This specification has been declared “NONCURRENT” by the Aerospace Materials Division, SAE, as of August 2009. It is recommended, therefore, that this specification not be specified for new designs. “NONCURRENT” refers to those specifications which have previously been widely used and which may be required for production or processing of existing designs in the future. The Aerospace Materials Division, however, does not recommend these specifications for future use in new designs. “NONCURRENT” specifications are available from SAE upon request.
This specification covers the requirements for electrodeposited zinc plating. Unless otherwise stated on the engineering drawing, high strength steel parts having a hardness of 45 HRC or greater shall not be electroplated.
