Incoloy 901 (N09901) Nickel Based Alloy Overview:
The Cr content in Incoloy 901 nickel-based alloy is usually
11.0-14.0%, and the nickel content is 40.0-45.00%. Incoloy 901
alloy is a nickel-based alloy containing molybdenum and copper,
which has good hot and cold workability. Incoloy901 is an
austenitic age-hardening alloy based on Fe-43Ni-12Cr, adding
titanium, aluminum, and equivalent strengthening elements, and
contains a small amount of boron and lower carbon. The metastable γ
"[Ni3 (Ti, Al)] phase is dispersedly strengthened, and a small
amount of aluminum can inhibit the conversion of γ "to the η-Ni3Ti
phase.
Incoloy 901 alloy has high yield strength and long-lasting strength
below 650 ℃, good oxidation resistance below 760 ℃, and stable
structure for long-term use. This alloy is a relatively mature
alloy developed in the early days. It is widely used to manufacture
rotating discs (turbine discs, compressor discs, journals, etc.),
static structural parts, and turbines for aviation and ground gas
turbine engines operating below 650 ° C. Parts such as outer rings
and fasteners.
