Customized High Precision Cemented Carbide Valve Seat For
Petrochemical Industry
Application
Tungsten carbide also called tungsten cemented carbide, cemented
carbide or simply carbide.Tungsten carbide (WC) is an inorganic
chemical compound containing equal parts of tungsten and carbon
atoms. Tungsten cemented carbide can be pressed and formed into
shapes from fine
gray powder, which is considered to be its most basic form.Tungsten
cemented carbide plate is approximately three times stiffer than
steel, with a Young's modulus of approximately 550 GPa, and is much
denser than steel or titanium. It is comparable with corundum or
sapphire in hardness and can only be polished and finished with
abrasives of superior hardness such as cubic boron nitride and
diamond among others, in the form of powder, wheels, and compounds.
Tungsten cemented carbide is the preferred material for parts that
must withstand all forms of wear (including sliding abrasion,
erosion, corrosion/wear and metal-to-metal galling) and exhibit a
high degree of toughness. It exhibits high compressive strength,
resists deflection, and retains its hardness values at high
temperatures, a physical property especially useful in
metal-cutting applications.
