🟧 Product Overview

NM360 / AR360 / Hardox 400 represents the 360–400 HBW class of global wear‑resistant steels. This category offers a balanced combination of hardness, toughness, and processing performance, making it suitable for medium‑duty wear environments.

• NM360 – Chinese GB/T 24186 standard
• AR360 – International generic abrasion‑resistant steel
• Hardox 400 – Swedish SSAB premium grade with superior toughness

These steels are widely used in mining equipment, loader buckets, dump truck bodies, conveyors, and industrial wear components requiring enhanced service life.

🟧 Standards

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