镍基高温合金钢【GH90钢板】耐腐蚀性钢板
Summary of GH90 alloy characteristics and application fields. The alloy is aging deformation of reinforced nickel-based superalloy, contains a high amount of cobalt and a variety of reinforcement element, the alloy in 815 ~ 815 ℃ has higher tensile strength and creep resistance, good resistance to oxidation and corrosion resistance, in cold and hot again and again under the action of alternating have high fatigue strength and good formability and weldability. Used for turbine engine turbine disc, blade, high temperature fasteners, clamp, sealing ring and elastic element, etc.
