Finished Working Tungsten Carbide Seal Bushing To Close Container
Tightly
Making of tungsten carbide material, tungsten carbide bushing shows high hardness and transverse rupture strength, and it has
superior performance on resisting abrasion and corrosion, which
enable it to be widely used in many industries.
Base on different application of the users, tungsten carbide bushes
are usually made of different tungsten carbide grades. The major
two series of tungsten carbide grade is YG series and YN series.
Generally speaking, YG series tungsten carbide bushes have higher
transverse rupture strength, while YN series tungsten carbide bush
resist corrosion better than the former one.
Grade and Recommended Application:
| Grade | Density (g/cm³) | Hardness (≥HRA) | Strength (Mpa) | Recommended application |
| YG20 | 14.30-14.50 | 86.5 | 2500 | Maximum hardness,excellent wear resistance.Mostly for the last 1-2 stands of good high speed bars. |
| YG25 | 14.10-14.30 | 85.5 | 2520 | Higher wear resistance and moderate impact resistance in the series.Mostly for the last 1-3 stands of good high speed bars. |
| YG30 | 13.90-14.10 | 84 | 2520 | Moderate wear resistance and impact resistance.Good for general purpose.Used in the last 1-4 stands or all stands or finishing mills. |
| YG40 | 13.60-13.80 | 83.5 | 2570 | Best for general purpose.Mostly for the front stands of good mills and in the rear stands of common mills. |
| YG45 | 13.45-13.65 | 82.5 | 2570 | Used in the first and second stands of finishing mill and in the stands of pre-finishing rolling mills . For every milling lines of low speed rolling, low precision and unstable operation. |
| YG55 | 12.90-13.10 | 81 | 2570 | Maximum binder content in YGH series Good toughness and thermal crackresistance. For every milling lines for low speed rolling, low precision and unstable operation. Mostly for the stands of pre-finishing rolling mills and hot rolling of cribbed steel. |
