Confronto tra piastre in acciaio resistenti all'usura NM500 e AR500

NM500 Steel Plate

Origine: NM indica “resistente all'usura” secondo lo standard cinese GB/T24186.
Proprietà:
- Durezza: Tipicamente in giro 500 HBW (Durezza Brinell).
- Resistenza all'abrasione: Eccellente resistenza all'usura e all'abrasione, ideale per applicazioni ad alta usura.
- Forza: Elevata resistenza alla trazione e tenacità.
Produzione: Produced according to the Chinese standard GB/T24186.

Piastra in acciaio AR500

Origine: AR denotes “Resistente all'abrasione” steel grade.
Proprietà:
- Durezza: Generally around 500 Bnn (Numero di durezza Brinell).
- Resistenza all'abrasione: Exceptional resistance to sliding wear and impact.
- Forza: Good strength and toughness characteristics.
Produzione: Typically produced per ASTM International standards, such as ASTM A514 or ASTM A572.
