1. Corrosion resistance: N08020 shows good corrosion resistance in a variety of acidic, alkaline and saline environments, especially in oxidation-reduction media with excellent corrosion resistance. This is mainly due to its high content of chromium, which can form a dense oxide film and effectively resist various corrosive media.
2. High temperature strength: N08020 can still maintain high strength and hardness at high temperatures, thanks to its good thermal stability. In high temperature environment, N08020 has excellent creep resistance and can withstand high temperature and pressure, so it is widely used in high temperature and high pressure environment.
3. Processing performance: N08020 has good machinability and can be processed by conventional welding, machining, heat treatment and other processes. At the same time, N08020 has excellent welding performance and can be connected by various welding processes, such as argon tungsten arc welding, plasma arc welding, etc.
4. Environmental safety: N08020 does not contain lead, mercury, cadmium and other harmful elements, harmless to the environment and human health. Therefore, equipment and components manufactured with N08020 materials do not pose a hazard to the environment during production and disposal.
