NM400 wear resistant steel

When it comes to durability, resilience, and strength in the world of steel, NM400 Steel stands tall as a reliable and robust option. In this comprehensive artical, we will delve into the characteristics, applications, advantages, and much more surrounding NM400 . Let’s embark on a journey to understand the intricacies of this exceptional material.

Understanding NM400 Steel

NM400 Steel is a high-strength structural steel known for its exceptional hardness and toughness. It belongs to the family of abrasion-resistant steels, standard GB/T24186, designed to withstand wear and tear in challenging environments. The ‘NM’ in NM400 denotes its abrasion resistance, making it a popular choice in industries where durability is paramount.

Application of NM400 wear-resistant steel plate

It can be used for surface strengthening of various wear-prone equipment components in metallurgical machinery, building materials machinery, electric machinery, mining machinery and other industries. Typical applications include four area:

Provide users with wear-resistant spare parts made of NM400 wear-resistant plates according to design requirements. Such as high-efficiency powder selection wear-resistant parts in cement machinery, mill steel plates, mixer blades, fan blades, mill rollers, etc.
Directly cutting and rolling welding into various wear-resistant conveying pipes.Such as powder air conveying system, blast furnace slag system, propeller blades, etc.
Provide NM400 wear-resistant plates directly to users, who can then cut and weld them to complete on-site construction projects, such as silos, chutes, large buckets, etc.
Based on the wear area of user parts, we provide manufacturing units for on-site tailor welding repairs to reduce the on-site welding workload.Such as the buckets of working machines and the dredgers of dredgers.

Advantages of NM400 wear-resistant steel plate

High wear resistance: Wear tests show that the wear resistance of NM400 wear-resistant plate is 10-16 times higher than that of low carbon steel, 8 times higher than stainless steel and high manganese steel, and 2 times higher than that of cast NM400 wear-resistant plate iron times.
High impact resistance: Due to the use of mild steel substrate, it has high impact resistance, which fully reflects the advantages of both wear resistance and impact resistance of composite materials, which is beyond the reach of cast wear-resistant materials.
Convenient processing performance: not only can it be cold-formed and rolled, it can also be cut by plasma cutting, and the NM400 wear-resistant plate can be quickly welded to the surface of the worn parts.
High-performance price ratio: Although the cost of using nm400 wear-resistant plates increases, taking into account the service life of the machine parts, maintenance costs, shutdown losses, etc., its performance-price ratio is about 2-5 times higher than that of ordinary materials. Due to the reasonable utilization of materials, its price is 45% lower than that of manual surfacing with the same materials.

Conclusion

In the realm of high-strength structural steel, NM400 stands as a testament to innovation and durability. Its exceptional hardness, wear resistance, and versatility make it a top choice for various industries. As we navigate the landscape of steel options, NM400 Steel emerges as a reliable companion, promising longevity and robust performance in the face of adversity.
