Scope

This standard covers the process and materials required for the electro-deposition of nickel on high strength steel substrates. Electro-deposited nickel is used for wear resistance, heat resistance, and as an undercoat for precious metals. Subsequent heat treating techniques needed to insure low hydrogen embrittlement of steel are also described. This standard meets the performance requirements of SAE AMS-QQ-N-290 and may be used when SAE AMS-QQ-N-290 is specified provided any unique requirements of SAE AMS-QQ-N-290 are complied with.
