Zusammenfassung:A thick NM500 wear-resistant steel, relating to the field of metallurgical technology and comprising the following chemical components by mass percentage: 0.26%-0.30% of C, 0.20%-0.60% of Si, 0.60%-1.00% of Mn, P ≤ 0.012%, S ≤ 0.003%, 0.60%-0.90% of Cr, 0.35%-0.50% of Mo, 0.40%-0.60% of Ni, 0.008%-0.030% of Ti, 0.015%-0.050% of Nb, 0.0008%-0.0025% of B, Ceq≤0.75%, with the balance being Fe and inevitable impurities. The production process of the present wear-resistant steel is short, the cost is low, and the produced steel has excellent mechanical properties, large thickness, high hardness, good toughness, and great welding performance.
