Description:
Nickel and chrome plating piston rod1.Material:SAE1035/SAE1045/SAE5140
2.Surface:Nickel and Chromed
Nickel and chromeplating piston rod
Advantage of nickel and chrome plated steel
The nickel layer is completely free from cracks, pores and the base material is isolated to
the atmospheric corrosion, while the same time the chrome layer insure a very good wear resistance.
