Haynes 214 is a Nickel-Chromium-Aluminium-Iron alloy which is principally intended for use at temperatures of 955oC (1750oF) and above. It exhibits resistance to oxidation that far exceeds virtually all conventional heat resistant wrought alloys at these temperatures.
Haynes 214 is also known as Cabot 214 and Hastelloy 214.
