Abstract: | This article introduces the fragmentation of 34CrMo4 hot wiled seamless steel tubes when straightening,and takes sample analysis of it. It is got that the cause is abnormal bainite structure, and constructive suggestion for avoiding abnormal bainite strueture when producing 34CrMo4 hot rolled seamless steel tubes is proposed. |
