M-50 is a premium-melted alloy featuring great resistance to multi-axial stresses and softening at high service temperature.
In addition, the alloy is known for excellent resistance to oxidation.
M-50 possesses high compressive strength and is typically used for components requiring high wear resistance and strength at elevated temperatures.
M-50 is used in various bearing and missile industry applications such as for bearings in aircraft and gas turbine engines in operating environments up to approximately 700°F (371°C).
