Alpha Nickel

Inconel Fasteners Manufacturer, Supplier In Mumbai India

Alpha Overseas is a top producer of Inconel/ Incoloy fasteners in India, offering a vast selection in different sizes, grades, and weights. Due to its excellent thermal stability, Inconel may be employed in operating temperatures from cryogenic to 2200°F (982°C).

Inconel fasteners are quickly produced and machined, have high mechanical strength, and exhibit strong resistance to aqueous corrosion. The nickel-chromium-molybdenum alloy family that makes up Inconel fasteners is known for its robust strength at high temperatures and excellent corrosion resistance. Equipment for handling abiotic acid is used in producing paper pulp, and applications include heaters, stills, bubble towers, and condensers for processing fatty acids; evaporator tubes, tube sheets, and flaking trays for the synthesis of sodium sulfide. Fasteners are made from pure grade and premium Inconel Fasteners, accompanied by the correct documentation. In addition, these commonly designed alloy fasteners have excellent heat and corrosion resistance.

Table Of Contents

Like the Inconel grades, the Incoloy grade alloys feature nickel and chromium as their main essential components. The chemical makeup of the two alloy types is the only distinction. While Incoloy not only includes less than 50% nickel but also contains iron in its alloys, Inconel has almost more than 50% nickel in its alloys.

What are the characteristics of these Inconel / Incoloy Fasteners?

Fasteners with tight tolerances and outstanding finishes are guaranteed to be torque-free and error-free, thanks to precision machining and design. These Inconel fasteners have exceptional strength, dependability, and durability. These Incoloy fasteners are used with metals susceptible to corrosion and need cathodic protection. It is resistant to chloride-ion stress corrosion cracking, corrosion to organic and inorganic chemicals, and good oxidation resistance at high temperatures. The Inconel/ Incoloy fasteners should be adequately relieved before use to prevent stress corrosion cracking.
