Abstract：

For N06625 nickel-based alloy plate industrially produced by Taiyuan Iron and Steel Group Co., Ltd., its microstructure and properties were studied by metallographic microscope, scanning electron microscope, energy spectrum analysis and other methods. The results show that in the industrial production of N06625 nickel-based alloy plate, the rolled precipitates are mainly strip-shaped (Nb, Ti) (C, N) and fine MoNbC composite precipitates. The suitable heat treatment temperature of high-strength grade N06625 nickel-based alloy plate is about 1000 ℃, while that of low-strength grade plate is about 1150 ℃. The produced N06625 nickel-based alloy plate has excellent metallurgical purity, mechanical properties and corrosion resistance, providing data support for user to select materials.
