We are professional manufacturer for many years. we can provide a wide range of steel products.
Usually bundling for large diameter,small diameter bars in bulk or as customer's demand.
The hardness after heat treatment is higher than D2/1.2379/Cr12Mo1V1, and can reach 61-63HRC after high-temperature tempering (525 ± 5 ℃); In terms of strength and wear resistance, it exceeds Cr12Mo1V1, and its toughness is higher than D2/1.2379/Cr12Mo1V1; The manufactured molds rarely have cracks and fissures, greatly improving their service life; The residual stress after wire cutting processing is smaller than that of Cr12Mo1V1; The cutting and grinding performance exceeds Cr12Mo1V1.
Suitable for manufacturing precision punching dies and stamping dies for cold forging, deep drawing, and wire rolling for wire cutting processing.
