一种具备高硬度超高耐磨性钢板及其生产方法
摘要：
本发明公开了一种具备高硬度超高耐磨性钢板及其生产方法，所述钢板化学成分组成及其质量百分含量为：C：0.33～0.35%，Si：0.25～0.40%，Mn：0.50～0.60%，P≤0.010%，S≤0.003%，Cr：1.10～1.20%，Mo：0.30～0.35%，Ni：0.30～0.35%，Al：0.020～0.040%，Nb：0.020～0.040%，余量为Fe和不可避免的杂质；所述生产方法包括冶炼、连铸、加热、轧制、轧后冷却和热处理工序。本发明钢板具有纯净度较高、成分均匀、内部致密的特点，力学性能优良，完全适用于在超强磨损恶劣工况下服役的高耐磨性结构件的制造。
摘要（英）：

The invention discloses a high-hardness ultra-high wear resistance steel plate and a production method thereof. The chemical composition of the steel plate comprises, by mass percentage, 0.33-0.35% ofC, 0.25-0.40% of Si, 0.50-0.60% of Mn, no more than 0.010% of P, no more than 0.003% of S, 1.10-1.20% of Cr, 0.30-0.35% of Mo, 0.30-0.35% of Ni, 0.020-0.040% of Al, 0.020-0.040% of Nb, and the balance Fe and unavoidable impurities. The production method includes smelting, continuous casting, heating, rolling, post-rolling cooling and heat treatment processes. The steel plate has the characteristics of being high in purity, uniform in composition and dense in interior, has excellent mechanical properties, and is fully suitable for the manufacture of high wear resistance structural parts serving under super wear and bad conditions.
