hastelloy G-3/UNS N06985 sheet/bar/pipe

Parameter

Designated as UNS N06985 or DIN 2.4619, Hastelloy G3 (also known as “Alloy G3”) is 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. Hastelloy G3 is generally used for flue gas scrubbers and for handling reducing acids such as phosphoric and sulfuric.
