Description
Maraging steels were developed in the late 1950’s at the Internatinal Nickel Company for applications requiring ultrahigh strength in combination with good fracture toughness. This family of materials includes low-carbon martensitic steels, which initially contained 18 to 25 percent nickel and substitutional elements such as cobalt, molybdenum and titanium. However, among modern maraging steels a large number of modified versions exist in which the nickel content has been reduced. The term maraging is coined from a combination of martensite and age-hardening.
