carbon steel (【技】通常含碳量小于1.35%的铁碳合金，其中还含有限量的硅、锰、磷、硫等杂质及其他微量残余元素。它是近代工业中使用最早、用量最大的基本材料之一。: ① The relation between the intensity of stirring and the ratio of the equiaxed crystal zone in carbon steel is shown in Figure 12. In the upside of a billet, the equiaxed crystal zone increases monotonically with the increase of M-stirring intensity. 碳素钢搅拌强度与等轴晶区比之间的关系示于图12。在小方坯上部，等轴晶区随着结晶器搅拌强度的增加呈单调递增 ° ②Carbon steels are those steels which only contain iron and carbon, and small amounts of other alloying elements. They are the most common and least expensive tool steels. 碳钢是那些仅含有铁和碳以及少量其他合金元素的钢，是最普通、最廉价的工具钢。) |
