INCOLOY 800/H（UNSN08810） WIRE

incoloy 800 800h wire
Nickel-Iron-Chromium alloy for high-temperature oxidation and carburization resistance

INCOLOY 800/H wire is supplied for corrosion-resistant fasteners, springs, woven mesh, and also as welding wire/filler applications where compatibility with C-22 base metal is required. The alloy maintains excellent corrosion resistance in both oxidizing and reducing environments and is suitable for demanding chemical process and pollution-control services.

As a professional Chinese nickel-based alloy manufacturer, we supply INCOLOY 800/H in multiple product forms with stable chemistry, consistent mechanical properties, and flexible dimensional customization for global industrial users.

Key Characteristics

• Excellent resistance to pitting and crevice corrosion in chloride media
• Outstanding resistance to chloride stress corrosion cracking (SCC)
• Strong resistance to oxidizing and reducing acids in mixed process media
• Withstands wet chlorine gas, hypochlorite, and chlorine dioxide solutions
• High chromium content improves resistance to oxidizing media; suitable for use in the as-welded condition
• Good fabrication and welding performance for CPI equipment
