What type of grinding disc is suitable for grinding relatively hard materials, such as high-strength steels like P91 and P92?
For high-strength steels such as P91 and P92, it is recommended to use diamond grinding wheels for polishing. Diamond grinding wheels have high hardness and wear resistance, making them suitable for grinding and polishing materials with high hardness. At the same time, it is also important to choose the appropriate grain size; different grain sizes should be selected based on specific requirements in order to achieve a better polishing effect. .
