AMS5743A Steel, Corrosion and Heat-Resistant, Bars and Forgings 15.5Cr - 4.5Ni - 2.9Mo - 0.10N Solution Heat Treated, Sub-Zero Cooled, Equalized, and Over-Tempered

This specification covers a corrosion and heat resistant steel in the form of bars, forgings, and forging stock.

These products have been used typically for parts requiring oxidation resistance and high strength up to 800 degrees F (427 degrees C) and where such parts may require welding during fabrication, but usage is not limited to such applications.
