PROBLEM TO BE SOLVED: To provide an improved wear-resisting steel having an inexpensive component composition. SOLUTION: The steel having≥400 pieces/mm<SP>2</SP>dispersion-density of hardened secondary-phase particles on the basic phase composed of pearlite phase, has the steel composition composed of, by mass, 0.80-1.50% C, 0.05-1.0% Si, 0.1-2.0% Mn,≤0.1% Al, and one or more of 0.1-1.2% Ti, 0.005-1.0% Nb and 0.005-1.0% V and further, one or more of 0.1-1.0% Cu, 0.1-2.0% Ni, 0.1-1.0% Cr, 0.05-1.0% Mo, 0.05-1.0% W and 0.0003-0.0030% B, and the balance Fe with inevitable impurities.
