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. 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.
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.
