M50NIL Bearing Steel

M50NIL is a high speed bearing steel that is melted as VIM + VAR melt type.  This grade has increased molybdenum which helps improve wear resistance and strength at high temperatures.  This grade is very similar to M50 alloy but is a low carbon, high nickel version resulting in much stronger toughness. This alloy is used primarily in aerospace bearing applications where good fatigue strength is critically important.
