Product Description
NM550 / NM600 Steel Plate belongs to a premium category of high hardness wear-resistant steels, widely used in applications where extreme abrasion and high impact resistance are required. These plates are quenched and tempered (Q+T) to achieve excellent hardness, strength, and durability, especially in mining, construction machinery, and industrial equipment.
At GNEE Steel, we supply NM550 and NM600 plates that meet or exceed Chinese GB/T 24186 standards, and are compatible with Hardox 550 / 600 and JFE EH500 / EH600 equivalents. Whether you're sourcing for crusher liners, bulldozer blades, excavator buckets, or heavy-duty dump truck bodies, these high-performance materials ensure long service life and reduced maintenance.
Why Choose NM550 / NM600 Wear Resistant Steel?
Superior hardness: Up to 600 HBW for excellent wear resistance
High strength: Yield strength above 1200 MPa
Reliable toughness: Maintains impact resistance at low temperatures
Custom cutting: Plasma, laser, and flame cutting available
Global supply: Exported to Southeast Asia, South America, Africa, and Middle East
