Hastelloy G3
Description:
Hastelloy G-3 (UNS N06985 / W.Nr. 2.4619) 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. Used for flue-gas scrubbers and for handling phosphoric and sulfuric acids.
Features:
Good corrosion resistance
Well weldable and with good stability against grain border corrosion in welded condition
Applications:
Process equipment for flue gas scrubbers
Sulfate compounds
Mixed acids
