Osprey® MAR-50 Co-free maraging steel

Osprey® MAR-50 Co-free is a maraging steel free of cobalt, with reduced amount of nickel and an addition of chromium, to obtain a nearly fully martensitic microstructure already in the Laser - Powder Bed Fusion (L-PBF) as-built condition.

This alloy has been developed using the latest metallurgical modelling systems. It can be directly aged to achieve levels of material performances including strength, hardness and toughness comparable to the conventional 18Ni300 maraging steel.

Osprey® MAR-50 Co-free is typically used for conformal-cooled mould tooling and rubber-tyre mould (sipes) applications.
