The invention concerns an article of a steel which is characterized in
that it consists of an alloy which contains in weight-%: 1.2-2.0 C,
0.1-1.5 Si, 0.1-2.0 Mn, max. 0.2 N, max. 0.25 S, 4-8 Cr, 0.5-3.5
(Mo+W/2), 5-8 V, max. 1.0 Nb, balance essentially only iron and
unavoidable impurities, and that the steel has a micro-structure
obtainable by a manufacturing of the steel which comprises spray forming
of an ingot, the micro-structure of which contains 8-15 vol-% carbides of
essentially only MC-type where M substantially consists of vanadium, of
which carbides at least 80 vol-% have a substantially rounded shape and a
size in the longest extension of the carbides amounting to 1-20 .mu.m.
