This specification covers the requirements for cadmium plating of carbon steel and low alloy steel parts for protection against corrosion. Parts made of steel of specified minimum tensile strength exceeding 90 tonf/in² or of equivalent hardness (see Clause 2.3) are subject to the special limitations and requirements of D.T.D. 934. The specification also covers the requirements for cadmium plating of copper-base materials and corrosion-resisting steels for the reduction of contact corrosion of less noble metallic materials.

Cadmium plating shall not be used on parts which are liable to be subjected to temperatures in excess of 250°C (480°F).
