Incoloy 800 Seamless Tubes & Pipes: High-Temperature Stability for Corrosive and Oxidizing Environments
Incoloy 800 Tubes and Pipes are premium nickel-iron-chromium alloys engineered to thrive in extreme thermal and corrosive conditions. Comprising 30-35% nickel, 19-23% chromium, and 0.15-0.6% aluminum/titanium, Incoloy 800 excels in resisting oxidation, carburization, and sulfurization at temperatures up to 815°C. Its balanced composition ensures exceptional creep strength (180 MPa at 600°C) and resistance to chloride-induced stress corrosion cracking (SCC), outperforming standard stainless steels in aggressive media like nitric acid and molten salts. Manufactured to ASTM B407 and B163 specifications, these tubes are cold-worked and solution-annealed to achieve optimal grain structure for high-pressure applications. From petrochemical crackers to nuclear steam generators, Incoloy 800 Tubing delivers unmatched reliability in cyclic thermal environments.

Key Applications of Incoloy 800 Tubing
Petrochemical: Ethylene cracking furnace tubes, reformer manifolds, and syngas reactors.
Power Generation: Superheater tubes, boiler components, and coal gasification systems.
Nuclear: Steam generator tubing and heat exchangers in pressurized water reactors (PWRs).
Heat Treatment: Radiant tubes, muffles, and annealing covers for continuous furnaces.
Chemical Processing: Nitric acid condensers and urea production equipment.
Incoloy 800 Tubes & Pipes: Frequently Asked Questions
Q1: How does Incoloy 800 compare to Incoloy 825 in sulfuric acid environments?
A: While both resist sulfuric acid, Incoloy 800’s lower molybdenum content makes it more cost-effective for moderate acid concentrations (<40%) at temperatures below 100°C.
Q2: Can Incoloy 800 Tubing withstand cyclic thermal stress in furnaces?
A: Yes. Its high nickel content minimizes thermal fatigue, with proven performance in 1,000+ thermal cycles at 750°C (per ASTM E606 testing).
Q3: What welding techniques are optimal for Incoloy 800 Pipes?
A: Use AWS A5.14 ERNiCr-3 filler wire with TIG welding. Post-weld annealing at 980°C eliminates sensitization risks.
Q4: Are thin-walled Incoloy 800 Tubes suitable for high-pressure steam?
A: Our cold-drawn tubes achieve wall tolerance of ±5% and surface finish Ra ≤1.6 μm, rated for 35 MPa at 550°C (ASME BPVC Section II compliant).
Q5: Does Incoloy 800 resist carburization in hydrocarbon processing?
A: Yes. Its chromium-aluminum oxide layer reduces carburization rates by 70% compared to 304H stainless steel in cracking furnace environments.
