Advantages of our valve seat
1. High temperature resistance
The strength keeps stable up to 800 and it can even momentarily used at 1200.
2. Wear resistance
Due mainly to the unique inherent characteristics of the hard carbide phase dispersed in a
CoCr alloy matrix, it has exceptional wear and galling resistance.
3. Corrosion resistance
This exellent and lovely property allows this kind of material parts to be used in oil&gas, slurry, acid
liquid and any other mediums.
4. Production process
Powder metallurgy pocess, it has better strength than casting parts, better granule structure and
avoiding the troubles caused by casting defects.
Founded in 2001, Shenyang Top New Materials Co., Ltd. has concentrated to research, development and production of cobalt-base alloys, tungsten-base alloys, nickel-base alloys and metal ceramics for 15 years.
Our products like cobalt-base alloy saw tips, valve balls, valve seats, bushings, rods, chemical fiber blades, hot-extrusion dies, thermocouple protective tubes have been well recognized by over 30 countries and established long term cooperation.
