Inconel alloys
Alloys of inconel include:
- Inconel 600: Solid solution strengthened
- Inkonel 601
- Inconel 625: Acid resistant, good weldability. The LCF version is typically used in bellows.
- Inconel 690: Low cobalt content for nuclear applications, and low resistivity
- Inconel 713C: Precipitation hardenable nickel-chromium base cast alloy
- Inconel 718: Gamma double prime strengthened with good weldability
- Inconel 751: Increased aluminium content for improved rupture strength in the 1600 °F range
- Inconel 792: Increased aluminium content for improved high temperature corrosion properties, used especially in gas turbines
- Inconel 939: Gamma prime strengthened to increase weldability
