Incoloy 800H and 800HT in Chennai for Furnaces, Heaters and Reformer Parts

Incoloy 800H and 800HT in Chennai for Furnaces, Heaters and Reformer Parts

Incoloy 800H and 800HT plate and sheet for furnace, heater and reformer work in Chennai. Auto-component and commercial heat-treatment shops in Oragadam, Irungattukottai and Sriperumbudur, and heater fabricators serving process units, use 800H and 800HT for muffles, retorts, radiant tubes and fixtures that must keep their shape under load at high temperature. The two grades are often dual-certified; we confirm that per enquiry. This page splits the high-temperature 800 series out of the live Incoloy in Chennai hub, which leads with 825 for North Chennai acid service. Ganesh Metals has been a high-nickel alloy stockist, supplier and processor in Mumbai since 1992.

We provide direct door delivery to your company in Chennai. Plate and sheet are cut and packed at our Mumbai shop and supplied from our Mumbai stock to Oragadam, Irungattukottai, Sriperumbudur, Ambattur, Maraimalai Nagar or Thiruvallur. Tell us the furnace or heater temperature and atmosphere, and whether you need 800H/800HT dual certification, and we will confirm the grade before quoting.

Incoloy 800H and 800HT specifications

Incoloy 800H / 800HT (UNS N08810 / N08811, W.Nr 1.4958 / 1.4959): plate and sheet ASTM B409 / ASME SB409, bar ASTM B408, seamless pipe and tube ASTM B407, welded pipe B514, welded tube B515.

800H is defined by carbon of 0.05–0.10% and a controlled grain size; 800HT keeps a tighter aluminium-plus-titanium range of 0.85–1.20%. Dual certification to both is common; we confirm it against the MTC for each order.

Forgings and flanges: ASTM B564 / ASME SB564. Fittings: ASTM B366 (WPNIC10 / WPNIC11).

Pipe, tube and flanges: sizes confirmed per enquiry, from Mumbai stock.

Grade choice for hot parts: 800H and 800HT are chosen where creep strength and the cost of large furnace sections matter. Inconel 601 gives a tighter oxide film and is often preferred at the hottest, most cyclic end — see Inconel 601 plate in Chennai. Inconel 600 is the basic nickel-chromium grade for less demanding hot work.

Typical chemistry: Ni 30–35%, Cr 19–23%, C 0.05–0.10% (800H), iron balance. Density about 7.94 g/cm³.

Minimum properties, ASTM B409 800H plate: tensile 448 MPa, yield 172 MPa, elongation 30%. For 800H and 800HT, the grain size reported on the MTC matters as much as the strength figures.

800H and 800HT forms for furnace and heater work

Furnace hardware is mostly fabricated from flat material: muffle and retort panels, tray and fixture plates, radiant-tube supports and burner parts. We cut plate and sheet to your list, punch circles for end plates, and keep the heat number on every piece. Pipe and radiant-tube sizes are confirmed per enquiry, from Mumbai stock. Estimate weights with the metal weight calculator.

Where 800H and 800HT are used in Chennai

Auto-component heat-treatment shops in Oragadam and Irungattukottai: 800H and 800HT sheet for muffles, retorts, baskets and carburising fixtures.

Commercial heat treaters and furnace rebuilders in Sriperumbudur and Maraimalai Nagar: 800H plate for trays, grids and radiant-tube supports.

Process-heater and reformer fabricators: 800H and 800HT for hot-section panels, supports and fixtures built to the heater specification.

Furnace shops around Ambattur and Thiruvallur: 800H plate for hearth parts and hot-zone baffles that must hold shape under load.

Acid-service plate for Manali is a different job — use Incoloy 825 plate in Chennai for that duty, not 800H.

Why Chennai heat-treatment shops order 800H and 800HT from Ganesh Metals

High-nickel alloy stockist, supplier and processor in Mumbai since 1992.

The mill's original EN 10204 3.1 test certificate is passed on with every supply, with heat-number traceability.

ISO 9001:2015, ISO 14001:2015 and ISO 45001:2018 certified.

Carbon, Al+Ti and grain size on the MTC are read against your 800H or 800HT order before dispatch.

Dual certification is confirmed per enquiry, not assumed on every heat.

If 601 covers the temperature and cycle better, or if 825 is the acid-service grade you actually need, we will say so.

FAQs — Chennai

Do you supply Incoloy 800H and 800HT to Oragadam and Sriperumbudur?

Yes. We send 800H and 800HT plate, sheet and related forms to Oragadam, Irungattukottai, Sriperumbudur, Ambattur, Maraimalai Nagar and Thiruvallur, supplied from our Mumbai stock. We provide direct door delivery to your company in Chennai.

How long does delivery to Chennai take?

That depends on the transporter and route. We confirm the dispatch plan with you when the order is placed.

Can you supply 800H and 800HT dual-certified plate?

Often yes, but we confirm it per enquiry against the heat and the MTC. Tell us if the drawing requires dual certification, and we will check carbon, Al+Ti and grain size before quoting.

Incoloy 800H or Inconel 601 for a carburising furnace?

800H offers useful creep strength and is often chosen for large muffle and retort sections. 601 resists scaling very well at the hottest, most cyclic end. In carburising atmospheres both are used; tell us the temperature, atmosphere and part, and we will help you compare. See Inconel 601 plate in Chennai.

Will 800H plate come with a 3.1 certificate?

Yes. Every supply comes with the mill's original EN 10204 3.1 test certificate, and heat numbers are marked on each piece. Call +91 22 6636 2372 or WhatsApp +91 99872 73700 to discuss your use.
