Haynes˘ 214
Haynes 214 is a Nickel-Chromium-Aluminium-Iron alloy which is principally intended for use at temperatures of 955 °C (1750 °F) and above. It exhibits resistance to oxidation that far exceeds virtually all conventional heat resistant wrought alloys at these temperatures, which is attributable to the forming of an Al2O3-type protective oxide scale, which forms in preference to Chromium Oxide scales at such high temperatures. Best suited for high temperature, low stress environments, Haynes 214 is used in the aerospace, automotive, industrial heating and medical industries, as well as for land-based gas turbines.
Haynes 214 is also known as Cabot 214 and Hastelloy 214.
Available in all profile options
