Maraging steel 18Ni300, 1.2709

Maraging steel is a carbon-free iron-nickel alloy where cobalt, molybdenum, titanium and aluminium are added. The term maraging steel is a blend of the two words ‘martensitic’ and ‘aging’, reflecting the special heat treatment process when steel microstructure transforms into martensite during aging. Maraging steels are known for their superior strength and toughness without losing ductility.
