【Abstract】 The performances of six kinds of heavy-section-hot-die work steels were analyzed according to the material selection of buffer forgings precision die,which shows that the material selection of die steel should be based on the high temperature strength,high temperature impact strength and thermo-stability of heavy-section-hot-die work steels in order to confirm an excellent service performance and longevity of heavy hot-forging die thinking of the familiar failure form.In view of the above,B2(4Cr2MoVNi)steel was selected as a buffer-forgings-die steel.It was proved by industrial production that B2 steel is suitable for making buffer forgings die.更多还原
