Alloy 214 Description
Alloy 214 is a nickel-chromium-aluminum-iron alloy, designed to provide the optimum in high-temperatures oxidation resistance for a wrought austenitic material, while at the same time allowing for conventional forming and joining. Intended principally for use at temperatures of 1750°F and above, alloy 214 exhibits resistance to oxidation that far exceeds virtually all conventional heat-resisting wrought alloys at these temperatures. 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 temperatures. At temperatures below 1750°F, alloy 214 develops an oxide scale which is a mixture of chromium and aluminum oxides. This mixed scale is somewhat less protective, but still affords alloy 214 oxidation resistance equal to the best nickel-base alloys.
