Incoloy 800, 800H & 800HT Plates, Pipes, Tubes & Bars

Incoloy 800, 800H & 800HT – Stockist, Supplier and Processor in Mumbai Since 1992

Incoloy 800 (UNS N08800, W.Nr 1.4876), 800H (UNS N08810, W.Nr 1.4958) and 800HT (UNS N08811, W.Nr 1.4959) are iron-nickel-chromium alloys for high-temperature strength and resistance to oxidation and carburisation. 800H controls carbon and grain size for creep-rupture strength, and 800HT tightens aluminium and titanium further for service above about 700 °C. As a stockist, supplier and processor in Mumbai since 1992, Ganesh Metals supplies these grades as plate and sheet to ASTM B409, bar to ASTM B408, seamless pipe and tube to ASTM B407 and fittings to ASTM B366, with EN 10204 3.1 MTCs and heat-number traceability.

The three variants look alike but are not interchangeable. Alloy 800 suits service below about 600 °C; 800H and 800HT are specified for creep-governed design in furnaces, petrochemical heaters and pigtails. Many mills certify 800H/800HT together, so check which designation your design code and drawing call for, and we will match the MTC to it.

Why Choose Incoloy 800H?

The Incoloy 800 family offers good strength at high temperature, resistance to oxidation, carburisation and sulphidation, and good metallurgical stability over long exposure. With less nickel than Inconel grades, it is often the economical choice for hot, dry gas service.

Applications:

Incoloy 800H and 800HT are specified for long-term hot service where creep strength drives the design.

Petrochemical: Reformer and cracker pigtails, outlet manifolds and heater tubes in hydrogen and syngas plants.
Heat Exchangers: High-temperature exchanger tubes and superheater parts in process and power plants.
Chemical Processing: Hot reaction vessels and piping in carburising and oxidising atmospheres.
Thermal Processing: Furnace components, radiant tubes and retorts that run hot for long periods.
Power Generation: Steam generator and superheater tubing where creep strength is required.

Incoloy 800, 800H and 800HT are supplied as plates and sheets, seamless and welded pipes and tubes, round bars, flanges and fittings. Sizes on request – specify the exact designation and dimensions.

Incoloy 800H: Specs, Sizes & Equivalents

For Incoloy 800H and 800HT, the MTC must show carbon, aluminium plus titanium and grain size to prove the designation. We check these values against your specification before dispatch, and pipes and plates keep their original mill markings and heat numbers throughout.

Typical Incoloy 800H Chemistry & Properties

Typical: Ni 30–35, Cr 19–23, Fe 39.5 min
Typical: 800H carbon 0.05–0.10% with coarse grain; 800HT Al+Ti 0.85–1.20%; density about 7.94 g/cm³.
Typical use: 800 below about 600 °C; 800H/800HT for creep-governed service above that range.

FAQ: What is the difference between 800H and 800HT?

800HT has tighter Al+Ti for better creep strength.
Q: Which spec covers 800H seamless pipe? A: ASTM B407 / ASME SB407, with MTC showing carbon and grain size.
Q: Can 800H/800HT be dual-certified? A: Often yes; we confirm the exact designation on the MTC before dispatch.
