NM400 vs Hardox 400 vs AR400: What’s the Best Wear Plate for Your Application?

When selecting wear-resistant steel plates, three names often appear in global searches: NM400, Hardox 400, and AR400. But what exactly sets them apart?

NM400, widely produced in China, is known for its competitive price and reliable hardness (around 400 HB). It is widely used in dump trucks, crushers, and mining equipment.

Hardox 400, developed by SSAB, offers superior consistency, tighter tolerances, and excellent mechanical properties, making it ideal for high-performance applications.

AR400, commonly used in North America, provides a balance between cost and durability, often used in construction and material handling.

For buyers, the choice depends on:

Budget constraints

Required lifespan

Application intensity

If you're sourcing globally, NM400 is often the most cost-effective alternative without sacrificing too much performance.
