其成分特征是碳含量在共析点左右的高碳低锰钢轨钢。
The main characteristics of the rail steel are low manganese and high carbon which content is being closed to eutectoid.
高于此点,由于超过共析点钢完全由珠光体和退火状态的渗碳体组成,硬度增加并不多。
Above this point the hardness can be increased only slightly, because steels above the eutectoid point are made up entirely of pearlite and cementite in the annealed state.
