Product Description

NM450 Wear Resistant Steel

 

APPLICATIONS:

 

Wear resistant (abrasion resistant) steel is strong steel materials for wear resistant,widely used in the bad working conditions,demanded of high strength,high-wear-resisting performance in engineeing, mining,construction,agriculture,port and metallurgical machinery products. Therefore,solving wear and prolong the used life of mechanical equipment and components becomes the first consideration in the desiging,manufacturing and using. 

 

 Loading machines, dredgers, skip cars, conveying plants, dump trucks, cutting edges, knives, breakers, crushers, sieves, feeders, measuring pockets, journals, buckets, gears, sprockets, loaders industrial trucks, lorries, bulldozers, excavators, slurry pipe systems, screw conveyors, presses etc.
