Incoloy 800/800H Fe-Ni-Cr Heat-resistant and corrosion-resistant alloy

Incoloy 800/800H is an iron-nickel-chromium based heat-resistant and corrosion-resistant alloy with a nickel content of approximately 32%. It possesses excellent high-temperature oxidation resistance, carburization resistance, and sulfidation resistance.
800: Ordinary solution-treated state, general-purpose heat and corrosion resistant.
800H: High-temperature carbon control + high-temperature annealing significantly improves high-temperature creep resistance, suitable for long-term high-temperature pressure resistance.

Advantages

Excellent high-temperature performance: Anti-oxidation, anti-carburization, and anti-sulfurization; long-term usability up to 815℃.

Good resistance to stress corrosion cracking: Resistant to chloride ion SCC, superior to 304/316.

Good machinability and weldability: Easy to cold and hot form, stable weldability.

Stable microstructure: Not prone to embrittlement during long-term use at medium and high temperatures.

High cost-effectiveness: Lower nickel content than Inconel/Hastelloy, resulting in lower cost.

Disadvantages

Moderate resistance to strong acids: Not resistant to high-concentration strong acids such as hydrochloric acid and phosphoric acid.

Medium strength: Room temperature strength is lower than 625/718/C276.

Large creep variation: 800℃ is not suitable for long-term high-temperature pressure bearing; 800H must be used.

Sensitization tendency: Intergranular corrosion may occur during long-term use in the medium temperature range.

Warehousing Management

Before each batch of steel leaves the factory, a complete process inspection is strictly carried out. From chemical composition, mechanical properties to dimensional tolerance and surface quality, each item is carefully checked to ensure compliance with national standards and export regulations. At the same time, the quantity, packaging and rust prevention treatment are also verified. An original factory warranty certificate is attached, guaranteeing the quality. Before shipment, inspection photos are provided. Any non-compliant items will not be released, and the quality is fully controllable throughout the process. This ensures your overseas purchasing is safe and worry-free.

All items are visually inspected before delivery. No cracks, deformation, rust, scratches or cutting marks are allowed; edges must be smooth. Only visually sound products will be shipped.

Thickness, width, length, wall thickness, outer diameter have been measured. Straightness, curvature, torsion, diagonal tolerance all meet the corresponding tolerance requirements.

Quality inspection includes: mechanical property tests (yield strength, tensile strength), elongation rate, impact energy, hardness testing, chemical composition testing, process performance testing, etc.

Inspection according to packaging requirements: secure binding, moisture-proof film, rust-proof paper, export fumigation/fumigation-free wooden crates, shipping marks, gross weight, net weight, etc.

We will provide full reception services to support the customers' on-site inspection of the goods.
