We are Riddhi Siddhi Impex, a Mumbai-based supplier and stockist of Inconel 600 Sheets & Plates, established in 2002. We hold a ready stock of this nickel-chromium-iron alloy to ASTM B168 / ASME SB-168, in sheets from 0.8 mm and plates in heavier gauges, sourced from reputed primary mills. Our ISO 9001, 14001, and 45001-certified company carries a monthly supply capacity of 400-500 tonnes and ships worldwide with EN 10204 Type 3.1 / 3.2 test certificates available on request.
Inconel 600 sheets and plates are nickel-chromium-iron alloy flat products holding a minimum of 72% nickel, which makes them resistant to oxidation and corrosion at high temperatures. Its chromium lifts performance in oxidising atmospheres, and the nickel base resists chloride-ion stress corrosion cracking and caustic alkalis. Flat products serve continuously up to about 1093 °C. It is widely applied in high-performance industrial applications like heat treatment and aerospace equipment.
We stock this grade in cold-rolled sheets from 0.8 mm and hot-rolled plates in standard width sizes. Material ships annealed to ASTM B168, in 2B or BA finishes with mill test certification. Our inventory can hold up to 1000 tonnes annually.
We provide ASTM B168 Inconel 600 plate and UNS N06600 sheet in annealed condition, in two surface finishes and two edge options.

Nickel defines this grade. UNS N06600 carries 72% nickel minimum, with 14 to 17% chromium for oxidation resistance and 6 to 10% iron. The full ASTM B168 composition appears below.
| Element | Composition (%) |
|---|---|
| Nickel (Ni) | 72.0 min |
| Chromium (Cr) | 14.0 to 17.0 |
| Iron (Fe) | 6.0 to 10.0 |

These 4 industries widely use the Inconel 600 sheets and plates we supply, chosen for oxidation resistance and high-temperature strength.
Chemical plants line reactor vessels and heat exchangers with Nickel Alloy 600 plate where hot chlorides and caustic soda damage lesser metals. These Inconel sheets and plates resist chloride-ion stress corrosion cracking, which splits austenitic stainless steel.
Furnace builders form Alloy 600 sheet into muffles, retorts, radiant tubes, and fixture baskets. The grade holds strength and resists scaling in oxidising and carburising atmospheres to about 1093 °C.
Nuclear steam generators and reactor components use Inconel 600 plate for its low corrosion rate in high-purity water. The alloy pairs high-temperature strength with resistance to caustic and chloride environments.
Aerospace fabricators specify Inconel 600 sheet to AMS 5540 for exhaust systems, ducting, and turbine seal rings. The grade holds strength through repeated heating and cooling, and resists oxidation at red heat.

Inconel 600 Sheets & Plates price in India is around ₹ 2,000 to ₹3,500 per kg. For international buyers, it is generally $20 to $39 per kg. The figure moves with global nickel rates, and thickness, width, finish, and quantity shift it. Call or WhatsApp us for today's rate and volume discounts.
Inconel 600 sheets and plates are covered by ASTM B168 and its ASME equivalent SB-168, with AMS 5540 for aerospace sheets. These standards set the chemistry, mechanical minimums, and tolerances for UNS N06600.
The chemical composition of Inconel 600 sheet and plate is 72% nickel minimum, 14 to 17% chromium and 6 to 10% iron with carbon to 0.15% maximum and controlled limits on manganese, silicon, copper and sulphur.
The main difference between Inconel 600 sheet and plate is in thickness and rolling. The sheet is cold rolled to about 10 mm whereas the plate is hot rolled in 3 mm and above gauges. Both conform to ASTM B168.
We supply Inconel 600 sheets from 0.8 mm and plates in heavier gauges, in widths up to standard sizes.
Inconel 600 plates can be welded by common processes using a matching nickel-alloy filler. Joints must stay clean and free of sulphur, which the alloy won't tolerate at temperature. Fabricated plate can be stress-relieved at 982 to 1010 °C for one hour.
Yes, we supply Inconel 600 sheets and plates with EN 10204 Type 3.1 and 3.2 mill test certificates on request. Each confirms chemistry and mechanical properties with full traceability.
You can source reliable Inconel 600 Sheets from Riddhi Siddhi Impex. We keep a ready stock at our Mumbai warehouse for quick dispatch. As suppliers, stockists, and exporters, we serve buyers across India and overseas, providing quotations within 24 hours.
