Products Description
Lork Group high-quality Haynes 214 alloy (UNS N07214) is a nickel - chromium-aluminum-iron alloy, designed to provide the optimum in high-temperature oxidation resistance for a wrought austenitic material, while at the same time allowing for conventional forming and joining. Pincipally 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.
This is attributable to the formation of a tightly adherent Al2O3-type protective oxide scale, which forms in preference to chromium oxide scales at these high temperatures. At temperatures below 1750°F (955°C), Haynes 214 alloy develops an oxide scale which is a mixture of chromium and aluminum oxides. This mixed scale is somewhat less protective, but still affords Haynes 214 alloy oxidation resistance equal to the best nickel-base alloys. The higher temperature Al2O3 - type scale which Haynes 214 alloy forms also provides the alloy with excellent resistance to carburization, nitriding and corrosion in chlorine-bearing oxidizing environments.
