SAE AMS 5769F-2003 (SAE AMS5769F-2003)
Alloy, Corrosion and Heat-Resistant, Bars, Forgings, and Rings, 21Cr 20Ni 20Co 3.0Mo 2.5W 1.0(Cb+Ta) 0.15N 32Fe Solution Heat Treated ( Reaffirmed: May 2008 )
This specification covers a corrosion and heat resistant alloy in the form of bars, forgings, flash welded rings, and stock for forging, flash welded rings, or heading. These products have been used typically for parts, such as turbine rotors, shafts, blades, and bolts, requiring high strength up to 1350 \mDF (732 \mDC) and oxidation resistance up to 1800 \mDF (982 \mDC), but usage is not limited to such applications.
