本说明书涵盖了对金属板部件（例如支架、间隔件和垫圈）提供增强的耐腐蚀性的处理的工程要求，所述金属板部件由马氏体耐腐蚀性钢（通常为AMS 5504或AMS 5508且硬度不高于40HRC）或铁素体耐腐蚀性钢（通常为AMS 5506）制成。不建议将这种处理用于在使用中受到冲击的零件。

This specification covers the engineering requirements for a treatment to provide enhanced corrosion resistance to sheet metal parts, such as brackets, spacers, and washers, fabricated from martensitic Corrosion-resistant steels, usually AMS 5504 or AMS 5508 and having hardness not higher than 40 HRC, or ferritic corrosion-resistant steels, usually AMS 5506. The treatment is not recommended for use on parts subject to impact in service.
