New in our range: Maraging steel C 300

26 February 2015 |

Maraging steel is an 18% nickel, cobalt-reinforced steel with excellent mechanical and heat treatment properties. The yield strength is around 870 N / mm² which after aging is increased to about 1980 N / mm². The hardness is about 53 HRC after aging. The material is therefore easy to process and shape before aging.

Aging takes place at 480 ° C for 3-5 hours.

Marage aging means that precipitation hardens martensite from a low-carbon steel. Instead of using carbides (as in ordinary hardenable steels), you have additives of metal compounds such as Ni3Mo, also additives of Al, Ti and Nb are used.

The material is excellent for welding with both TIG and MIG.

Typical applications are tools for profiles, shafts, gears, fasteners and also engine covers for missiles and rockets and landing gear.
