HASTELLOY X（UNSN06002） COIL/STRIP
Nickel-Chromium-Iron-Molybdenum Alloy for High-Temperature & Oxidation Resistance
HASTELLOY X strip is used for high-temperature components requiring oxidation resistance and good fabricability, including furnace internals, baffles, and honeycomb structures. Strip is commonly supplied in coils for slitting, stamping, and forming.
As a professional Chinese nickel-based alloy manufacturer, we supply HASTELLOY X strip with stable chemistry, consistent mechanical properties, and flexible dimensional customization for global industrial users.
Typical supply range (custom sizes and tolerances available upon request):
