Fourth, the production process.
The production process of NICR15Fe8 nickel-based alloy material mainly includes casting, welding, heat treatment and other links. These process steps play a crucial role in the performance and quality of the material. The specific production process is as follows:
1.Casting process: Casting is one of the important links in the production of NICR15FE8 nickel-based alloy materials. In the casting process, parameters such as melting temperature, pouring temperature and cooling rate should be controlled to ensure the stability of the composition and microstructure of the material. At the same time, in order to improve the mechanical properties and corrosion resistance of the material, some refiners and alloying elements can be added during the casting process.
2.Welding process: Since NICR15Fe8 nickel-based alloy material has good welding properties, it can be welded by various welding methods. In the welding process, it is necessary to select appropriate welding materials and process parameters to ensure the quality of welded joints. At the same time, in order to prevent oxidation or corrosion of the material during the welding process, the material can be pretreated and protected before welding.
3.Heat treatment process: heat treatment is one of the important means to improve the mechanical properties and corrosion resistance of NICR15FE8 nickel-based alloy materials. By controlling process parameters such as heating temperature and holding time, the microstructure and phase composition of the material can be changed, so as to improve the performance of the material. At the same time, in order to prevent oxidation or corrosion of the material during heat treatment, the material can be pretreated and protected before heat treatment.
