scope:

This standard covers the process and materials required for the electrodeposition of cadmium on high strength steel substrates. Subsequent heat treating techniques needed to insure low embrittlement of steel are also described. This process is not authorized for use on steel heat treated above 1.65 × 10⁹ Pascals (Pa)[240,000 pounds per square inch (psi)] without the approval of the applicable Procuring Activity. Plating of steel heat treated above 1.65 × 10⁹ Pascals (Pa) (240,000 psi) is authorized only on individual part evaluation.

This standard meets and exceeds the requirements of QQ-P-416 and may be used whenever plating per QQ-P-416.

Cadmium plating covered by this standard shall be of the following classes:

Class 1 0.013mm (0.0005 inch) thick minimum Class 2 0.008mm (0.0003 inch) thick minimum Class 3 0.005mm (0.0002 inch) thick minimum
