Title:Treatment of Sheet Metal Parts, Corrosion-Resistant Steel (NONCURRENT)
Issuing Committee:Ams B Finishes Processes And Fluids Committee
Scope:This specification covers the enginering 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.【英文标准名称】:Copperandcopperalloys;estimationofaveragegrainsize
