Introduction to GH2706 (GH706) high temperature alloy materials
GH706 high temperature alloy plate, GH2706 high temperature alloy rod, seamless pipe, etc. can be customized
GH2706 high temperature alloy is a Fe-Ni-Cr based precipitation hardening deformed high temperature alloy with a service temperature below 550℃-650℃. This alloy is a modified alloy of GH4169 alloy and its properties are similar to GH4169 alloy. Due to the reduction of niobium content in the alloy, it has better production process performance, hot and cold processing performance and welding performance. The alloy has high strength, good oxidation resistance and corrosion resistance below 700°C. This alloy can produce large and super-large high-temperature alloy products, and is suitable for making parts such as aero-engine casings, diffuser casings, turbine disks, and fasteners. It can also be used to make large-diameter rings suitable for gas turbines for cycle power generation. pieces. The main products include bars, forgings, rings, sheets and strips, etc.

GH2706 high-temperature alloy has been used to manufacture parts such as engines, high-pressure compressors, and extended casings.
The alloy has a wide hot working temperature range and has high plasticity in the range of 850℃-1150℃. When the deformation rate is 0.01, it quickly enters the steady-state rheology stage at 900℃-1100℃, and then the true stress changes very little, which is extremely beneficial for blanking and hot processing of large shapes. In the three-stage heat treatment of the alloy, 843°C*3h is the stabilization treatment. After the treatment, there is a large amount of eta phase on the grain boundaries. The existence of eta phase is conducive to the improvement of durable performance.
