GH4090 (GH90) nickel-based superalloy overview

GH90 is an age-strengthened nickel-based deformed superalloy that contains a relatively high amount of cobalt and various strengthening elements. The alloy has high tensile strength and creep resistance, good oxidation resistance and corrosion resistance at 815 ～ 870 ° C, high fatigue strength and good formability and welding under repeated alternating heat and cold Sex. Mainly supply hot rolled and cold drawn bars, cold rolled sheets, strips and cold drawn materials.

GH4090 (GH90) nickel-based superalloy variety specifications and supply status

Supply cold-drawn rods or cold-drawn hexagonal rods with a diameter or inscribed circle diameter not greater than 25mm; cold-rolled sheet not thicker than 4mm and cold-rolled strip not thicker than 0.8mm; cold springs with a diameter not greater than 8mm Brushed wood. The supply status of cold drawn rods is divided according to the use: the upset rods are delivered in the cold drawn and polished state (when the demand side needs to be delivered in the solid solution state, it should be indicated in the contract); the rods for machining Delivery after solid solution and descaling. The cold-rolled sheet and strip (soft state) are delivered after softening, alkaline pickling and trimming; the cold-rolled sheet and strip (hard state) are delivered after cold rolling and trimming. The wire materials for springs are delivered in cold-drawn or solution-treated state after cold drawing.
