碳素结构钢

碳素结构钢综合力学性能（强度、延伸率等）及工艺性能（弯曲）良好，尺寸精度高，并且有良好的焊接性能，适用

于简单加工的构件。可用于汽车一些结构件，如车厢边框及中底板和各种加强板。

Carbon structural steel is featured with good comprehensive mechanical performance (strength and enlongation, etc.) 

and process performance (bending), high dimensional accuracy and excellent welding performance. They are suitable to 

manufacturing structural members with simple processing and may be used as some structural parts for automobiles, such 

as car body frames, middle base plates and various reinforcement plates.
