Product Description
HSSD DC53 High strength high wear resistance cold working tool steel (improved by D2/1.2379/DC53/SKD11)

D53 modified form D2/1.2379/SKD11 etc, with high wear-resisting cold working die steel, HSSD DC53 steel has the properties of high strength and high wear resistant, replace a new generation imported common cold working die steel with high obdurability high wear-resisting,
Key words:
DC53, 1.2990, GS-821, SLD-MAGIC, AISI D2, W.-Nr.1.2379

Precision stamping die;Cold forging;Deep drawing and rub line die;Auto parts bending die;Bicycle parts die;Hydraulic pressure molding die;High speed cutting the punch;Stainless steel plate punch.

1, the high obdurability is higher than that of 1.2379, and the wear- resisting property is good.
2, the high obdurability is more than two times than 1.2379, overcome the weakness of traditional with easy tip or craze, high-temperature resistance tempering stability better than that of 1.2379/D2,in general and precision mold domain can replace 1.2379/D2, its use performance is the same type cold die imported.
