Difference between d2 steel and cr12mov

In the field of steel, d2 steel and cr12mov are two widely used high-performance steels, their performance and characteristics are unique, but few people have compared them in depth. This paper will conduct a detailed comparative analysis of these two kinds of steel, explore their performance, characteristics and application scenarios, to help everyone better understand and choose these two kinds of steel.

First, the performance difference between d2 steel and cr12mov

1. Hardness difference

There are obvious differences in hardness between d2 steel and cr12mov. The hardness of d2 steel is generally between 55 and 60HRC, while the hardness of cr12mov is between 58 and 62HRC. Although the hardness difference between the two is not large, in specific applications, this hardness difference may affect the wear resistance and durability of the material.

2. Strength difference

In terms of strength, cr12mov is stronger than d2 steel. The tensile strength of cr12mov is between 900-1100MPa, while the tensile strength of d2 steel is between 700-900MPa. This means that cr12mov may be more suitable for occasions where high strength is required.

2. The characteristics of d2 steel and cr12mov are different

1. Corrosion resistance

d2 steel is superior to cr12mov in corrosion resistance. d2 steel contains 12% chromium, which has good corrosion resistance and can remain rust free in most environments. The chromium content of cr12mov is only 11%, and the corrosion resistance is slightly worse than d2 steel.

2. Wear resistance

In terms of wear resistance, both d2 steel and cr12mov have excellent performance. However, due to the slightly lower hardness of d2 steel, its wear resistance may be slightly worse than cr12mov.

Third, the application difference between d2 steel and cr12mov

1. Tool manufacturing

In the field of tool manufacturing, d2 steel and cr12mov are widely used. However, due to the better wear and corrosion resistance of d2 steel, it may be more suitable for the manufacture of some tools that need to be used in harsh environments. cr12mov, due to its high strength, has advantages when manufacturing large tools.

2. Mold manufacturing

In the field of mold manufacturing, cr12mov is widely used in the manufacture of various types of molds due to its high strength and wear resistance. d2 steel, because of its good corrosion resistance, has an advantage in the manufacture of some molds that need to be used in corrosive environments.

In SUMMARY:

By comparing the depth of d2 steel and cr12mov, we can see that the two steels have their own advantages and are suitable for different scenarios. Which steel to choose needs to be determined according to the needs of the actual application. I hope this article can provide you with some valuable information to help you better understand and choose steel.
