Product FEATURE
GH901 is an austenitic age-hardening alloy based on Fe-43Ni-12Cr, adding titanium, aluminum and other strengthening elements, and contains a trace of boron and low carbon, by the sub-stable γ [Ni3 (Ti, Al)] phase dispersion strengthening, a small amount of aluminum can inhibit γ to the conversion of η-Ni3Ti phase. The alloy has high yield strength and endurance strength below 650℃, good oxidation resistance below 760℃, and stable organization for long-term use.
Product application
This alloy is a mature alloy developed in the early days and is widely used in the manufacture of rotating disk parts (turbine disks, compressor disks, journals, etc.), static structural parts, turbine outer rings, fasteners and other parts of aviation and ground gas turbine engines operating below 650°C. The alloy is widely used in the manufacture of gas turbine engines.
