6 different levels of valve corrosion rate
2022-12-20 16:53
1. Full corrosion resistance: the corrosion rate is less than 0.001 mm/year;
2. Extreme corrosion resistance: erosion rate 0.001 to 0.01 mm/year;
3. Corrosion resistance: erosion rate 0.01 to 0.1 mm/year;
4. Corrosion resistance: erosion rate 0.1 to 1.0 mm/year;
5. Poor corrosion resistance: erosion rate 1.0 to 10 mm/year;
6. Non corrosion resistance: the corrosion rate is greater than 10mm/year. Because the corrosion phenomenon generally arises from the spontaneous interaction between metal and the surrounding environment, how to isolate metal from the surrounding environment or use more non-metallic synthetic materials is the focus of corrosion prevention.
