NM400 Wear Plate (Main Grade for Most Applications)

NM400 wear resistant steel plate is the most widely used grade due to its cost-performance balance.

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 & NM500 Steel Plates for High Abrasion Conditions

For more demanding environments, NM450 steel plate and NM500 wear plate provide higher hardness and longer service life.

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

Using NM500 wear resistant steel plate allows reduced thickness while maintaining durability, improving payload efficiency and reducing equipment weight.

NM400 vs NM500 Wear Plate: How to Choose

Selecting the right wear resistant steel plate depends on application requirements:

• Choose NM400 steel plate for general wear parts and easier fabrication
• Choose NM500 steel plate for maximum wear resistance and longer lifespan
• Choose NM450 plate as a balanced option

For most projects, NM400 wear plate is sufficient, while NM500 steel plate is preferred for high-abrasion environments.

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

NM400 / NM500 Steel Equivalent (Quick Reference)

Applications of NM400 / NM500 Wear Resistant Steel 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.
