Product Code:SAE AMS5595
Title:Steel, Corrosion Resistant, Sheet, Strip, and Plate, 9.0Mn - 20Cr - 6.5Ni - 0.28N, Solution Heat Treated
Issuing Committee:Ams F Corrosion Heat Resistant Alloys Committee
Scope:This specification covers a corrosion-resistant steel in the form of sheet, strip, and plate.These products have been used typically for parts requiring high strength and corrosion resistance from -423 to +1100 °F (-253 to +593 °C), where such parts may require welding during fabrication, but usage is not limited to such applications.
