High Wear Resistance Tungsten Carbide Rings With High Corrosion Resistance

Product Description

1, OEM and ODM was accepted
2, Best service and quality
3, High precision tolerance

4, High corrosion resistance & high wear resisting

Advantage of the material tungsten carbide:

Tungsten carbide rollers possess good thermal conduction property.

Compared with other materials ,it is much better in term of heat-resistance,

wear-resistance and strength. Its hardness reduce a litte under the condition of high temperature.

Grade Recommended applications
YGH20 Maximum hardness ,excellent wear resistance in the series.Used in the last 1-2 stands of good high speed line mills for rolling common and hard bars.
YGH25 Higher wear resistance,moderate impact resistance in the series.Used in the last 1-3 stands of good high speed line mills for rolling common and hard bars.
YGH30 Moderate wear resistance and impact resistance,good for general purposes.Used in the last 1-4 stands of finish rolling mills.
YGH40 Best for general purposes.Used in the front stands of good mills and in the rear stands of common mills.
YGH45 Used in the first and second stands of finish rolling mills and in the stands of prefinish rolling mills.For every stand of the rolling lines for low speed rolling,low precision and unstable operation.
YGH55 Maxmum binder content in YGH series,good toughness and crack resistance.Used in the stands of perfinish rolling mills and for rolling screw thead steel
