NM600 Steel Plate Description
NM600 wear-resistant steel plate is a high-strength quenched and tempered steel with a nominal hardness of 600 HBW, belonging to the GB/T 24186 standard.
It’s designed for applications where extreme abrasion resistance is required, such as mining, heavy machinery, and material handling equipment.
Compared to NM450 and NM500, NM600 offers significantly higher surface hardness and wear life, making it ideal for use in dump truck bodies, crushers, hoppers, and chutes that endure long-term wear.
Despite its high hardness, NM600 still provides reasonable toughness and weldability when proper preheating procedures are followed.
It’s equivalent to HARDOX 600, DILLIDUR 600V, and JFE-EH600, making it a reliable and cost-effective option for B2B buyers needing high-performance wear steel.

NM600 Applications
NM600 wear-resistant steel plate is widely used in heavy-duty industries that demand maximum hardness and durability.
Typical applications include:
-
Mining machinery: Liners, buckets, dump truck bodies, and crushers
-
Cement plants: Mixers, hoppers, silos, and pipelines
-
Construction equipment: Bulldozer blades, conveyor plates, and feeders
-
Metallurgy and material handling: Wear bars, chutes, and screens
-
Industrial equipment: Impact-resistant and high-friction components
Using NM600 plates significantly extends component life, reduces downtime, and lowers overall maintenance costs, making it an optimal material for extreme wear applications.
