N135M Low Alloy Steel

N135M is a low alloy steel melted as AOD + VAR.  This grade is a nitriding grade capable of producing a very high case hardness while still maintaining high strength in the core.  The increased wear resistance from nitriding makes this grade perfect for highly stressed gears in the rotorcraft industry.
