Hastelloy C-22 Bar

Hastelloy C22 alloy is a versatile nickel-chromium-molybdenum-tungsten alloy that has better overall corrosion resistance than other existing nickel-chromium-molybdenum alloys, including Hastelloy C276, C4 alloy, and 625 alloys. Hastelloy C22 alloy has good resistance to pitting corrosion, crevice corrosion, and stress corrosion cracking. It has excellent resistance to oxidizing aqueous media, including wet chlorine, nitric acid, or mixed acids containing chloride ion oxidizing acids.

Application Scenario

Hastelloy C-22 bar is widely used in the following aspects. Acetic acid/acetic anhydride, acid leaching, cellophane manufacturing, chlorination systems, complex mixed acids, rollers for galvanized tanks, expansion bellows, flue gas cleaner systems, geothermal wells, hydrogen fluoride furnace cleaners, incineration cleaner systems, nuclear fuel Regeneration, pesticide production, phosphoric acid production, pickling systems, plate heat exchangers, selective filtration systems, sulfur dioxide cooling towers, sulfonation systems, tubular heat exchangers, cladding valves, etc.Other application fields of Hastelloy C22 alloy bar is suitable for various chemical process industries containing oxidizing and reducing media. The higher molybdenum and chromium content makes the alloy resistant to chloride ion erosion, and the tungsten element further improves its corrosion resistance. Hastelloy C22 is one of the only materials that is resistant to corrosion by wet chlorine, hypochlorite and chlorine dioxide solutions. Hastelloy C22 alloy has significant corrosion resistance to high-concentration chloride salt solutions (such as ferric chloride and copper chloride).

Production Process

The manufacturing process of stainless steel and alloys involves multiple steps to transform raw materials into flat,rectangular sheets or plates made of stainless steel and alloys. Here are a few key steps for stainless steel and alloys:

  • Casting

    Casting

    Molten stainless steel and alloys are cast into large ingots or billets through a casting process.

  • Hot rolling

    Hot rolling

    During the hot rolling process,the thickness of the steel ingot is gradually reduced and elongated to form long strips or coils.

  • Annealing

    Annealing

    Annealing involves heating stainless steel and alloys to a specific temperature and then slowly cooling it.

  • Cold rolling

    Cold rolling

    Cold rolling is carried out through rolling mills to reduce thickness to meet customer specifications.
