> Ni-Fe-Cr alloy for turbine discs and rings with balanced creep strength and forgeability.

Nimonic 901 is a nickel-iron-chromium alloy designed for gas turbine discs and rings requiring high creep strength combined with good forgeability. The controlled Ti+Al content provides precipitation hardening while the balanced Ni-Fe ratio ensures good hot workability for forging operations.

## Key features

- Balanced creep strength + forgeability
- Precipitation-hardenable
- Good hot workability
- Turbine disc qualified
- Ni-Fe-Cr base for cost efficiency

## Applications

- Gas turbine compressor discs
- Turbine spacer rings
- Aircraft engine shafts
- Industrial turbine rotors
- High-temperature forgings

## Standards

- ASTM B637
- BS HR 53
- AMS 5660
