Please tell me which is better to make a knife DC53 or M2

Suzhou Chaobo metal materials **** for you to answer.

1. The hardness of DC53 is higher than that of SKD11 after heat treatment, and the high hardness of 62-63HRC after tempering at high temperature (520-530) can be reached, which exceeds SKD11 in terms of strength.

2. The toughness is twice that of SKD11. The toughness of DC53 is more prominent in cold work die steel, therefore, cracks and chipping are rarely seen in DC53, which greatly improves the service life.

3. Wire cutting.

Residual stress after machining.

4. The machinability exceeding the machinability is better than SKD11. As a result, the use of DC53 increases tool life and reduces machining steps. Usage:

Punching dies, cold work forming dies, cold drawing dies, forming rolls, punches, precision blanking for wire cutting and various purposes, stamping dies, plastic deformation tools for difficult-to-process materials.

DC53 is much lower than M2, so it is recommended that you use DC53

The ** of m2 is too high. It's up to you to see what you use this knife for. Specific examples of die steel selection can be described in detail in the search "Selection of Cold Work Die Steel: Huangshi Daye Dongxin Special Steel".

Advantages of DC53 steel knives: good wear resistance, good impact strength, excellent processing performance; Disadvantages: high initial investment, complex initial heat treatment

First, the advantages. 1. Good wear resistance: One of the main advantages of DC53 steel is its wear resistance.

Due to the presence of a variety of alloying elements such as CR and MO, its surface hardness is very high, making it effective in resisting cutting and wear. For some materials with high wear resistance, such as stainless steel, aluminum alloy, plastic, etc., making cutting tools with DC53 steel is very suitable.

2. Good impact strength: DC53 steel not only has high hardness, but also good impact strength. Due to the large number of different low-temperature impact absorbing elements, DC53 steel is able to guarantee excellent impact resistance at high strength.

As a mold for stress concentration parts, it is especially suitable for brewing, die-casting, extrusion and other processing methods.

3. Excellent processing performance: the processability of DC53 steel is also very good. Its heat treatment process has little impact on processing, which can ensure the shape and dimensional stability of the mold, and also ensure the precision and durability of the cutting edge.

Cutting tools made with DC53 steel are not only able to cut high-precision parts, but also better maintain the quality and speed of the cut.

Second, the shortcomings. 1. High initial investment: Relatively refers to some conventional types of tool steel, the first grade of DC53 steel is also relatively high, which has also become the reason why some customers choose traditional steel.

2. The primary heat treatment is more complicated: heat treatment is required to give full play to the performance of DC53 steel, but because of the special nature of the steel material, the primary heat treatment needs to consider many details and is more complicated. Without the right heat treatment process, it will greatly reduce the service life and effect of DC53 steel.

Characteristics of DC53 steel:

1. The hardness of heat treatment is higher than SKD11, and the high hardness of 62-63HRC can be reached after high temperature tempering, and DC53 exceeds SKD11 in terms of strength and wear resistance.

2. The toughness is twice that of SKD11, and the toughness of DC53 is more prominent in cold work die steel, and the tools made of DC53 rarely appear cracks and cracks, which greatly improves the service life.

3. The residual stress after wire cutting processing is small, and the residual stress is reduced by high temperature tempering, and the cracks and deformation after wire cutting processing are suppressed.

4. The machinability and abrasiveness exceed SKD11, and the abrasiveness of DC53 is better than that of SKD11, and the use of DC53 can increase the life of tools and molds and reduce the processing process.
