Product Code:SAE AMS5548
Title:Steel, Corrosion and Heat Resistant, Sheet and Strip 16.5Cr 4.5Ni 2.9Mo 0.10N, 1850 to 1975 deg F (1010 to 1079 deg C), Annealed
Issuing Committee:Ams F Corrosion Heat Resistant Alloys Committee
Scope: This specification covers a corrosion and heat resistant steel in the form of sheet and strip. These products have been used typically for parts requiring high strength and oxidation resistance up to 800 degrees F (427 degrees C) and where such parts require maximum formability and may require welding during fabrication, but usage is not limted to such applications. Such parts usually require re-annealing before precipitation hardening. Alloy: AM-350 UNS Number: S35000【英文标准名称】:StandardTestMethodforInorganicChloridesandSulfatesinInsulatingOils
