Incoloy 800 Round Bars are produced from a nickel-iron-chromium alloy specifically designed to resist oxidation, carburization, and many forms of corrosion at elevated temperatures. The alloy features a chemical composition typically containing 30–35% nickel, 19–23% chromium, and the balance iron, with regulated amounts of aluminum and titanium. Its molecular structure ensures stability under thermal stress, making it ideal for high-temperature service. According to standard data, the density is about 7.94 g/cm³ and the melting point ranges between 1357–1385 °C.

The specification for these bars conforms to the widely used ASTM B408 / ASME SB408 standard, and the alloy corresponds to the grade UNS N08800 / WERKSTOFF No. 1.4876. This is sometimes referred to in different countries by equivalent designations — for instance, in Europe it may be known as X10NiCrAlTi32-20 (EN standard), in Germany by Werkstoff number 1.4876, in Russia as ЭИ670, in Britain by NA 15, and in Japan as NCF 800.

The advantages of Incoloy 800 Round Bars are significant. First, thermal stability: even under continuous exposure to 700–800°C, the alloy retains its mechanical strength, resists creep, and avoids embrittlement. Second, exceptional oxidation and carburization resistance thanks to its chromium and nickel content, which helps maintain integrity in furnace and petrochemical environments.

Third, general corrosion resistance: the alloy resists stress-corrosion cracking in many aqueous media and shows strong performance even in nitric acid (up to ~70%) and certain organic acids. Fourth, the composition allows good tensile strength (≈ 520 MPa, i.e., ~ 75 ksi) and a yield strength around 205 MPa (0.2% offset), with elongation of about 30%. Finally, it offers a robust balance of manufacturability — it is workable, weldable, and can be cold-drawn, ground, or polished into various finishes.

In real-world use, Incoloy 800 Round Bars are highly valued across industries. Key uses and applications include:

• Heat-treating equipment: Incoloy 800 Round Bars are used in trays, baskets, and fixtures inside industrial furnaces where high temperature and oxidation resistance are critical.

• Petrochemical furnaces: Inco 800 bars serve in pigtails, header tubes, and cracker furnace components exposed to high thermal stress and carburizing atmospheres.

• Power generation: Used in boilers, heat exchangers, and pressure vessels that operate at elevated temperatures and require creep strength.

• Chemical processing: A key material for parts in nitric-acid environments or in non-oxidizing/corrosive salt media because of its stress-corrosion resistance.

• Electrical heating elements: As a sheath material around heating rods, Incoloy 800 bars protect heating elements from oxidation and carburization.

• Food-processing and domestic appliances: Due to its resistance to oxidation and high temperature, this alloy is used in heating or processing systems in food industry.
