed stage) and subsequently age hardened (precipitation hardened stage).
