Key Features
Extreme Wear Resistance
15-20x longer lifespan than mild steel, 5-10x outperforming low-alloy steel, and 2-5x superior to high-chromium cast iron.
Hardness up to 415 HBW (NM400 grade) with customizable NM450/NM500 options for severe abrasion.
Impact-Tough Design
35-42J impact energy at -20°C (AKV tested) resists cracking under dynamic loads.
Bimetal structure: Hard alloy surface (1233MPa yield strength) + ductile substrate (1337MPa tensile strength).
High-Temperature Resilience
Stable performance ≤600°C; ≤800°C with vanadium/molybdenum alloys.
Anti-Corrosion Protection
High chromium content (≥15%) in alloy layer fights rust and chemical wear.
Easy Fabrication
Cut, weld, bend, punch-ready – ideal for buckets, liners, and conveyor parts.
These features make NM400/NM450/NM500 steel plates the material of choice for construction, quarrying, and heavy transport industries.

FAQs
What is the difference between NM400 and NM500 wear plates?
NM500 wear plate has higher hardness and abrasion resistance compared to NM400 wear plate, making it suitable for more extreme environments.
Are NM500 plates suitable for high-impact applications?
Yes. NM500 combines hardness with toughness, performing well under both abrasion and impact conditions.
What is the difference between AR500 and NM500?
AR500: Higher carbon (C: ~0.38–0.45%), chromium (Cr: ~1.5%), and boron (B: 0.0005–0.006%) for enhanced hardness and corrosion resistance . NM500: Lower carbon (C: ≤0.38%), added nickel (Ni: ≤1.0%) and molybdenum (Mo: ≤0.65%) for balanced weldability and toughness .
