*Brief

A nickel-chromium-iron alloy with additions of molybdenum and copper. It has good weldability and resistance to intergranular corrosion in the welded condition. The low carbon content helps prevent sensitization and consequent intergranular corrosion of weld heat-affected zones. Used for flue-gas scrubbers and for handling phosphoric and sulfuric acids.

*Feature

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. Our product range in 2.4619 (alloy G-3) are tubes and pipes, fittings and flanges, accessories.

*Application

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.
