Hard Chrome

Hard chrome plating is an electroplating process in which a layer of chromium is applied to a surface to improve corrosion and wear resistance, reduce friction, and extend the life of parts used in extreme working environments. A wide range of materials, component sizes and complexity can be plated making hard chrome a popular choice for many industrial and commercial applications.
