Hastelloy G3 Alloy Pipe

Hastelloy G3 alloy, referred to as G3, is a nickel-based corrosion-resistant alloy with superior performance. It belongs to the Ni-Cr-Fe system containing Mo and Cu. It has excellent resistance to oxidation, atmospheric corrosion and stress corrosion cracking, and has relatively good High resistance to local corrosion (pitting corrosion, crevice corrosion). Due to the high Fe content in the alloy, it has the characteristics of low cost compared with other nickel-based corrosion-resistant alloys. G3 alloy is commonly used in flue gas desulfurization systems, papermaking, and phosphoric acid production steam generators and heat exchangers. Oil well pipes made of this alloy have excellent resistance to H2S, CO2, and Cl- corrosion and are the best material for oil well pipes in sour gas fields. In the world, only Sumitomo of Japan, SMC of the United States, V&M of Germany and Sandvik of Sweden can produce it.
