MIL-STD-1501E, DEPARTMENT OF DEFENSE STANDARD PRACTICE: CHROMIUM PLATING, LOW EMBRITTLEMENT, ELECTRO-DEPOSITION (01 MAR 2007)., This standard covers the engineering requirements for electro-deposition of hard chromium on high strength steel substrates and the properties of deposit. Subsequent heat treating techniques needed to insure low hydrogen embrittlement of steel are described. Chromium plated to this standard will meet the performance requirements of SAE-AMS-QQ-C-320. This standard may be used whenever SAE-AMS-QQ-C-320 is specified, provided any unique requirements in SAE-AMS-QQ-C-320 are complied with.【英文标准名称】:StandardTestMethodforSmokePointofKerosineandAviationTurbineFuel
