Results of examination and analysis indicated that in normal non high temperature diffused-superfining trea- ted H13(4Cr5MoSiV1)steel products there were massive eutectic carbides with serious banding segregation and transverse impact toughness of steel was lower; and in available high temperature difused and superfning treated H13 steel products
the eutectic carbides were basically dismissed
the banding segregation and structure homogeneity improved obviously and the transverse impact toughness of steel increased appreciably.
