Hastelloy G-3/UNS N06985 Sheet/Bar/Pipe
Hastelloy® G-3 is a grade of Hastelloy® which is a nickel-molybdenum alloy. There are many different grades of Hastelloy®, which includes G-3. Grades of Hastelloy® have each been optimized for a specific purpose. Molybdenum makes Hastelloy® harder and stronger at high temperatures. This alloying element and the characteristics it imbues into the material also makes it great for welding applications. These nickel alloys are easily fabricated and formed. They also exhibit good ductility and are able to be cold worked.
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.
