Hastelloy G3 nickel alloy steel plate is a kind of nickel base high temperature alloy steel plate composed of nickel, chromium, cobalt, tungsten and other elements, what we should take attention is that nickel content is about 37%.
Compared with other nickel base and iron base alloy, Hastelloy G3 nickel alloy steel plate showed better resistance in commercial phosphoric acid. Hastelloy G3 nickel alloy steel plate grows with each passing day being used as acid evaporators in fertilizer industry.
Hastelloy G3 nickel alloy steel plate applications:
phosphoric acid equipment, sulfuric acid, nitric acid equipment, nuclear fuel reprocessing, nuclear waste disposal, pickling, petrochemical products, gold extraction, pesticide production, chemical fertilizer production.
Hastelloy G3 nickel alloy steel plate cold working:
Cold forming may be done using standard tooling although plain carbon tool steels are not recommended for forming as they tend to produce galling. Soft die materials (bronze, zinc alloys, etc.) minimize galling and produce good finishes, but die life is somewhat short. For long production runs the alloy tool steels ( D-2, D-3) and high-speed steels (T-1, M-2, M-10) give good results especially if hard chromium plated to reduce galling. Tooling should be such as to allow for liberal clearances and radii. Heavy duty lubricants should be used to minimize galling in all forming operations. Bending of sheet or plate through 180 degrees is generally limited to a bend radius of 1 T for material up to 1/8" thick and 2 T for material thicker than 1/8". In order to avoid "orange peel" surface effect the cold work reduction of area should be greater than 15% at any given operation. Intermediate annealing may be done, to restore ductility, during the sequence of cold forming operations.
Hastelloy G3 nickel alloy steel plate can prevent the welding heat affected zone of grain boundary precipitates formed welded, so Hastelloy G3 nickel alloy steel plate are suitable for being used in various chemical processing engineering.
When Hastelloy G3 nickel alloy steel plate is forged, the temperature ranges from 2100 F to 1700 F and be sure to anneal after forging to restore corrosion resistance.
