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.

Thanks to its low carbon content, maraging steel has good machinability. Maraging steels also offer good weldability, but must be aged afterwards to restore the original properties to the heat-affected zone. When a maraging steel part is heat-treated, the alloy has very little dimensional change. This is why it is often machined to its final dimensions before the heat treatment.

Maraging steels have very high and stable mechanical properties. The steels are used for construction components in the aerospace industry, as well as for production of different types of tools and moulds. The ability of the additive manufacturing process to create internal cooling channels makes maraging steel powder a great choice for manufacturing of polymer injection moulds.
