Haynes® Alloy 214

UNS N07214
W.Nr 2.4646

Applications

Honeycomb seals, flame hoods, burners, mesh belts, catalytic converters, Chlorine contaminated incinerator systems, and other static oxidation - limited parts

Description

Haynes® Alloy 214 is a nickel-chromium-aluminum-iron alloy with excellent high temperature corrosion and oxidation resistance at and above 955°C (1750°F). H214 is best suited for high temperature, low stress environments. Haynes® Alloy 214 is sold in the solution heat treated condition. At temperatures above 1750°F, an Al2O3 type oxide scale develops, providing excellent resistance to carburization, nitriding and corrosion in chlorine-bearing oxidizing environments.

Industries Supplied

Aerospace, Automotive, Industrial Heating, Medical Waste Disposal, and Land-Based Gas Turbines.
