Abstract (en)
An abrasion-resistant steel consists essentially of 0.05 to 0.45 wt. % C, 0.1 to 1 wt. % Si, 0.1 to 2 wt. % Mn, 0.05 to 1.5 wt.% Ti and the balance being Fe and inevitable impurities, the steel includes at least 200 of precipitates of 1.0 mu m or more in particle size per 1 mm<2> and the precipitates contains Ti. In addition to the above basic elements, at least one element selected from the group consisting of 0.1 to 2 wt. % Cu, 0.1 to 10 wt. % Ni, 0.1 to 3 wt.% Cr, 0.1 to 3 wt. % Mo and 0.0003 to 0.01 wt.% B may be added to the steel or at least one element selected from the group consisting of 0.005 to 1 wt.% Nb and 0.01 to 1 wt.% V may also or alternatively be added to the steel. <IMAGE>
