C-276 (UNS N10276) Stainless Steel Applications (marketing department of Shanghai HY Industry Co., Ltd)

Hastelloy C-276 boltsUNS N10276 is a tungsten-containing nickel-chromium-molybdenum-alloy-alloy with low silicon and carbon content. The alloy has excellent corrosion resistance to most corrosive media in both oxidized and reduced states. Excellent resistance to pitting corrosion, crevice corrosion and stress corrosion cracking. Alloys are suitable for various chemical process industries containing oxidizing and reducing media. The higher content of molybdenum and chromium makes the alloy resistant to the corrosion of chloride ions, and the tungsten element also improves its corrosion resistance. Hastelloy-276 is one of only a few materials resistant to the corrosion of wet chlorine, hypochlorite, and chlorine dioxide solutions. The alloy has significant corrosion resistance to high concentrations of chloride solutions (such as ferric chloride and copper chloride).

2. UNS N10276 similar grades:

  • NS334, Alloy C-276, Hastelloy C-276, Inconel alloy C-276, W.Nr. 2.4819

3. UNS N10276 has the following characteristics

  • In oxidation and reduction state, it has excellent corrosion resistance to most corrosive media.

  • Excellent resistance to pitting corrosion, crevice corrosion and stress corrosion cracking.

4. Application areas of C-276 (UNS N10276)

  • It has been widely used in chemical and petrochemical fields, such as components and catalytic systems in contact with chloride-containing organics. This material is especially suitable for use in high temperature, inorganic and organic acids mixed with impurities (such as formic acid and acetic acid), and seawater corrosive environments.

5. Other fields of application:

  • Pulp and paper industry, such as digestion and bleaching vessels

  • Scrubbers, reheaters, wet steam fans, etc. in FGD systems

  • Equipment and components operating in sour gas environment

  • A reactor for acetic acid and acidic products

  • Sulfuric acid condenser

  • Methylene diphenyl isocyanate (MDI)

  • Production and processing of impure phosphoric acid

6. Alloy C-276 stainless steel plate cold working method:

  • water cutting Alloy C-276 thick plate – often slow.

  • Cutting Alloy C-276 medium plate by shearing plate – its forming quality is generally high, but the efficiency is low.

  • Alloy C-276 steel plate processed by punching machine – often cannot meet the needs of mass production.

  • Drilling and processing Alloy C-276 steel strip – often can not meet the needs of mass production.

7. Alloy C-276 combined steel plate hot working method:

  • Plasma cutting Alloy C-276 board – plasma cutting speed is fast, high efficiency, but the cutting quality is poor. Laser Cut Alloy C-276 Tape – Both methods can be applied to profile cutting requirements for bonded steel sheets.
