Because everyone is engaged in different industries and is familiar with the things in his field, the stamping die is still relatively familiar to the people engaged in this industry. If you want to make a good stamping die, what kind of material do you generally choose? Let's take a look with Xiaobian.

1. Low alloy tool steel

Low alloy tool steel is based on carbon tool steel with an appropriate amount of alloy elements. Compared with carbon tool steel, the cracking tendency and quenching deformation are reduced, the hardenability and wear resistance of the steel are improved. Low alloy steels used for manufacturing molds include CrWMn, 9mn2v, 7CrSiMnMoV (code CH-1), 6crnisimnmov (code GD), etc.

2. Carbon tool steel

The carbon tool steels widely used in molds are T8A and T10A, which have the advantages of good processability and low price. However, the hardenability and red hardness are poor, the heat treatment deformation is large, and the bearing capacity is low.

3. High speed steel

High speed steel has the highest hardness, wear resistance and compressive strength in die steel, and its bearing capacity is very high. W18Cr4V (code 8-4-1), W6Mo5Cr4V2 (code 6-5-4-2, American brand m2) with less tungsten and 6w6mo5cr4v (code 6w6 or low carbon m2), a carbon and vanadium reduction high-speed steel developed to improve toughness, are commonly used in molds. High speed steel also needs to be forged to improve its carbide distribution.

4. High carbon medium chromium tool steel

High carbon medium chromium tool steels used for molds include Cr4W2MoV, cr6wv, Cr5MoV, etc. they have low chromium content, few eutectic carbides, uniform carbide distribution, small heat treatment deformation, good hardenability and dimensional stability. Compared with high carbon and high chromium steel with relatively serious carbide segregation, the properties are improved.

The above are some materials for making stamping dies. At present, most of the materials for manufacturing stamping dies are steel. The types of commonly used die working parts include: carbon tool steel, low alloy tool steel, high carbon and high chromium or medium chromium tool steel, medium carbon alloy steel, high speed steel, matrix steel, cemented carbide, steel bonded carbide, etc.
