Inconel alloys

Alloys of inconel include:

  • Inconel 600: Solid solution strengthened
  • Inconel 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
