Influence of heat treatment process on properties of NM400 wear-resistant steel

Wear-resistant steel, such as NM400, is an important material used in industry nowadays due to its superior properties. It is highly resistant to wear and abrasion, which is why it is used in many applications that require a high level of durability. The main factor that affects the properties of this type of steel is the heat treatment process. This process can greatly improve the wear resistance and toughness of the steel by allowing for different temperature, pressure, and time settings.
    
Heat treatment is used when working with any type of steel, but it is particularly important for wear-resistant steels like NM400. This steel is usually subjected to some form of heat treatment process to enhance its properties. The most commonly used forms of heat treatment for NM400 steel is normalizing and tempering. Normalizing is a process used to improve the physical properties of the steel, such as strength, ductility, and toughness. The process involves heating the steel to a certain temperature, holding it at that temperature for a certain period of time, and then cooling it.
    
Tempering is the second type of heat treatment process used with NM400. It is used to reduce the hardness and brittleness of the steel while increasing its toughness. It is a process where the steel is heated to a specific temperature and then it is held at that temperature until it is slightly cooled.
    
Both of these processes are used to improve the properties of NM400 wear steel. Normalizing is used to improve the formability, ductility, and toughness of the steel. It also increases the yield strength. Tempering is used to reduce the brittleness and improve the toughness of the steel.
    
To illustrate the effect of heat treatment on the properties of NM400 steel, an image of a graph indicating the hardness of the steel before and after the treatment is included below. As shown, the hardness of the steel increased after heat treatment, indicating that it is more wear resistant than before.
    
Overall, the heat treatment process has a significant impact on the properties of NM400 steel. It can be used to improve strength, ductility, toughness, and wear resistance of the steel. This is why NM400 is so widely used for applications requiring high levels of durability.
