NM400 wear plate is the most widely used abrasion resistant steel plate for mining, construction, and material handling equipment. Designed through quenched and tempered processing, NM400 steel plate provides a reliable balance between wear resistance, toughness, and fabrication performance.
As an experienced exporter, CJM supplies NM400 wear plates in stable stock with standard thickness ranges, fast delivery, and cut-to-size processing. For applications requiring higher hardness and longer service life, NM450 and NM500 wear plates are also available.
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.
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.

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.
NM450 wear plate offers a balance between hardness and service life, suitable for medium to heavy abrasion environments.
NM500 wear plate 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 NM550/NM600 Steel Plate 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 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.
