ASTM A128 Mn13 X120Mn12 Wear Resistant Manganese Steel Plate

ASTM A128 Mn13 X120Mn12 Wear Resistant Manganese steel plate

Factors affecting MN13 heat treatment process

1. Heating temperature: Heating temperature is one of the important factors affecting the effect of MN13 heat treatment. The appropriate heating temperature can make the material achieve the ideal organizational structure

High hardness and wear resistance. If the temperature is too high or too low, it may cause the performance of the material to decline.

2. Holding time: Holding time refers to the time when the material is kept at a certain temperature after heating. Holding time too long will lead to coarse crystallization of the material, affecting the performance; Keep warm

If the time is too short, it is difficult to achieve the ideal organization structure. Therefore, choosing the appropriate holding time is crucial to the heat treatment effect of MN13.

3. Cooling media: Different cooling media will affect the performance of the material. Rapid cooling can improve the hardness of the material, but may lead to increased brittleness of the material;

Slow cooling can improve the toughness of the material, but the hardness and wear resistance will be reduced. Therefore, when selecting the cooling medium, it is necessary to make a reasonable choice according to the specific requirements.

4. Cooling speed: Cooling speed refers to the time from heating to cooling of the material. Rapid cooling can make the structure of the material more dense, improve the hardness and wear resistance;

Slow cooling can make the structure of the material more stable and improve toughness. Selecting the appropriate cooling speed according to the specific application requirements is to ensure the effect of MN13 heat treatment

The key.

5. Material size and shape: the size and shape of the material will also have an impact on the heat treatment effect. Larger materials may require longer heating times and slower cooling

Speed to ensure uniform temperature throughout the material. The complex shape of the material may have the problem of stress concentration, need to be more careful to choose the heat treatment process.
