Hastelloy G3/Hastelloy G-3/2.4619/UNS N06985 Nickel Alloy Seamless Pipe
Hastelloy G3/Hastelloy G-3/2.4619/UNS N06985 Nickel Alloy Seamless Pipe
Hastelloy G-3 is a modified version of Hastelloy G in that the higher molybdenum and tungsten contents give this alloy improved corrosion resistance to the welded heat-affected zone. Applications are similar to those for Hastelloy G. Process equipment for flue gas scrubbers, sulfate compounds, mixed acids.
Hastelloy G-3 is a chemically stable and high-temperature resistant alloy, which is well weldable and has a good stability against grain border corrosion in welded condition. Alloy 2.4619 (alloy G-3) is used in flue gas scrubbers, and with phosphoric acid and sulphuric acid.
Huaan International has rich experience of supply Hastelloy series product to customers all over the world. Our product range of Hastelloy G-3 are bar, tube/pipe, plate, fitting, forging, flange and accessories.
