A spherically shaped wear part made from a cermet material is provided. The cermet material is a Ti(C, N)-based cermet comprising hard Ti(Cy, Nz) grains, with y > 0, z ≥ 0 and y + z ≤ 1, embedded in a ductile binder phase formed by a Ni-base alloy, a Co-base alloy, or a Fe-base alloy. The Ti(C, N) grains have a mean grain size in the range between 0.2 μrm and 3.0 μrm. |
