摘要
Beiman Special Steel Share Limited Company and Chan gchun No.1 Automobile Manufacturing Factory took samples on the adjacent parts of 5 batches of 40CrH steel bars and carried out the hardenability test. The results indicated that the experimental results of the adjacent samples almo st agreed with each other. It can be thought that the difference between the primary experimental results made by the two units is caused by the segregation of chemical compositions (C, Mn and Cr).
