NM550 & NM600 High Hardness Wear Resistant Steel Plates

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 CJM 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.
