Due to the few alloy addition and its low cost, this low-alloy wear-resistant steel has obvious economic and social benefit.

这种低合金耐磨钢的合金加入量较少，成本低廉，具有明显的经济与社会效益。

Therefore the amount of carbon and alloy addition should be decreased during LF refining to decrease the raise of nitrogen in steel.

因此在LF精炼时减小碳和合金加入量可减少钢中氮含量的增加。
