Maraging 250, 300, 350 Alloy Steels
Maraging steels are iron-nickel alloys with absence of carbon and have metals such as molybdenum, cobalt, titanium and aluminum. The alloys have ultra-high strength, superior toughness characteristics and weldability.
Maraging 300 is also called Vascomax 300 and is a special class of high-strength stainless steel that derives its strength not from carbon but from precipitation of intermetallic compounds. Maraging 300 is an 18% Nickel and Cobalt strengthened steel. It is a steel alloy with an iron base, where molybdenum, nickel and cobalt make up the additional alloy components. Age hardening may be done to a strength level of 300 ksi with hardness in the order of Rockwell C 53. It is produced using the vacuum induction melting (VIM) process followed by the vacuum arc remelting (VAR) process. The density of maraging 300 steel is 8.0 g/cm3.
