Description
A nickel-iron-chromium alloy containing titanium and aluminum for precipitation hardening and molybdenum for solid-solution strengthening. The alloy has high yield strength and creep resistance at temperatures to about 1110°F (600°C). A subtantial iron content enables the alloy to combine high strength with good forging characteristics. Used in gas turbines for discs and shafts. Standard products form is round.
Corrosion Resistance
Alloy 901 has good corrosion resistance to the atmospheres normally found in jet engine operations. It has slightly lower scaling resistance than such alloy as Types 309 and 310 stainless steel.
