Hastelloy is a nickel-based corrosion-resistant alloy, mainly divided into two categories: nickel-chromium alloy and nickel-chromium-molybdenum alloy. Hastelloy has good corrosion resistance and thermal stability, and is mostly used in aviation, chemical fields, etc.

Hastelloy grades include the following grades:

HASTELLOY B-2 nickel-molybdenum alloy with excellent corrosion resistance in reducing environments

HASTELLOY B-3 The upgraded version of B-2 has excellent corrosion resistance to hydrochloric acid at any temperature and concentration.

HASTELLOY C-4 has good thermal stability, good toughness and corrosion resistance at 650-1040 degrees Celsius.

HASTELLOY C-22 has better resistance to uniform corrosion in oxidizing media than C-4 and C-276, and has excellent resistance to localized corrosion.

PRODUCT APPLICATION

Hastelloy plates are suitable for various chemical industries containing oxidizing and reducing media. The higher molybdenum and chromium content makes the alloy resistant to chloride ion corrosion, and the tungsten element further improves the corrosion resistance. At the same time, C-276 Hastelloy pipe is one of the only materials that is resistant to corrosion by moist chlorine, hypochlorite and chlorine dioxide solutions, and is resistant to high-concentration chloride solutions such as ferric chloride and copper chloride. Remarkable corrosion resistance.

Application areas, heat exchangers, bellows compensators, chemical equipment, flue gas desulfurization and denitrification, paper industry, aerospace applications, acidic environment.
