🟧 Product Overview

NM500 / AR500 / Hardox 500 represents the 500‑HBW class of global wear‑resistant steels. This category offers extremely high hardness, excellent impact toughness, and superior abrasion resistance, making it the preferred material for severe wear environments.

• NM500 – Chinese GB/T 24186 standard
• AR500 – International generic abrasion‑resistant steel
• Hardox 500 – Premium Swedish SSAB grade with enhanced toughness

These steels are widely used in mining, construction machinery, heavy‑duty truck bodies, industrial liners, and high‑impact wear components.

🟧 Standards

• GB/T 24186 – Wear Resistant Steel
• SSAB Hardox – Premium wear‑resistant steel
• AR Steel – International abrasion‑resistant steel classification
