Inconel706

Inconel 706 is an Fe-Ni-based high-temperature alloy with γ' phase, γ'' phase, η phase and MC-type carbides as the main second phases. Because of its excellent castability, easy processing and reliable high temperature mechanical properties, Inconel 706 alloy is suitable for the preparation of oversized disk forgings with a diameter of 2000 mm or more. At present, the international mainstream "E" class, "F" class heavy-duty combustion engine turbine disc material mostly choose Inconel 706 alloy manufacturing.

Inconel 706 is used at 500 ℃, a very widely used Fe-Ni-based high-temperature alloy, with small segregation, superior processing performance, low cost and other characteristics, widely used in turbine engines, gas turbines and nuclear industry, has a very high economic significance. Inconel 706 features: Inconel 706 is Fe-Ni-Cr-based precipitation-hardening deformation high-temperature alloy, the use of temperature below 550 ℃ - 650 ℃, the alloy is a modified alloy of GH4169 alloy, its characteristics are similar to GH4169 alloy. Inconel 706 alloy has high strength, good oxidation resistance and ability below 700℃. It can also be used to make large diameter ring parts suitable for gas turbines for circulating power generation. Inconel 706 alloy has a wide range of hot working temperature, in the range of 850 ℃ - 1150 ℃ with high plasticity. At a deformation rate of 0.01, it quickly enters the steady-state rheological stage at 900°C-1100°C. Subsequent changes in true stress are minimal, which is extremely beneficial for large definite open billets and thermal processing. The alloy is stabilized at 843°C*3h in three heat treatments, and after the treatment, a large amount of η phase exists at the grain boundaries, and the presence of η phase is beneficial to the improvement of the persistent properties.
