NM400 NM450 NM500 High Manganese Wear-resistant Steel Plate

NM400 wear-resistant steel plate is the most widely used wear-resistant steel plate in mining, construction, and material handling equipment. NM400 steel plate is manufactured using a quenching and tempering process, achieving a reliable balance between wear resistance, toughness, and machinability.

As an experienced exporter, GNEE can reliably supply NM400 wear-resistant steel plates in standard thickness ranges with fast delivery and on-demand cutting. For applications requiring higher hardness and longer service life, we also offer NM450 and NM500 wear-resistant steel plates.

NM500 steel plate  

• NM400 wear-resistant steel plates are suitable for applications requiring good wear resistance and ease of cutting and forming, such as buckets, liners, and general wear parts.
• NM450 wear-resistant steel plates combine hardness and service life, suitable for medium to heavy wear environments.
• NM500 wear-resistant steel plates are designed for harsh wear environments requiring the highest hardness and longer service life, such as crusher liners and dump truck bodies.

Choosing between NM400 and NM500 wear plates depends on wear intensity, fabrication requirements, and cost considerations.

• Select NM400 wear plate for general wear parts requiring easier processing and lower cost
• Select Wear Plate NM500 for maximum wear resistance and longer replacement cycles
• NM450 serves as a balanced option between performance and cost

For most projects, NM400 provides sufficient performance, while NM500 is preferred in high-abrasion environments.

NM-series wear plates are widely used in industries where abrasion resistance is critical:

 Mining Machinery

• Crusher liners and blades: Used for crushing ores and rocks, withstanding high impact and abrasion.
• Conveyor liners and baffles: Protect conveyor belts from erosion by ores and gravel.
• Excavator bucket plates, side blades, and bottom plates: Improve digging efficiency and durability.

 Metallurgical Industry

• Blast furnace hoppers, sintering machine chutes, and continuous casting machine roller conveyors: Withstand high-temperature and high-abrasion environments.

 Cement Industry

• Cheet liners and end bushings: Prevent wear from cement clinker and slag.
• Cyclone dust collector and classifier blades: Improve dust removal and classification efficiency.
• Screw conveyor bottom plates: Protect conveying components.

 ower Industry

• Medium-speed coal mill cylinder liners in thermal power plants: Resistant to coal particle erosion.
• Fan impeller housings and dust collector inlet flues: Resistant to dust abrasion.
• Ash and slag conduits withstand the erosion caused by high-temperature ash and slag.

It supports various processing techniques such as plasma cutting, waterjet cutting, flame cutting, and shearing, and can precisely customize cutting and shaping according to customer drawings and specifications. This effectively reduces subsequent secondary processing steps, significantly shortens the construction cycle, and fully adapts to the supporting needs of mining, construction machinery, and other fields.

FAQ:

1.What is the difference between Hardox 500 and NM500?

Hardness: NM500 typically has a hardness range of around 470-540 HBW (Brinell hardness), while Hardox 500 typically falls within the range of 470-530 HBW. The hardness level indicates their ability to withstand abrasive wear and impact.

2.What is the difference between AR500 and NM500?

AR500: Higher carbon (C: ~0.38–0.45%), chromium (Cr: ~1.5%), and boron (B: 0.0005–0.006%) for enhanced hardness and corrosion resistance . NM500: Lower carbon (C: ≤0.38%), added nickel (Ni: ≤1.0%) and molybdenum (Mo: ≤0.65%) for balanced weldability and toughness .

3.What is a wear resistant plate?

Wear resistant plates are specialized components used in various applications to provide long-lasting wear protection and extend the lifetime of machined parts. They are made from highly durable materials, such as stainless steel, ceramics, and composites, that can withstand extreme friction.

4.What is the hardness of NM500?

With a hardness range of 470-540 HBW, NM500 is widely used in applications where resistance to abrasion is a primary concern, such as in mining equipment, construction machinery, and other heavy-duty applications.
