Corrosion resistance

Hastelloy C-276 alloy tube has excellent corrosion resistance to most corrosive media in both oxidizing and reducing atmospheres. The higher molybdenum and chromium content of Hastelloy C-276 alloy tube makes the alloy resistant to chloride ion corrosion, and the tungsten element further improves the corrosion resistance. At the same time, Hastelloy C-276 is one of the only materials that can resist corrosion from moist chlorine, hypochlorite and chlorine dioxide solutions, and has significant corrosion resistance to high-concentration chloride solutions such as ferric chloride and cupric chloride. In addition, Hastelloy C-276 alloy tube reduces the content of carbon and silicon, which can control the outflow of carbides in the heat-affected part, thereby better improving its corrosion resistance.

Other properties

Hastelloy C-276 alloy tube has excellent resistance to pitting, crevice corrosion and stress cracking corrosion, is clean, has high finish and good welding performance.

Application areas

Chemical and petrochemical fields

Hastelloy C-276 alloy pipes are widely used in the chemical and petrochemical fields, such as components and catalytic systems that come into contact with chloride-containing organic matter. This material is particularly suitable for use in high temperature, inorganic and organic acids mixed with impurities (such as formic acid and acetic acid), and seawater corrosion environments.

Other fields

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

Equipment and components operating in acidic gas environments.

Reactors for acetic acid and acidic products.
