maraging steels
Nickel in the amount of 18.5 percent is the principal alloying element in the maraging steels. Other alloying elements are cobalt, molybdenum, aluminum and titanium. With a maximum carbon content of 0.030 percent, these steels are essentially carbon-free. They utilize the soft, ductile, iron-nickel martensite, which can be age-hardened by additions of other alloying elements. The most common maraging steel grades are 18Ni(200), 18Ni(250), 18Ni(300) and 18Ni(350). The numerical designations represent ultimate tensile strength of these grades. Maraging steels are used in the aerospace industry and for making tools (various dies, trim knives and springs).
