This specification covers the engineering requirements for an electrodeposit of cadmium 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 which may operate in service up to 900 degrees F (482 degrees 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 degrees F (338 degrees C).
