低合金折磨铸钢因具有较好的机械性能、抗磨性能、较高的摔透性及具有与碳钢相近的铸造性能引起人们的普遍关注。用它制造承受小冲击力的抗磨件代替高锰钢件已取得了显著的经济效益，但用它制造承受冲击力较大的折磨件则尚嫌韧性不足，因此，提高多元低合金抗磨铸钢韧性，扩大 Low alloy torpedo cast steel has attracted people’s attention because of its good mechanical properties, anti-wear properties, high penetrating and casting properties similar to carbon steel. Made with it to withstand the impact of small wear-resistant parts instead of high-manganese steel parts has made significant economic benefits, but the use of it to bear the greater impact of the torture pieces are not too tough enough, therefore, to improve multi-element low alloy anti-wear Steel toughness, expand
