Nitrided brittleness: less than grade 2
Surface roughness: Ra 0.4
Screw straightness: 0.015 mm
Surface chromium-plating's hardness after nitriding: ≥900HV
Chromium-plating depth: 0.025~0.10 mm
Alloy Hardness:
Alloy depth: 0.8~2.0 mm
High temperature resistance, no deformation under high temperature;
Wear resistance, long service life;
Corrosion resistance, corrosive materials;
High strength, can withstand high torque, high speed;
Good cutting performance ;
Residual stress after heat treatment is small, thermal deformation is small, and the like.
