SAE AMS 5521J

This specification covers a corrosion and heat resistant steel in the form of sheet, strip, and plate.These products have been used typically for parts requiring both corrosion and heat resistance, especially where such parts may require welding during fabrication, and for parts requiring oxidation resistance up to 2000 mDF (1093 mDC) but useful at the higher temperatures only when stresses are very low, but usage is not limited to such applications.

This product replaces:SAE AMS 5521H - Steel, Corrosion and Heat Resistant, Sheet, Strip, and Plate 25Cr 20Ni (SAE 3031S) Solution Heat Treated
