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.
Applications include:
- Mesh Belts
- Trays and Fixtures for the Firing of Pottery and China
- The Heat Treatment of Electronic Devices and
Technical Grade Ceramics
