Hard chrome plated hardened round bar Introduction
Hard chrome plated hardened round bar adopts rolling process, which improves the surface anti-corrosion ability, and can delay the production or expansion of fatigue crack, thus improving the fatigue strength of cylinder rod. Roll forming, by forming a layer of cold work roll surface hardening layer, reducing the grinding pair of elastic and plastic deformation of the contact surface, thus improve the abrasion resistance on the surface of the cylinder rod, at the same time avoid the burn caused by grinding.
