NM 450 Plates Application
NM450 plates, being a wear-resistant steel, are commonly used in various applications where abrasion resistance is required. Some typical applications include:
Mining equipment: Such as buckets, dump trucks, crushers, and excavator parts.
Construction machinery: Components like bulldozer blades, demolition tools, and concrete mixer drums.
Material handling: Chutes, hoppers, conveyor systems, and wear liners.
Agriculture: Tillage equipment, seeders, and harvesters.
Recycling industry: Shredder blades, conveyor belts, and screens.
Forestry: Wood chippers, log splitters, and grapples.
These plates are utilized in environments where there is high wear and abrasion, helping to extend the lifespan of the equipment by offering superior durability and resistance to abrasion.
