Comparison of NM500 and AR500 Wear-Resistant Steel Plates

NM500 Steel Plate

Origin: NM indicates “wear-resistant” per the Chinese standard GB/T24186.
Properties:
- Hardness: Typically around 500 HBW (Brinell Hardness).
- Abrasion Resistance: Excellent wear and abrasion resistance, ideal for high-wear applications.
- Strength: High tensile strength and toughness.
Manufacture: Produced according to the Chinese standard GB/T24186.

AR500 Steel Plate

Origin: AR denotes “Abrasion Resistant” steel grade.
Properties:
- Hardness: Generally around 500 BHN (Brinell Hardness Number).
- Abrasion Resistance: Exceptional resistance to sliding wear and impact.
- Strength: Good strength and toughness characteristics.
Manufacture: Typically produced per ASTM International standards, such as ASTM A514 or ASTM A572.

Key Comparisons
