HSSD DC53 High strength high wear resistance cold working tool steel (improved by D2/1.2379/ASSAB 88/DC53/SKD11)
Introduction
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, ASSAB 88, SLD-MAGIC, AISI D2, W.-Nr.1.2379
Application
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.
Characteristic
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.
Characteristic curve of quenching and temper
Chemical composition
Recommend heat treatment
Technical service
Die vacuum heat treatment and die surface treatment(N-O, C-N, carburize and nitridation surface treatment)
