What Are Inconel Sheets & Plates?
Inconel is a registered family of austenitic nickel-chromium-based superalloys developed for service in extreme environments high temperature, high pressure, and highly corrosive. Inconel sheets and plates are flat-rolled products used as the base material for fabricated components in heat exchangers, pressure vessels, furnace linings, combustion chambers, and chemical processing equipment.

Inconel 600 Sheets & Plates
Inconel 600 (UNS N06600 / Werkstoff Nr. 2.4816) offers excellent resistance to oxidation and carburisation at temperatures up to 1,177 °C, combined with good alkaline corrosion resistance. It is widely used in heat treatment equipment, chemical processing, and nuclear reactors. Our Inconel 600 sheets and plates are stocked in a wide range of sizes.
Inconel 601 Sheets & Plates
Inconel 601 (UNS N06601 / Werkstoff Nr. 2.4851) adds aluminium to the nickel-chromium base, producing a particularly tough alumina surface oxide that resists oxidation and scaling up to 1,250 °C. It is the preferred grade for industrial furnace components, radiant tubes, and thermal processing equipment. See our Inconel 601 sheets and plates.
Inconel 625 Sheets & Plates
Inconel 625 (UNS N06625 / Werkstoff Nr. 2.4856) is the most versatile grade — a nickel-chromium-molybdenum-niobium alloy with exceptional fatigue strength, sea-water corrosion resistance, and weldability. It is specified for marine, aerospace, chemical processing, and oil & gas applications. Our Inconel 625 sheets and plates are our most popular Inconel flat product.
Inconel 718 Sheets & Plates
Inconel 718 (UNS N07718 / Werkstoff Nr. 2.4668) is a precipitation-hardenable nickel-chromium alloy with outstanding high-temperature strength and creep resistance up to 704 °C. It is the most widely used superalloy for aerospace gas turbine components, nuclear fuel element spacers, and high-strength fastener blanks.
Incoloy 800, 800H/HT & 825 Sheets & Plates
We also supply Incoloy 800 (UNS N08800), Incoloy 800H/HT (UNS N08810), and Incoloy 825 (UNS N08825) sheets and plates under ASTM/ASME SB 424 and SB 443. These iron-nickel-chromium alloys combine good high-temperature strength with excellent carburisation and oxidation resistance, used in ethylene cracking furnaces, heat exchangers, and pressure vessels.

Where Inconel Sheets & Plates Are Specified
Aerospace & Defence Inconel 625 and 718 sheets are essential for aircraft skin panels, engine exhaust systems, nacelles, thrust reversers, and combustion liners — wherever high strength at elevated temperature plus fatigue and corrosion resistance are simultaneously required. Inconel 718 plate in precipitation-hardened condition is the go-to for airframe fastener blanks and turbine disk forgings.
Chemical Processing Inconel 600 and 625 plates line reactor vessels, heat exchanger shells, and column internals handling strong acids, caustic solutions, and chlorinated process streams. Their resistance to stress-corrosion cracking in chloride environments gives them a decisive advantage over stainless steel.
Oil & Gas / Petrochemical Offshore platform risers, subsea manifold liners, and sour-gas (H₂S) service pressure vessel cladding use Inconel 625 plates. Complement plate orders with our Inconel 625 pipe fittings and Inconel 625 tube fittings.
Heat Treatment & Industrial Furnaces Inconel 600 and 601 are the standard materials for radiant tubes, muffle furnaces, retort furnaces, and annealing box covers — applications demanding continuous operation above 1,000 °C with minimal distortion and scaling.
Power Generation Inconel alloy sheets are used in gas turbine combustion chambers, superheater tubes, heat exchanger plates in combined-cycle plants, and nuclear reactor fuel element spacers.
Marine & Seawater Service Inconel 625 has exceptional resistance to seawater pitting and crevice corrosion, making it the material of choice for marine riser systems, propeller blades, offshore mooring components, and desalination plant equipment.
Pharmaceutical & Food Processing Inconel 600 and 625 are used in autoclaves, sterilisation vessels, and reaction vessels where product purity, corrosion resistance, and cleanability are all critical requirements.
Inconel Sheets and Plates Price
The price of Inconel sheets and plates depends on factors such as alloy grade, thickness, dimensions, surface finish, material origin, quantity, certification and current nickel market conditions. Grades such as Inconel 600, 601, 625, 718 and X-750 may have different pricing based on their chemical composition and manufacturing requirements. For accurate and current Inconel sheets and plates prices, customers can contact us with their required grade, size, thickness and quantity to receive a customized quotation.
