一种高强度耐磨钢板及其生产方法
摘要：
本发明属于炼钢技术领域，具体涉及一种高强度耐磨钢板及其生产方法，所述高强度耐磨钢板化学成分及重量百分比为：C：0.09‑0.11%、Si：0.68‑0.74%、Mn：1.06‑1.13%、P≤0.016%、S≤0.005%、Als：0.022‑0.038%、Cr：0.50‑0.55%、Mo：0.85‑0.95%、W：0.35‑0.44%、Nb：0.06‑0.07%、Ni：0.67‑0.77%、Ca：0.003‑0.004%，余量为Fe和不可避免的杂质。本发明高强度耐磨钢板硬度高，低温冲击韧性好，综合性能优异，尤其适合寒冷天气条件下使用。
摘要（英）：

The invention belongs to the technical field of steelmaking, in particular to a high-strength abrasion-resistant steel plate and a production method thereof. The high-strength abrasion-resistant steel plate comprises the following chemical components in percentage by weight: 0.09-0.11% of C, 0.68-0.74% of Si, 1.06-1.13% of Mn, less than or equal to 0.016% of P, less than or equal to 0.005% of S, 0.022-0.038% of Al, 0.50-0.55% of Cr, 0.85-0.95% of Mo, 0.35-0.44% of W, 0.06-0.07% of Nb, 0.67-0.77% of Ni, 0.003-0.004% of Ca and the balance of Fe and inevitable impurities. The high-strength abrasion-resistant steel plate is high in hardness, good in low-temperature impact toughness and excellent in comprehensive performance, and is especially suitable for use at cold weather conditions.
