使用状态的组织为细晶粒的铁素体—珠光体，强度比普通碳素结构钢Q235高约20%～30%，耐大气腐蚀性能高20%～38%。
Using the state of the organization for the fine grain ferrite pearlite, strength than ordinary carbon structural steel Q235 about 20% ~ 30%, high atmospheric corrosion resistance of 20% ~ 38%.
作为结果的组织结构是初步的共析铁素体(在共析反应前的铁素体)和部分珠光体的混合物。
The resulting structure is a mixture of primary or pro-eutectoid ferrite (ferrite that formed above the eutectoid reaction) and regions of pearlite.
应用电子衍衬技术和扫描电镜等手段，对共析珠光体轨钢的微观结构和断裂过程，进行了观察和分析。
The microstructure and fracture process of an eutectoid pearlitic steel have been observation and analysed by means of electron-diffraction-contrast technique and SEM.
