China TC seal ring high quality with best price 

1. Tungsten carbide sealing ring has the advantages of wear resistance, corrosion resistance characteristics, widely used in petroleum, chemical and other fields of mechanical seal, the product has a flat ring (PH) and step type ring (th) and other special-shaped ring, the specifications from Ø 12mm to 400mm;

2 product after nice grinding, size and tolerance of minimal sealing performance is more superior

3 process in the process of adding corrosion resistant rare elements, sealing performance is more durable;

4 high strength and hardness of hard alloy material, no deformation, more compression.

Technical requirements for sealing rings

1 The bank tungsten carbide grades and their physical, mechanical properties and metallographic should meet the requirements of the relevant standards:

2 blank off the edge, the depth of the drop is not more than 0.33mm;

3 the surface of the blank must not be peeling, bubbling, delamination, crack, porosity, over burning, less burning and so on;

4. The blank section of the organization should be uniform, not a black, air bubble, delamination, crack, serious carburization and decarburization and not press good defects.


Inspection rules and methods:

Blank inspection rules and the implementation of GB5242


Introduction of tungsten carbide ring

Tungsten carbide  rings are made of the hardest metal on earth, they are tougher and more durable than the titanium rings. This is commonly used as a seal ring, disc cone, instrument etc.. tungsten ring, tungsten carbide ring between the difference maker does not include tungsten carbide of tungsten ring, tungsten ring only basically is a steel ring. It's hard, but it doesn't scratch. Tungsten carbide rings can only be scratched by diamond or corundum products containing minerals.



Tungsten carbide ring is the most wearable ring on earth.

Tungsten is about 10times harder than gold,5times harder han tool steel,4times harder than titanium.

Due to its extremely high hardness,tungsten carbide rings can be kept for long periods of time in the ring than any other ring in the market

Tungsten carbide ring,known as the “permanet aperture”

Tungsten carbide ring will not bend

Grade information:

Recommend to YS2T (92HRA)

                           YG8 (89HRA)




With high hardness, wear resistance, strength and toughness, good heat resistance, corrosion resistance and other a series of excellent properties, especially its high hardness and wear resistance, even at a temperature of 500 DEG C also remained unchanged, at 1000 DEG C still very high hardness.
