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 more demanding working conditions, NM450 and NM500 wear plates provide increased hardness and longer service life.

• Placa de desgaste NM450: Suitable for medium to heavy abrasion environments where longer lifespan is required
• Placa de desgaste NM500: 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.

Mechanical Properties of NM Series Wear Plates

CJM assists buyers in selecting the most cost-effective grade based on working conditions, wear intensity, and fabrication requirements.

• NM400 wear plate is recommended for applications requiring good abrasion resistance with easier cutting and forming, such as buckets, liners, and general wear parts.
• Placa de desgaste NM450 offers a balance between hardness and service life, suitable for medium to heavy abrasion environments.
• Placa de desgaste NM500 is designed for severe wear conditions where maximum hardness and extended service life are required, such as crusher liners and dump truck bodies.

For applications requiring even higher hardness levels, please refer to Placa de acero NM550/NM600 product page.

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 Placa de desgaste 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.
