Incoloy alloy is made up of different grades, which are produced following all ASME, ASTM, and API standards. The Incoloy 800HT Plate is made with high concentrations of nickel, chromium, and molybdenum in their concentrations. These plates show excellent resistance against corrosion, oxidation, sulfidation, and carburization. The Alloy 800HT Plate is designed with excellent mechanical properties. These plates possess a minimum tensile strength of 500Mpa and a minimum yield strength of 200Mpa. They can be elongated by 30-35% and still possess excellent workability. The 800HT Plate is highly versatile and widely used in thermal processing systems, petroleum refining, thermal power plants, chemical industries, petrochemical processing, etc. We are amongst the leading Incoloy 800HT Plate suppliers in Mumbai. Our mission is to supply high-quality products at the most reasonable rates.
The Sheet Alloy 800ht is designed with a density of 8.47 g/cm3. These alloys possess enhanced creep and rupture resistance properties. They can easily suffice in high temperatures up to 600 degrees C. The ASTM B409 UNS N08811 can be easily machined by standard procedures and is employed widely in sulfur-reducing environments. They show good resistance in aqueous conditions at moderate temperatures. ASME SB 409 UNS N08811 is very ductile and needs to be annealed for services, which are below the temperatures of 110 degrees F. They are easy to maintain and have a long service life. All our products including, the DIN 1.4959 Strips can be easily customized in different sizes, shapes, and chemical compositions as per your requirements.
The UNS N08811 Coils are manufactured with superior strength. These coils are available in thicknesses between 0.2mm to 5 mm and a width of 3.2mm to 1500mm. They can be availed in cut, beveled, polished, and plain tubing ends as per your requirements. Incoloy Alloy 800HT Shim Stock is used in various industrial systems to fill gaps between apparatus and provide structural support to the entire system. All our products are produced following all international and national standards. If you have any questions or want to get a quote on our products, contact us.

#1 Incoloy 800HT Plate–Hot rolled annealed and descaled. It is available in strip, foil and ribbon. It is used for applications where a smooth decorative finish is not required.
#2D Incoloy 800HT Plate–Dull finish produced by cold rolling, annealing and descaling. Used for deep drawn parts and those parts that need to retain lubricants in the forming process.
#2B Incoloy 800HT Plate–Smooth finish produced by cold rolling, annealing and descaling. A light cold rolling pass is added after anneal with polished rolls giving it a brighter finish than 2D.
#BA Incoloy 800HT Plate-Bright annealed cold rolled and bright annealed
#CBA Incoloy 800HT Plate-Course bright annealed cold rolled matte finish and bright anneal
#2 Incoloy 800HT Plate-Cold Rolled
#2BA Incoloy 800HT Plate–Smooth finish produced by cold rolling and bright annealing. A light pass using highly polished rolls produces a glossy finish. A 2BA finish may be used for lightly formed applications where a glossy finish is desired in the formed part.
Polished-Various grit finish for specific polish finished requirements.
