Wear-resistant steel plates, in layman's terms, are impact-resistant and wear-resistant steel plates. Wear-resistant steel plates are mainly used in equipment manufacturing companies such as coal mines, mining, cement, environmental protection, and engineering machinery, such as crushers, vibrating screens, mining dump trucks, excavator buckets, and cement mixing equipment.
Application of Wear-Resistant Steel Plates in Actual Production
Loader blades are constantly subjected to sliding wear and impact wear from ore and gravel, damaging their overall strength and potentially rendering the loader inoperable. Therefore, higher surface hardness is the fundamental reason why more and more manufacturers are upgrading key parts to wear-resistant steel plates. Q550D, a high-strength structural steel suitable for load-bearing components (frames and booms), is commonly used. Its hardness typically ranges from 170–220, making it highly susceptible to damage in highly abrasive conditions.
NM400/NM500, low-alloy wear-resistant steels, combine high strength, high hardness, and long wear life.
NM400: HBW ≈ 370–430
NM500: HBW ≈ 470–530
