This specification covers the requirements for an electrodeposit of cadmium diffused into an electrodeposit of nickel on carbon, low-alloy, and corrosion-resistant steels. This coating has been used typically to prevent corrosion of carbon, low-alloy, and corrosion resistant steel parts that may operate in service up to 900 °F (482 °C), but usage is not limited to such applications. This process is not suitable for use on parts of complex shape where minimum nickel plate thickness requirements cannot be met and on parts whose hardness or strength would be reduced below drawing or specification requirements by heating to 640 °F (338 °C).
