01Product Overview & Specifications
NM450 is a high-strength abrasion-resistant steel plate manufactured per the GB/T 24186 Chinese standard. With upgraded hardness and wear resistance compared with NM400, it delivers excellent structural stability and anti-wear performance, effectively improving the durability of heavy mechanical parts and adapting to medium and high-intensity abrasive wear working conditions.
Compared with ordinary carbon steel and low-alloy steel, NM450 features far better comprehensive mechanical properties. Its outstanding wear resistance greatly extends the service life of industrial equipment, reduces part replacement frequency and maintenance costs, and helps enterprises lower overall production losses caused by component wear — a cost-effective and widely accepted wear-resistant material for modern heavy-duty industries.

04Equivalent International Grades
NM450 corresponds to multiple international abrasion-resistant grades, enabling flexible material replacement for global engineering procurement and cross-standard project construction.
Standard System
Equivalent Grade
SSAB Swedish Standard
Hardox 450
American ASTM
AR450
German DIN
DILLIDUR 450V
Note: Although the above grades are equivalent to NM450 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 rapid development of modern industrial technology, high-strength wear-resistant steel has become the core material to reduce economic losses caused by equipment abrasion — NM450 per GB/T 24186 is widely used for heavy-duty industrial wear-resistant components:
Engineering Machinery
Charging cranes, excavator accessories, dumper and truck cargo box wear parts under heavy-load abrasive service.
Material Conveying
Conveyor system wear plates, transfer chute liners and hoppers exposed to continuous material flow.
Processing Tools
Breaking tools, cutting blades and heavy wear-resistant processing parts requiring hardness plus toughness.
Environmental & Recycling
Waste disposal and material recovery equipment wear components — shredder liners and crusher parts.

Q1What is NM450 steel plate?
NM450 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 420–480 HBW hardness, ≥1250 MPa tensile strength and stable mechanical performance for heavy mechanical components.
Q2What is the international equivalent of NM450?
NM450 corresponds to AR450 (ASTM) and DILLIDUR 450V (DIN); SSAB Hardox 450 is its best-known international counterpart. Confirm processing and welding parameters per actual project requirements before material replacement.
Q3What thickness and sizes are available?
NM450 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 NM450?
Per GB/T 24186: tensile strength ≥1250 MPa, Brinell hardness 420–480 HBW, elongation ≥7% (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.
Q6What is the difference between NM450 and NM400?
NM450 delivers upgraded hardness (420–480 HBW vs 370–430 HBW) and higher tensile strength (≥1250 MPa vs ≥1200 MPa) than NM400, adapting to medium and high-intensity abrasive wear working conditions. For parts suffering severe abrasion, upgrading from NM400 to NM450 further extends service life and lowers replacement frequency — both grades are supplied from stock at 3–120mm thickness.
