ABSTRACT:
There is now provided a roll for hot rolling comprising 70-95 weight %, preferably 85-94 weight %, WC in a binder phase consisting of only cobalt or alternatively a Co--Ni--Cr alloy containing 20-35 weight % Ni and up to 10 weight % Cr, possibly with small additions of molybdenum. The WC grains are rounded with an average grain size between 3-10 .mu.m, preferably 4-8 .mu.m. The maximum grain size should not exceed 2 times the average grain size and no more than 2% of the grains be less than half of the average grain size.
