NCF800
Share to：
NCF800 is a high-performance nickel-based alloy, also known as Incoloy 800 or N08800. High-temperature oxidation resistance: A dense oxide film forms in high-temperature environments (such as below 1000°C), effectively resisting oxidation and carburization.

Details description
Corrosion Resistance
Excellent corrosion resistance to various media such as sulfuric acid, phosphoric acid, and nitric acid.
Strong resistance to chloride ion stress corrosion cracking (SCC) and pitting corrosion.
Processing Properties
Wide hot working temperature range (1100-950°C), good cold working performance.
Can be formed by welding (such as TIG, MIG) and machining.
Stability: Stable microstructure at high temperatures for extended periods, not prone to precipitation of harmful phases.
Product Specifications and Supply Forms
Plates/Strips: Thickness 0.5-10mm, width ≤1500mm.
Pipes: Seamless pipes (outer diameter 6-219mm, wall thickness 0.5-20mm), welded pipes.
Bars/Wires: Diameter 5-200mm, wires can be used for welding.
Forgings: Customized parts such as flanges, valves, and shafts.
Application Areas
Chemical Industry: Reactors, heat exchangers, piping systems (especially those containing sulfur media).
Energy Sector:
Nuclear power equipment (steam generators, heat exchangers).
Hydrocracking units in petrochemicals.
Heat treatment furnaces: High-temperature components such as furnace rollers, radiant tubes, and annealing tanks.
Environmental protection equipment: Incinerators, flue gas desulfurization systems.
Food processing: Containers and pipes in contact with acidic or high-temperature foods.
Instructions for Use
Welding: It is recommended to use matching nickel-based welding materials (such as ERNiCr-3). Solution treatment is required after welding to eliminate stress.
Processing: Annealing is recommended after cold working to restore corrosion resistance.
Temperature Limit: The long-term operating temperature should not exceed 1100°C. Avoid staying in the 400-700°C range to prevent embrittlement.
Comparison with Other Alloys
Compared with Inconel 600: NCF800 has a lower cost and higher iron content, suitable for non-strongly reducing environments.
Compared with 316L stainless steel: Significantly improved high-temperature and corrosion resistance, especially in high-temperature sulfur-containing environments.
Implementation Standards
International: ASTM B409 (plates), ASTM B514 (pipes), ASTM B564 (forgings).
Domestic: GB/T 15007 (NS1101), GB/T 14992 (high-temperature alloy classification).
