N08810 is medium-carbon coarse-grain Fe-Ni-Cr austenitic heat-resistant alloy bright bar, upgraded version of N08800. Controlled minimum carbon 0.05% + coarse grain solution treatment drastically improve creep rupture strength 600~980℃ for high-pressure high-temperature service, single-phase non-magnetic FCC matrix, non-age-hardenable.

Chemical element content (%)

Specification：1.00~300.00mm

Application:It is mainly used to manufacture high-temperature radiant tubes for hydrogen reformers, pressure core rods for ethylene cracking furnaces, header bolts for power boiler superheaters above 600℃, load-bearing flanges for waste incineration high-temperature dry flues, internal heat exchange pins for solar thermal power stations, high-pressure fasteners for chloride-free dry heat petrochemical reactors, high-temperature fresh water pump shafts, load-bearing tool bars for carburizing/nitriding furnaces, gas hot air circulation high-temperature valve bodies, standard parts for large hot steam pipelines, etc.
Widely applied in complete coal-to-hydrogen chemical plants, petrochemical cracking facilities, ultra-supercritical thermal power units, waste heat incineration high-temperature flue systems, solar thermal medium-temperature dry heat exchange equipment, industrial carburizing furnaces, civil high-temperature steam circulating machinery and complete high-temperature drying environmental protection equipment industries.

Core Advantages Over Competitors

1. High quality stability: Full closed-loop production with dual spectral & metallographic inspection strictly control C, Cr, Ni, Al, Ti and balance carbon range 0.05~0.10%. Uniform coarse grain after solution treatment delivers consistent creep strength for mass production of cracking furnace & boiler high-pressure components.

2. Excellent surface quality: High-precision cold drawing & centerless grinding bars free of scale, scratches and pits. Uniform chip breaking during turning in soft annealed state eliminates secondary polishing for simple parts.

3. Ultra-high dimensional accuracy: Precision rolling mills & automatic online dimension detectors narrow tolerance band with tiny single-bar deviation and high batch uniformity, unifying component sizes in automatic mass production to raise finished yield.

4. Rich product variety: According to market demand and customer's special requirements, customized products are provided to meet the use requirements under various complex working conditions, providing customers with more choices.

5. Perfect after-sales service: The perfect after-sales service system can respond to customer needs and feedback in a timely manner. For problems encountered by customers during use, technical support and solutions are provided to customers quickly.
