M50 Tool Steel

M50 is a high speed too steel that is melted as AOD + ESR, AOD + VAR, or VIM + VAR melt type.  This grade has increased molybdenum which helps improve wear resistance and strength at high temperatures.  This alloy is often used in aerospace bearing applications where good fatigue strength is critically important.
