GB GCr15 GB/T 18254 Products Description
Forging of NM400 Steels
Forging NM 400 plate / sheet involves heating the material to a specific temperature before shaping it. This process enhances the steel's mechanical properties, making it more suitable for various applications. Proper forging techniques are crucial to maintain the integrity of NM400 grade steel.
Heat Treatment of NM400 Wear-Resistant Steel
Heat treatment of NM 400 sheet involves processes like annealing, normalizing, quenching, and tempering to enhance its mechanical properties. These treatments help in achieving the desired hardness and strength, making NM400 Steel more resilient to wear and tear. But for raw material supplying, we usually supply NM 400 plate in Q+T condition.
Application of NM 400 Plate
NM400 material plate is widely used in extensive applications in areas where durability and resistance to wear are paramount. It is commonly used in the construction of heavy machinery, mining equipment, and tools, owing to its ability to withstand extreme conditions and resist abrasion. Some typical applications are:
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.
