Abstract (en)
[origin: EP2154262A1] An abrasion resistant steel excellent in bending formability and suitable for members, e.g., power shovels, which come into contact with earth and sand, and a production method thereof are provided. Specifically, the steel contains, on a percent by mass basis, 0.05% to 0.35% of C, 0.05% to 1.0% of Si, 0.1% to 2.0% of Mn, 0.1% to 1.2% of Ti, 0.1% or less of Al, at least one element of 0.1% to 1.0% of Cu, 0.1% to 2.0% of Ni, 0.1% to 1.0% of Cr, 0.05% to 1.0% of Mo, 0.05% to 1.0% of W, and 0.0003% to 0.0030% of B, if necessary at least one element of 0.005% to 1.0% of Nb and 0.005% to 1.0% of V, and the remainder including Fe and incidental impurities, where DI* represented by the following formula is less than 60. DI * = 33.85 × 0.1 × C * 0.5 × 0.7 × Si + 1 × 3.33 × Mn + 1 × 0.35 × Cu + 1 × 0.36 × Ni + 1 × 2.16 × Cr + 1 × 3 × Mo * + 1 × 1.5 × W * + 1 where C* = C - 1/4 × (Ti - 48/14N), Mo* = Mo × (1 - 0.5 × (Ti - 48/14N)), and W* = W × (1 - 0.5 × (Ti - 48/14N)).
