Tungsten Carbide Seal Rings advantage

1) It is not like silver will get black, not like copper jewelry allergy prone,not like alloy jewelry because of lead.

2) It is heavier than most metals because of its density.

3) The hardest form of tungsten carbide is harder than titanium alloys.

4) Tungsten carbide jewelry does not tarnish and oxidize, You can't beat its shine and polish.

5) It's Cobalt Free and Hypoallergenic, so if you have any allergies, it won't happen with tungsten.

6) Tungsten rings will never bend and never scratch. File away at it, and it will stay polished forever.

7) Tungsten rings are very hard, affordable, last longer, do not fade, and come in more shapes and styles.

8) Tungsten Jewelry are imperceptible in difference to more expensive rings yet require less care and cost less money.

Tungsten Carbide Seal Rings Advantage

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
