Hastelloy C276 Flanges

UNS N10276 Flange, DIN 2.4819 Flanges

We are Manufacturer, Supplier & Exporter of Hastelloy C276 Flanges that are well-known as 'Superalloys' because they are manufactured using Nickel-Chromium-Molybdenum base alloyed with Tungsten and Cobalt, supplied in annealed condition for better fabricability. Hastelloy Alloy C276 Flanges are used in sour gas applications. The waste treated in these businesses is sometimes exceedingly hazardous, necessitating Hastelloy C276 Slip On Flanges that can tolerate the toxicity. All typical methods of welding Hastelloy C276 Blind Raised Flanges can be used, with the exception of the oxyacetylene and submerged arc procedures, which are not suggested when the fabricated item will be used in corrosive service. Hastelloy C276 Flanges are extremely durable and come in the highest grade and standard available.

Every raw material utilized in the manufacturing process is thoroughly tested and inspected, and a quality certificate is issued for these products. They are packaged in hardwood containers or crates to protect them from damage and rust. The low carbon content of these Hastelloy C276 Threaded Flanges (UNS N10276) reduces carbide precipitation during welding, ensuring corrosion resistance in as-welded constructions. Hastelloy C276 Slip On Flanges can be cold worked using any traditional process.
