NM400 Wear Resistant Steel
NM400 is a high-strength wear-resistant steel plate, NM400 has a fairly high mechanical strength; its mechanical properties are 3 times to 5 times that of ordinary low alloy steel plate; can significantly improve the wear resistance of machinery-related parts; therefore, improve the service life of machinery; reduce production costs. The surface hardness of this product usually reaches 360～450HB, which is used for processing and manufacturing of wear-resistant wear parts of mining and various engineering machinery and other applicable structural steel plates.

NM400 abrasion resistant steel sheet Products application
NM400 material plate is widely used in areas where durability and wear resistance are essential. Due to its ability to withstand extreme conditions and resist wear, it is commonly used in the manufacture of heavy machinery, mining equipment and tools. Some typical applications include:
Wear-resistant spare parts, such as high-efficiency powder separator wear parts in cement machinery, mill steel plates, mixer blades, fan blades, mill rollers, etc.
Various wear-resistant conveying pipes, such as powder air conveying systems, blast furnace slag systems, propeller blades, etc.
Customised welding solutions for completing on-site construction projects, e.g. silos, chutes, large buckets, etc.
Fabrication units for on-site customised welding repairs to reduce on-site welding workload, e.g. buckets for workhorses and dredging buckets for dredgers, etc.
