Product Code:SAE AMS5597
Title:Nickel Alloy, Corrosion and Heat Resistant, Sheet, Strip, and Plate, 52.5Ni - 19Cr - 3.0Mo - 5.1Cb (Nb) - 0.90Ti - 0.50Al - 18Fe, Consumable Electrode or Vacuum Induction Melted, 1950 掳F (1066 掳C) Solution Heat Treated
Issuing Committee:Ams F Corrosion Heat Resistant Alloys Committee
Scope:This specification covers a corrosion and heat resistant nickel alloy in the form of sheet, strip, and plate.These products have been used typically for parts, such as cases and ducts, requiring high strength at cryogenic temperatures and for short time use up to 1000 掳F (538 掳C), particularly those parts which are formed or welded and then heat treated to develop required properties, but usage is not limited to such applications.【英文标准名称】:StandardTestMethodforRadiochemicalDeterminationofUraniumIsotopesinSoilbyAlphaSpectrometry
