中型电机轴用45~#钢机械性能的试验研究

Test for the Mechanical Property of 45~# Steel for the Shaft of the Medium-Sized Motor

通过试验得出 4 5 # 优质碳素钢在未热处理条件下 ,其机械性能不能满足普通中型电机轴的设计要求 。

It is concluded from the test that the mechanical property of the high quality 45 # carbon steel can't meet the requirements of the shaft design of the conventional medium sized motor if heat treatment of it is not carried out,and the steel can be used after heat treatment.
