It has excellent resistance to oxidation, atmospheric corrosion and stress corrosion cracking, and has high resistance to local corrosion (pitting corrosion, crevice corrosion).
Hastelloy G30 is widely used in wet phosphoric acid production

Hastelloy C2000 is a new type of Ni-Cr-Mo alloy. Compared with the traditional C4 alloy, it greatly improves its corrosion resistance in oxidizing and reducing media by increasing the chromium content and introducing copper elements. Although its intergranular corrosion resistance is slightly lower than that of C4, Hastelloy C2000 has important application value in the chemical industry and highly corrosive environments due to its wider range of protective properties.

Alloy C-276 (UNS N10276, W.Nr. 2.4819) can be used in many chemical processes with both oxidizing as well as reducing media. The highchrome and molybdenum concentrations make the alloy resistant to chloride ion attacks

Hastelloy C22 is a high nickel alloy with high chromium and molybdenum content and excellent corrosion resistance in oxidizing, reducing and oxidizing-reducing media.
Hastelloy C22 alloy has amazing resistance to various chemical environments. It cannot be corroded by strong oxidizing substances or humid hydrogen, hypochlorite and chlorine dioxide solutions. Its metallographic structure is a face-centered cubic lattice structure, which gives it the ability to resist chloride ion erosion and maintain good corrosion resistance.

Hastelloy C-4 is an austenitic low carbon nickel-molybdenum-chromium alloy. The main difference between Hastelloy C-4 and other alloys of similar chemical composition developed earlier is the low carbon, silicon, iron and tungsten content. Such chemical composition makes it show excellent stability at 650-1040℃, improves the ability to resist intergranular corrosion, and can avoid edge line corrosion sensitivity and weld heat affected zone corrosion under appropriate manufacturing conditions.

Hastelloy B-3 is a nickel-based high-temperature alloy composed of nickel, molybdenum, cobalt and other elements. The nickel content is about 65%. It is a new material improved on the basis of Hastelloy B2. It improves the thermal stability of the material, thereby enhancing the corrosion resistance, while improving the hot forming and cold forming properties. It is widely used in the production and manufacturing of chemical equipment.

Hastelloy B2 is a nickel-molybdenum alloy that is particularly suitable for handling devices in chemical environments. It is used in the chemical processing industry with sulfuric acid, phosphoric acid, hydrochloric acid and acetic acid.
