A8 cold work steel is similar to A2,S7.
The toughness is twice as high as SKD11 cold working steel, making complex dies, and the tensile die has large anti-cracking and collapsing properties. The mold is tempered at 520-530℃, and the hardness is still 61-63HRC, which reduces the cracking accident caused by residual stress of the wire-cutting mold.
3. Suitable for surface hardening treatment, so that the mold life is longer.
