| Abstract: | The crystal and carbonization are fined and dislocated martensite become increased after cold-punching die made of GCr15 steel double-fined treatment.At the same time,there are more retained austenite around.Double-fined treament can effectively improve strength and toughness of GCr15 steel;accordingly increase service life of cold-punching die made of GCr15 steel. |

| Keywords: | GCr15 steel cold-punching die double-fined treatment service life of dies |
