Abstract
An abrasion resistant steel consisting essentially of 0.05 to 0.45 wt. % C, 0.1 to 1 wt. % Si, 0.1 to 2 wt. % Mn, 0.3 to 1.5 wt. % Ti, at most 0.005 wt. % N and the balance Fe as the basic elements contributing to the enhancement of the abrasion resistance property, without excessively increasing the hardness of the steel. In addition to the 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 enhance the quenching hardenability of the steel, and 0.01 to 0.5 wt. % V may be added to enhance the precipitation hardenability of the steel.
