What material is Hastelloy C?

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

Hastelloy plates are suitable for various chemical industries containing oxidation and reduction media. The high content of molybdenum and chromium makes the alloy resistant to chloride ion corrosion, and tungsten further improves the corrosion resistance. At the same time, C-276 Hastelloy alloy tube is the only material that can resist the corrosion of wet chlorine, hypochlorite and chlorine dioxide solution, and has obvious corrosion resistance to high concentration chloride solutions such as ferric chloride and copper chloride.

Extended data:

Characteristics of Hastelloy;

1, which has excellent corrosion resistance to most corrosive media in oxidation and reduction atmosphere.

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

Hastelloy is mainly divided into three series: B, C and G, which are mainly used in places with strong corrosive media such as iron-based Cr-Ni or Cr-Ni-Mo stainless steel and nonmetallic materials.
