Prime Marine Hot Rolled Colled Rolled St52 St52-3 Wear Resistant Steel Plate Nm400
1. What exactly is NM400 Steel Material?
NM400 Steel is a high-strength, wear-resistant steel with exceptional toughness and endurance. The steel grade NM400 is a Chinese GB standard. The NM 400 material is commonly utilized in industries where abrasion resistance is critical, such as construction and mining.
These abrasion resistant plates, such as NM400 steel, NM450 wear resistant steel plate, and NM500 wear resistant steel plate, have the following characteristics in detail:
Impact resistance: The wear-resistant plate has excellent impact resistance. Even if anything falls from a high location during the conveying operation, it will not do significant harm to the wear-resistant plate like NM400.
Heat resistance: NM 400 wear resistant plates can be utilized ordinarily at temperatures below 600 degrees Fahrenheit. When we add vanadium and molybdenum to wear-resistant plates, we may even utilize such abrasion resistant plates NM400 at high temperatures below 800 degrees.
Corrosion resistance: Because the NM400 wear-resistant steel plate includes a high concentration of Cr, its corrosion resistance is outstanding, and there is no need to worry about corrosion.
Cost-effectiveness: The price of NM 400 wear-resistant plates is typically three to four times that of regular steel plates, but the service life span of wear-resistant plates is more than ten times that of ordinary steel plates, making those NM400 wear resistant plate / sheet highly cost-effective.
Processing is simple: The wear-resistant plate is extremely weldable and can be readily bent into various forms, making it very easy to manufacture.

6. NM400 Steel Forging
Before shaping NM 400 plate / sheet, the material must be heated to a particular temperature. This technique improves the mechanical qualities of the steel, making it more suited for a variety of uses. To retain the integrity of NM400 grade steel, certain forging processes are required.
7. NM400 Wear-Resistant Steel Heat Treatment
To improve the mechanical characteristics of NM 400 sheet, heat treatment procedures including as annealing, normalizing, quenching, and tempering are used. These treatments aid in the attainment of the necessary hardness and strength, hence making NM400 Steel more resistant to wear and strain. However, when it comes to raw materials, we often deliver NM 400 plate in Q+T condition.
8. NM 400 Plate Application
The NM400 material plate is widely utilized in a variety of applications where durability and resistance to wear are critical. Because of its capacity to withstand harsh conditions and resist abrasion, it is often used in the building of heavy machinery, mining equipment, and tools. Typical uses include:
High-efficiency powder choosing wear-resistant components in cement machinery, mill steel plates, mixer blades, fan blades, mill rollers, and so on.
Wear-resistant conveying pipes used in powder air conveying systems, blast furnace slag systems, propeller blades, and other applications.
Custom welding solutions for on-site building projects such as silos, chutes, huge buckets, and so on.
Providing fabrication devices for on-site tailored welding repairs, such as buckets for work machines and dredging buckets for dredgers, to decrease on-site welding effort.
