D2 SKD11 1.2379 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.
