Examples of erosive applications

These Tungsten Carbide parts not only have to resist external erosive wear from high velocity fluids containing solid particles, but they also have to be strong enough to contain pressures of 1,000 bar (14,000 psi) inside the cross-holes. The grade chosen was one with 10% cobalt binder, and a grainsize of under 1 micron. This has an amazing bending strength of 2,750 MPa (400,000 psi) and an apparent hardness of 1,700 HV. The parts were supplied within 4 weeks of ordering.
