We are Riddhi Siddhi Impex, a Mumbai-based Incoloy 800 Strips manufacturer, supplier, and exporter, established in 2002. We slit nickel-iron-chromium Alloy 800 strip to ASTM B409 / ASME SB-409 in thicknesses from 0.03 mm to 5 mm, with its width held to ±0.1 mm. Our ISO 9001, 14001, and 45001-certified company carries ready stock and a supply capacity of 400-500 tons monthly, backed by EN 10204 Type 3.1 / 3.2 certificates on request.
Incoloy 800 strips are narrow, nickel-iron-chromium alloy slit from Incoloy coil. The chemical composition runs 30 to 35% nickel and 19 to 23% chromium over a 39.5% minimum iron balance, with small additions of aluminium and titanium that stabilise the alloy's microstructure during prolonged exposure to elevated temperatures. UNS N08800 strip resists oxidation, carburisation, and sulphidation, and it holds useful strength in continuous service to around 816 °C. Typical uses include heat exchangers, furnace components, heating element sheathing, and piping systems in petrochemical plants.
As a reputable Incoloy 800 strip supplier, we slit every Inconel strip in-house on our own lines. Strip leaves annealed to ASTM B409, with a width from 3 mm to 2000 mm, in hot rolled or cold rolled supply with the edge condition your tooling needs.
We provide ASTM B409 Incoloy 800 strips in annealed soft condition, hot rolled or cold rolled, precision slit from ready stock with a choice of finishes and four edge options.

Aluminium and titanium defines this grade. Each at 0.15 to 0.60% in UNS N08800 strip, stabilising the alloy through thermal cycling, while chromium at 19 to 23% builds the protective oxide film. The full ASTM B409 composition appears below.
| Element | Composition (%) |
|---|---|
| Nickel (Ni) | 30.0 to 35.0 |
| Chromium (Cr) | 19.0 to 23.0 |
| Iron (Fe) | 39.5 min (balance) |
| Carbon (C) | 0.10 max |
| Manganese (Mn) | 1.50 max |
| Silicon (Si) | 1.00 max |
| Copper (Cu) | 0.75 max |
| Sulphur (S) | 0.015 max |
| Aluminium (Al) | 0.15 to 0.60 |
| Titanium (Ti) | 0.15 to 0.60 |
Annealed Incoloy 800 Winding Strip pairs a 520 MPa minimum tensile strength with 30% elongation, so it forms, bends, and draws cleanly. ASTM B409 applies its yield-strength minimum only to material 0.508 mm (0.020 in) and thicker; the elongation minimum applies down to 0.25 mm (0.010 in) for cold-rolled strip. Figures for thinner slit gauges are indicative.

International buyers can cross-reference UNS N08800 strip against their regional standard below. Some enquiries name the grade Inconel 800, but the correct family name is Incoloy, since iron forms the balance.
| Country / Standard | Designation |
|---|---|
| USA (UNS) | N08800 |
| Europe (EN) | X10NiCrAlTi32-20 |
| Germany (W.Nr) | 1.4876 |
| Japan (JIS) | NCF 800 |
| United Kingdom (BS) | NA 15 |
| Russia (GOST) | XH32T |
These 4 industries specify most of our Incoloy 800 Slitting Coil. Buyers pick the grade for oxidation and carburisation resistance and for strength that survives long thermal exposure.
Chemical plants form Alloy 800 strips into reactor trim, gasket windings, and lining segments that face hot, oxidising process streams. The chromium oxide film holds off scaling, and the high nickel content resists chloride stress corrosion cracking where standard stainless steel fails early.
Power stations and nuclear fabricators specify Incoloy 800 strip for steam generator components, heating element sheathing, and control hardware. The alloy keeps its austenitic structure under prolonged heat, so parts hold their tolerance through years of thermal cycling.
Furnace builders wind Incoloy 800 Winding Strip into elements for high-heat muffles, retorts, continuous baskets, and radiant shields exposed to direct heat. The grade withstands carburising atmospheres to around 816 °C in continuous duty, and precision-slit widths drop into fixtures without secondary trimming.
Food processing lines fit Alloy 800 strip into heating hardware and hygienic equipment handling organic acids and hot cleaning cycles. The alloy resists attack from acidic media without picking up scale, so contact surfaces stay clean through repeated sanitising runs.

Incoloy 800 Strips price in India is around ₹1,350 to ₹1,800 per kg, roughly $14 to $19 per kg for export buyers. The figure tracks global nickel rates, and thickness, width, finish, edge, and quantity all move it. This range is indicative, so call or WhatsApp us for today's rate.
Incoloy 800 strips are covered by ASTM B409 / ASME SB-409, which specifies nickel-iron-chromium alloy (UNS N08800) plate, sheet, and strip. For aerospace orders, AMS 5871 applies, and we supply to whichever standard you need.
We slit Incoloy 800 strips from 0.03 mm to 5 mm thick and to any width between 3 mm and 2000 mm, held to ±0.1 mm. Gauge, width, finish, and edge follow your order.
Incoloy 800 (UNS N08800) holds carbon to 0.10% maximum with no lower limit. Incoloy 800H (UNS N08810) keeps carbon between 0.05 and 0.10% with a controlled coarse grain size, which lifts creep-rupture strength above 600 °C. Our strips ship as base grade Incoloy 800.
Yes, we precision-slit Incoloy 800 strips to any width from 3 mm to 2000 mm on our own lines, holding ±0.1 mm. Custom slitting is our core service.
Incoloy 800 strips serve continuously up to around 816 °C in oxidising and carburising atmospheres. For prolonged duty above that point, 800H or 800HT grades offer better creep and rupture strength.
You can source Incoloy 800 strips in India from us at Riddhi Siddhi Impex. Our Mumbai warehouse holds Alloy 800 strip on the shelf for immediate dispatch. As a manufacturer, stockist, and exporter, we serve buyers across India and overseas. Phone or WhatsApp us to get a quote within 24 hours.
