Tungsten-cobalt Alloy Sealing Ring PM Sintered Parts
Tungsten-cobalt alloy sealing ring PM sintered parts have a series of excellent properties such as high hardness, wear resistance, good strength and toughness, heat resistance, and corrosion resistance, especially its high hardness and wear resistance, even at a temperature of 500 ° C It also remains basically unchanged at low temperature, and it still has a high hardness at 1000 °C.

Product Advantages
1. Tungsten-cobalt alloy sealing ring PM sintered parts use coarse-grained hard alloy raw materials, and the alloy is sintered under pressure to greatly improve the hardness and toughness of the drill bit at the same time.
2. The unique design greatly improves the service life.
3. There is no need for mold costs, saving costs.
Carbide sealing ring characteristics
1. Tungsten carbide sealing rings have the characteristics of wear resistance and corrosion resistance and are widely used in mechanical seals in petroleum, chemical, and other fields. The products include flat rings (PH), table rings (TH), and other special-shaped rings, and the specifications are Ø12mm- 300mm; 2. The product has been finely ground, the size and tolerance are small, and the sealing performance is excellent;
3. The corrosion-resistant rare elements are added to the process formula, and the sealing performance is more durable;
4. It is made of high-strength and high-hardness cemented carbide material, which is not deformed and more compressive.
Technical requirements for sealing rings
1. The grade of cemented carbide used in the blank and its physical, mechanical properties and metallurgy conform to the relevant standards and standards:
2. The depth of edge drop and corner drop of the blank is not more than 0.33mm;
3. The surface of the blank must not have defects such as peeling, bubbling, delamination, cracks, pores, over-burning, and under-burning;
4. The cross-sectional structure of the blank should be uniform, and there should be no defects such as black hearts, bubbles, delamination, cracks, severe carburization, decarburization, and unpressed.
Product Performance
Tungsten-cobalt alloy sealing ring PM sintered parts have a series of excellent properties such as high hardness, wear resistance, good strength and toughness, heat resistance, and corrosion resistance, especially its high hardness and wear resistance, even at a temperature of 500 ° C It also remains basically unchanged at low temperature, and it still has a high hardness at 1000 °C.
