Abstract  By means of the modification of multiple compound agent,eutectic structure of cast Cr12 die steel is refined and the amount of divorced eutectic is increased.After heat treatment,network eutectic carbides of cast Cr12 die steel are changed into granular and dispersed ones.The impact toughness is greatly increased.It ensures the application of cast Cr12 die steel.
Key words:  Cr12 steel      cast die      modification      eutectic carbide granulation
