Brief introduction:
NM400 Steel is a high-strength, wear-resistant steel known for its superior durability and toughness. NM400 is a Chinese GB standard steel grade. The NM 400 material is widely used in industries where resistance to abrasion is important, such as in the construction and mining sectors.
Application:
Wear-resistant spare parts, such as high-efficiency powder selecting wear-resistant parts in cement machinery, mill steel plates, mixer blades, fan blades, mill rollers and so on.
Various wear-resistant conveying pipes, such as powder air conveying system, blast furnace slag system, propeller blades, etc.
Customized welding solutions for completing on-site construction projects, such as silos, chutes, large buckets, etc.
Providing fabrication devices for on-site customized welding repairs to reduce on-site welding workload, such as buckets for work machines and dredging buckets for dredgers.
