HASTELLOY X（UNSN06002） Bar

hastelloy x bar
Nickel-Chromium-Iron-Molybdenum Alloy for High-Temperature & Oxidation Resistance

HASTELLOY X bar is widely used for machined components requiring high-temperature strength, oxidation resistance, and good resistance to carburizing/nitriding furnace atmospheres. It also offers good stress-corrosion cracking resistance in certain petrochemical environments.

As a professional Chinese nickel-based alloy manufacturer, we supply HASTELLOY X bar with stable chemistry, consistent mechanical properties, and flexible dimensional customization for global industrial users.
