AISI D2 D3 D5 D6 Hot Forged Rolled Tool Steel Flat Bar for tools and dies
D2 steel round bar and plate can be used to produce cold work mold with a large cross-section, complex shape, high impact force, and high wear resistance. It has high hardenability and the high-temperature oxidation resistance is good. The anti-corrosion ability is good after quenching and polishing, and the deformation is small after the steel heat treatment. D2 tool steel composition and more information as below.

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.
