1. Low alloy

In order to meet the performance of the die, the high-carbon and low-alloy die lamp is smelted by adding an appropriate amount of alloy elements such as chromium, nickel, manganese, molybdenum, titanium, tungsten, vanadium and silicon on the basis of carbon tool steel. The addition of alloy elements improves the moldability of cold working die steel, and the addition of alloy elements improves the hardenability of cold working die steel, The tendency of easy deformation and cracking of the die is reduced. Therefore, this popular cold work die steel is mainly characterized by low fire contact temperature, good power, small heat treatment deformation and strong toughness.

2. Medium alloy

Due to the relatively low carbon content and low chromium content, it belongs to hypereutectoid steel. There are a lot of eutectic carbides in the structure, a lot of residual austenite after quenching, small deformation, high wear resistance and large bearing capacity after heat treatment. The carbides in this kind of cold working die steel are mainly Cr7C3 type and a small amount of M6C and MC type. It has the characteristics of good wear resistance and small heat treatment deformation.

3. High alloy

High alloy cold working die steel has higher hardness, compression resistance and wear resistance, can meet various service needs, and has a longer service life. This type of cold working die steel is a commonly used type. After heat treatment, it has small deformation, high wear resistance and large bearing capacity. Therefore, it can be widely used in large and medium-sized cold working dies.

To sum up, the classification of cold working die steel mainly includes low alloy, medium alloy and high alloy. Because these three different cold working die steels contain different components, their performance also has certain differences.

Cold work die steel is a metal material widely used in industrial production and is mainly used to manufacture various metal molds. This kind of steel has the characteristics of high hardness, high wear resistance, high tensile strength, etc., so it is very popular in the mold industry. There are many types of cold work die steel on the market, and different types of steel are suitable for different occasions and production needs.
1.Cr12MoV
Cr12MoV steel is a high-quality cold-work mold steel. Due to its strong wear resistance and high hardness, it is widely used in manufacturing various cold work molds. In addition, Cr12MoV steel also has strong corrosion resistance and can maintain excellent performance in harsh working environments. Therefore, this steel is widely used in aviation, automotive, and other industries.
2. D2
D2 steel is a high-quality cold work die steel with excellent wear resistance and high hardness, as well as good corrosion resistance. This kind of steel is suitable for manufacturing various molds, such as molds, mold seats, mold plates, etc. In addition, due to its high hardness and strength, D2 steel is also widely used in manufacturing knives and cutting tools.
3.Cr12
Cr12 steel is also a common cold work die steel with high hardness and wear resistance and is suitable for manufacturing molds, mold seats, and other parts. In addition, due to its good heat resistance, Cr12 steel is also widely used in mold manufacturing in high-temperature environments.
In short, cold work die steel has high hardness, wear resistance, corrosion resistance, and high-temperature resistance, so it is widely used in industrial production. When selecting cold work die steel, it is necessary to comprehensively consider factors such as production needs and working environment to select a suitable model.
