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.
Workability
Hot Working
Alloy 901 is forged between 2050°F (1121°C) and 1850°F (1010°C), metal temperature. Light hot work may be continued down to 1600°F (871°C) but not below. Metal temperature should not exceed 2050°F (1121°C) during rapid working. Billets should be charged into a hot furnace and heated rapidly through the precipitation hardening range.
Weldability
Alloy 901 can be welded by the inert-gas-arc method. It is difficult to weld. All welding should be done in the solution treated condition. Cold worked parts should be re-solution treated before welding. A re-solution treatment is recommended after welding before stabilizing and aging.

HY 783 Material grades and equivalents ( for steam turbine parts )
Inconel 783 / Alloy 783 / UNS R30783
An oxidation resistant low coefficient of thermal expansion (low CTE) superalloy developed for gas turbine applications.
The alloy is strengthened by a precipitation-hardening heat treatment made possible by additions of niobium and aluminum. In addition, the aluminum content provides excellent resistance to oxidation at high temperature.
The alloy’s density is 5% less than those of superalloys such as INCONEL alloy 718. The combination of low expansion, high strength and excellent resistance to oxidation makes the alloy especially useful for gas turbine and steam turbine components.
The low expansion enables closer control of clearances and tolerances for greater power output and fuel efficiency.
