GBT 24186 NM250-NM600 wear-resistant steel Application
GBT 24186 NM250-NM600 steel plates are widely used in heavy-duty structural and wear-resistant applications across various industries. In mining and construction equipment, they are ideal for manufacturing excavator buckets, bulldozer blades, and dump truck liners due to their high hardness and excellent abrasion resistance. In the cement industry, NM400-NM500 grades are commonly used for crusher components, conveyor systems, and raw mill liners where severe wear is a concern.
The material is also applied in quarrying equipment like screening plates and rock drills, as well as in agricultural machinery for harvester blades and plowshares. For infrastructure projects, GBT 24186 NM series plates are used in reinforced structural components requiring both strength and durability. Their reliable performance under high-stress and abrasive conditions makes them a preferred choice for heavy machinery manufacturers and engineering contractors.
