01Product Overview & Specifications
NM400 is a high-strength wear-resistant steel plate manufactured per the GB/T 24186 Chinese standard, also universally recognized as abrasion-resistant steel plate. Supplied in hot rolled, quenched & tempered (Q&T) condition, it features exceptional wear resistance, outstanding structural strength and stable mechanical performance, effectively enhancing the anti-wear capability of heavy mechanical components.
Compared with ordinary carbon steel and low-alloy steel, the comprehensive mechanical properties of NM400 are 3 to 5 times higher. Excellent wear resistance greatly extends the service life of equipment parts, reduces frequent replacement and maintenance costs, and ultimately lowers the overall production cost for industrial enterprises.

Note: Although the above grades are equivalent to NM400 in core performance, there are slight differences in chemical composition and process performance. It is recommended to confirm processing and welding parameters according to actual project requirements before material replacement.
05Typical Applications
With the high-speed development of technology and modern industry, high-strength abrasion-resistant steel plates effectively reduce the economic loss brought by parts wear — NM400 per GB/T 24186 is mainly used for:
Charging Cranes
Wear liners and structural components for charging cranes under heavy-load, high-frequency abrasive service.
Excavators & Dumpers
Buckets, dump bodies and wear plates for excavators and dumpers handling abrasive ore, sand and gravel.
Conveyers & Trucks
Chutes, hoppers, conveyor liners and truck bodies exposed to continuous material flow and impact wear.
Breaking & Cutting Tools
Breaking and cutting tool components requiring high hardness plus reliable toughness under strong impact.
Waste Disposal & Recovery
Waste disposal and recovery equipment — shredder liners, crusher parts and wear-resistant structures.

Q1What is NM400 steel plate?
NM400 is a high-strength wear-resistant steel plate per the GB/T 24186 Chinese standard, also universally recognized as abrasion-resistant steel plate. It delivers 370–430 HBW hardness, ≥1200 MPa tensile strength and stable mechanical performance for heavy mechanical components.
Q2What is the international equivalent of NM400?
NM400 corresponds to AR400 (ASTM), DILLIDUR 400V (DIN), S460 (EN), IS 2062 E450 BR/D (IS) and SAE J434 Grade D; SSAB Hardox 400 is its best-known international counterpart. Confirm processing and welding parameters per actual project requirements before material replacement.
Q3What thickness and sizes are available?
NM400 plates come in 3–120mm thickness, standard widths 1500 / 1800 / 2000 / 2500mm and standard lengths 6000 / 8000 / 10000mm; custom sizes and shapes are available on request.
Q4What are the mechanical properties of NM400?
Per GB/T 24186: tensile strength ≥1200 MPa, Brinell hardness 370–430 HBW, elongation ≥10% (50mm gauge length) and impact absorbed energy ≥24J at −20°C (longitudinal) — balanced strength, toughness and ductility for long-term heavy-load wear service.
Q5What is your MOQ and delivery time?
MOQ is 1 ton (negotiable). Stock plates ship in 3–7 days; custom production takes 15–30 days depending on sizes and processing requirements.
Q6Why choose NM400 over ordinary carbon steel?
The comprehensive mechanical properties of NM400 are 3 to 5 times higher than ordinary carbon steel and low-alloy steel. Excellent wear resistance greatly extends parts service life, reduces frequent replacement and maintenance costs, and ultimately lowers the overall production cost.
