Hastelloy alloy G3 alloy's main components include nickel, chromium, iron, molybdenum and copper, a combination that gives it excellent corrosion resistance, especially to oxidizing and non-oxidizing solutions. Specifically, nickel provides excellent ductility and resistance to alkaline solutions; while chromium enhances resistance to oxidizing solutions (such as nitric acid and chromic acid) and localized corrosion (such as pitting, crevice corrosion). Molybdenum and tungsten further enhance resistance to oxidizing solutions, and copper enhances resistance to non-oxidizing solutions.

Hastelloy G3 alloy performs well in a variety of industrial applications. It is commonly used in flue gas desulfurization systems, papermaking, phosphoric acid production steam generators and heat exchangers. In these applications, G3 alloy can effectively resist environments containing corrosive substances such as chlorine, hydrogen sulfide and carbon dioxide. For example, in the field of oil and gas extraction, G3 alloy is widely used to manufacture oil well pipes because it has excellent resistance to corrosion from H2S, CO2 and Cl-, and is the best choice for oil well pipes in sour gas fields.
