① In oxidizing and reducing atmospheres, it has excellent corrosion resistance and can resist the erosion of most corrosive media.

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

Classification and application

HastelloyB is a strongly reducing media corrosion resistant alloy used in hot concentrated hydrochloric acid and hydrogen devices and components.

HastelloyB-2 has a face-centered cubic crystal structure. By controlling the iron and chromium content to a minimum, it reduces processing brittleness and prevents Ni4Mo phase precipitation between 700°C and 870°C. It is mainly used in the chemical industry, petrochemical, energy, manufacturing and pollution control fields. .

HastelloyC-4 is a chlorine-resistant composite redox ion etching structure and good thermal stability alloy. Appliances used for wet chlorine, hypochlorous acid, sulfuric acid, hydrochloric acid, and mixed acid chloride can be directly coated after welding.

HastelloyC-22 is a high molybdenum, tungsten and chromium alloy. It is widely used in industries such as chemistry and petrochemicals that contain chemical properties of oxidation and reduction processes.

HastelloyC-276 has excellent pitting corrosion resistance, uniform corrosion resistance, intergranular corrosion resistance and good high temperature mechanical properties. It is mainly used in nuclear industry, chemical industry, petroleum, non-ferrous metallurgy and other industries.
