dc53

DC-53 is a general purpose, cold work die and mold steel that also provides excellent strength and toughness that approaches those of high-speed steels. DC53, is an improvement over alloy tool steel D-2. It eliminates the disadvantages of insufficient hardness and toughness that are a result of high-temperature tempering found with D-2. DC-53 is typically chosen as a replacement for D-2 in use for general purpose and precision dies. DC-53 is noted for causing less tool wear and machining times that are faster than D2 Tool Steel.

In the case of proper heat treatment, the strength and toughness are excellent, and the high temperature tempering hardness can reach 62~63HRC.

The toughness of DC53 is more prominent in cold work die steel, and the tools made of DC53 rarely show cracks and cracks, which greatly improves the service life.

The residual stress after wire cutting is tempered at high temperature to reduce the residual stress. Therefore, cracks and deformation after online cutting of large molds and molds that require precision are suppressed.
