Cadmium Plating

Cadmium is a generally bright silvery white, supplementary treatments for Type II can be golden, iridescent, amber, black or olive drab. Cadmium corrosion resistance is very good, especially with Type II finish. Type II shows no corrosion effects after 96 hours of 5% salt spray exposure. Steel parts with UTS of 150,000 psi and above, which are machined, ground, cold formed or cold straightened after heat treatment, may require stress relief before cleaning and plating. Steel parts over Rc 33 hardness shall be given a post bake for the relief of hydrogen embrittlement
