Alloy X Nickel Sheet

Corrosion resistance similar to high nickel alloys.


Alloy X is a nickel-chromium-iron-molybdenum and non-magnetic alloy.

Alloy X offers outstanding oxidation resistance and high temperature strength.


Alloy X is a nickel-chromium-iron-molybdenum and non-magnetic alloy. The high chromium, molybdenum and nickel content in this sheet product exhibits corrosion resistance levels similar to high nickel alloys, which find use in corrosion-resistant applications. The material may be welded using standard welding methods when using a matching filler.


Corrosion Resistance

Alloy X also benefits from good resistance to chloride stress-corrosion cracking and carburising atmospheres. Alloy X is often known under the trade names Haynes® X and ATI® HX. Applications for Alloy X include turbine exhausts, aircraft engines and gas turbines.
