Product Introduction

nm400 Steel Plates

We learned that NM400 material has the characteristics of high hardness, good wear resistance and high strength. Heat treatment process

The heating, holding and cooling stages in the middle of the material play a crucial role in the performance of the material. Hardness, strength, toughness and impact resistance of NM400 material after heat treatment All have been improved to meet the needs of material properties in different fields. Therefore, NM400 heat treatment is one of the important processes to improve the properties of materials

The application is of great significance.

NM400 heat treatment process

Heat treatment is to obtain the desired organizational structure and properties by controlling the heating, insulation and cooling process of the material. The heat treatment process of NM400 includes heating and protection

Mild cooling in three stages.

1. Heating stage: Put the NM400 material into the furnace, and gradually increase the temperature of the material through the heat energy provided by the heating furnace. The heating temperature should be advanced according to the specific process requirements

Line control, usually 800℃~1000℃.

2. Insulation stage: When the NM400 material reaches the required heating temperature, it needs to keep the temperature evenly distributed for a certain time to ensure the change of the internal structure of the material.

The holding time is generally 1 hour.

3. Cooling stage: Remove the NM400 material from the heat treatment furnace and cool it. There are many kinds of cooling methods, commonly used air cooling and water cooling. Water cools faster, can

It can make the material obtain higher hardness and strength.

NM400 performance after heat treatment

After heat treatment, the properties of NM400 material are significantly improved. It is mainly manifested in the following aspects:

1. Increased hardness: the hardness of NM400 material after heat treatment is significantly increased, usually reaching more than 400HBW, so it has better wear resistance.

2. Strength increase :NM400 material in the heat treatment process, the grain is refined, the structure is more dense, so its strength has also been improved.

3. Toughness improvement: While maintaining the hardness and strength of the NM400 material after heat treatment, the toughness has also been improved to a certain extent, reducing the brittleness of the material.

4. Improved impact resistance: After heat treatment, the impact resistance of NM400 material has been improved, and it can better withstand shock and vibration.
