Description / Abstract:


This specification covers the requirements for electrodeposition of a zinc-nickel alloy and the properties of the deposit.


Zinc-nickel plating has been used typically to provide corrosion resistance to steel parts that may operate at elevated temperatures (See 1.3) but usage is not limited to such applications. See 8.9 and 8.10.


Plating covered by this specification is classified as follows:

Type 1 As-plated without supplementary treatment, service temperature 500 °F (260 °C) max.

Type 2 As-plated with supplementary chromate treatment

Grade A Hexavalent chromate treatment, service temperature 250 °F (121 °C) max.

Grade B Trivalent chromium treatment, service temperature 375 °F (191 °C) max.

Type 3 As-plated with supplementary phosphate treatment (Adhesion base for primer/paint), service temperature 350 °F (177 °C) max.

Unless a type is specified, Type 2 shall be supplied.

For Type 2 plating, if no grade is specified, Grade A shall be supplied.

Safety - Hazardous Materials

While the materials, methods, applications, and processes described or referenced in this specification may involve the use of hazardous materials, this specification does not address the hazards that may be involved in such use.
