NM400 Wear Plate (Main Grade for Most Applications)

NM400 wear plate is the most commonly selected grade in the NM series due to its balanced performance and cost efficiency.

It is widely used for:

• Excavator buckets
• Dump truck bodies
• Wear liners and chutes
• General abrasion-resistant structures

Compared with higher hardness grades, NM400 steel plate offers better cutting, welding, and forming performance, making it suitable for fabricated wear parts.

NM450 and NM500 Wear Plates for Higher Wear Resistance

For demanding applications, CJM supplies NM450 and NM500 wear plates with higher hardness levels.

• NM450 wear plate: Suitable for medium to heavy abrasion environments where longer lifespan is required
• NM500 wear plate: Designed for severe wear conditions such as crushers, mining equipment, and high-impact zones

Using NM500 steel plate can reduce plate thickness while maintaining durability, helping improve payload efficiency.

NM400 / NM450 / NM500 Equivalent Grades

To help international buyers, below are common equivalents:

• NM400 wear plate ≈ AR400 steel plate
• NM500 wear plate ≈ AR500 steel plate

If your project follows ASTM standards, you can directly source AR400 / AR450 / AR500 Abrasion Resistant Steel Plate as alternatives.

Chemical Composition of NM400 / NM450 / NM500 Wear Plates

Below are the detailed chemical compositions of NM400, NM450, and NM500 steel plates, ensuring consistent quality and traceability for buyers.

Mechanical Properties of NM Series Wear Plates

Grade	Yield (MPa)	Tensile (MPa)	Elongation (%)	Hardness (HBW)
NM400	≥1230	≥1330	≥15	~400
NM450	≥1340	≥1430	≥9	~450
NM500	≥1600	≥1700	≥10	~500

NM400 vs NM500 Wear Plate: How to Choose

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 NM500 wear plate 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.

Applications of NM400 / NM500 Wear Plates

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

• Mining & Quarrying: Crusher liners, loader buckets, dumper truck bodies.
• Construction: Concrete mixers, bulldozer blades, road paving equipment.
• Material Handling: Coal conveyors, hoppers, chutes, and silos.
• Energy Industry: Power plant coal pulverizers, high-temperature abrasion environments.

Using NM500 wear plate allows thinner plate design while maintaining durability, which can help improve payload efficiency and reduce overall equipment weight.

For practical examples and selection guidance, see NM400 / NM450 / NM500 wear plates for mining and quarry equipment covering crushers, loaders, dump trucks, and bulk material handling systems.
