Why wear-resistant steel
Select for the operating condition, not only the nominal grade.
Wear-resistant steel is used where repeated abrasion, impact or material handling can shorten the service life of ordinary structural plate. The supplied technical material covers a family from NM360 to NM600, with different hardness and strength levels for different working conditions.
Use this page as a technical starting point. Confirm the actual grade, thickness, application, processing method and documentation requirement with the project enquiry before purchase.
Grade framework
Values below are transcribed from the supplied wear-resistant steel product manual and should be confirmed against the final grade certificate and contract.

Applications in the supplied material
Construction machinery
NM400 and NM450 are described for extra-thick structural liner plates, with a stated maximum supply thickness of 150 mm in the reference material.
Coal machinery
NM360, NM400/NM400E and NM450 are described for middle trough and sealing-plate applications in coal machinery.
Harsh wear conditions
NM600 is described for ultra-high-strength wear conditions where replacing worn parts is costly.
Processing & Metallurgical Control
Wear-Resistant Processing Capabilities
Fabrication and heat-treated processing protocols designed to preserve the core hardness and structural toughness of high-grade wear plates.
Precision Flame & Plasma Cutting
Multi-head CNC thermal cutting for heavy plates up to 150 mm thickness, integrated with strict preheating and slow cooling controls to eliminate edge micro-cracking.
