Other common names: Alloy G3, UNS N06985, W.Nr.2.4619
Hastelloy G3 is a chilled nickel-based alloy with superior performance. The high nickel and molybdenum content extends the acidic use limit of the alloy, while also providing excellent chloride and dissolved oxygen resistance. When the temperature is as high as 400°F, It has strong corrosion resistance in strong acid environments such as high chloride. It is added with molybdenum and copper, so it can resist corrosion in reducing media. The low carbon content helps prevent the sensitization of the welding heat-affected zone and the subsequent intergranular corrosion. Hastelloy G3 has high strength, hardenability, good toughness, small deformation during quenching, high creep strength and lasting strength at high temperatures, and good weldability and intergranular corrosion resistance in the welded state.
1. Strong corrosion resistance to oxides and atmosphere
2. Good ductility when exposed to intermediate temperature for an instant
3. Strong resistance to pitting, crevice corrosion and stress corrosion
4. Excellent knife line and heat-affected zone erosion resistance
