Designated as UNS N06985 or DIN 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. 2.4619 is generally used for flue gas scrubbers and for handling reducing acids such as phosphoric and sulfuric.
