What are the main characteristics of NM400 steel?

NM400 steel is a high-strength wear-resistant steel plate. NM400 steel has quite high mechanical strength; its mechanical properties are 3 to 5 times that of ordinary low-alloy steel plates; it can significantly improve the wear resistance of mechanical related parts; thus increase the service life of the machinery; reduce production costs. The surface hardness of the product is usually Reach 360～450HB. Suitable structural steel plates for processing and manufacturing wear-resistant and wearing parts for mines and various engineering machinery.

Main characteristics of NM400 steel

The traditional wear-resistant steel of NM400 steel used in construction machinery is generally high manganese steel. Although high manganese steel has work hardenability, it has strong hardening ability after being subjected to impact stress during its use. Therefore, it can only play its role under a large impact load, and for working conditions with a small impact load, its hardness and wear resistance cannot be improved, and after the high manganese steel is work hardened, its yield strength is not high. Under the action of strong force, the workpiece sometimes cracks, and it is difficult to reach the expected service life. Therefore, compared with high manganese steel, in recent years, low-alloy wear-resistant steel has been used to make small and medium-sized mechanical materials, and it has also been applied in the field of construction machinery, extending and expanding the scope of use of high manganese steel, and has been recognized by the machinery industry. Become a trend.

The characteristics of this product determine the delivery status of the product. To achieve the ideal comprehensive performance, a reasonable delivery status is essential. Wear-resistant steel can obtain good combination of strength and toughness through scientific quenching and tempering process, and can also increase the hardness of steel to achieve the purpose of wear resistance.
