42CrMo hard chrome plated steel bars are chromium-plated steel products that can be supplied as piston rods in standard hydraulic and pneumatic applications. The hard chrome plated steel bar is normally used in conditions of high stress, friction and harsh climactic environments.so the quality of the base metal and subsequent surface treatment are of paramount importance. Wear resistance, corrosion resistance, surface smoothness, high yield strength and uniform quality are essential properties of hard chrome bar.
Hard Chrome Rods are generally produced from steel bars combining high strength with excellent machinability and weldability. Common applications are found in agricultural machinery, production equipment, cranes, garbage compactors, lifters etc.
