摘要
对30Mn2钢进行不同方式热处理、拉伸试样及矿用连接环静拉伸试验表明,只要热处理工艺合适,30Mn2钢可替代20MnVB钢制造矿用连接环.
This peper deals with the study on several kinds of neat treatment of 30Mn2 steel. The result of the static tensile test on sample and the link ring shows that.as long as the heat -treatment technolgy is suitable,we can substitute 30Mn2 steel for 20MnVB steel to make the link ring.
