Wear Resistant Steel Plate
Wear resistant steel plate is high-hardness low-alloy quenched & tempered steel designed to resist abrasion, impact and scratch damage.It is featuring ultra-high surface hardness and long service life. Custom cutting and forming services are supported, widely used in mining, cement, construction machinery and bulk material transportation industries for wear-prone components.
Available Grades
NM400
General-purpose wear resistant plate with Brinell hardness 360–420 HB. Balances abrasion resistance and bending machinability, widely adopted for light-to-medium wear parts such as hopper liners and conveyor side guards.
NM450
Medium-grade wear plate with 400–460 HB hardness, enhanced anti-scouring performance compared to NM400. Ideal for loader buckets, chute liners and cement plant equipment under continuous material friction.
NM500
High-hardness wear steel plate (470–530 HB), outstanding resistance to heavy abrasion and moderate impact. Perfect for mining truck cargo beds, crusher liners and heavy-duty transfer chutes.
NM550
Ultra-high wear resistance grade with hardness ranging from 520–580 HB, excellent for severe abrasive working conditions. Mainly used in large open-pit mining equipment and high-wear crusher wear parts.
Hardox 450
Premium European standard wear plate with stable uniform hardness and good cold bending performance. Preferred for international engineering machinery projects requiring strict quality certification.
Product Features
- Superior anti-abrasion performance: Special alloy formula and QT heat treatment greatly extend service life against sand, ore and gravel friction.
- Balanced hardness & toughness: Resist surface scratching without brittle cracking under medium impact loads.
- Stable uniform hardness: Consistent hardness across the whole plate surface, avoiding partial rapid wear failure.
- Good process adaptability: Supports plasma cutting, flame cutting, bending and conventional welding for component fabrication.
- Wide thickness range: Cover 6mm–100mm, customizable sizes to reduce material waste during secondary processing.
Applications
- Mining Machinery EquipmentManufacture mining truck cargo liners, excavator bucket plates, crusher liners and ore transfer chutes enduring long-term ore friction and impact.
- Cement & Thermal Power PlantsProduce coal hopper liners, ash baffle plates, raw material conveying chute wear liners resisting abrasion from coal, clinker and ash particles.
- Construction & Road MachineryFabricate loader bucket bottoms, asphalt mixer liners and road milling machine wear plates exposed to gravel and concrete friction.
- Port & Bulk Material Conveying SystemUsed for ship unloader hopper liners, conveyor skirt boards and silo wear protection plates for grain, mineral and sand transport.
- Metallurgical & Recycling EquipmentMake scrap metal crusher liners, furnace feeding channel wear plates and waste sorting machinery anti-wear protective components.
Product Advantages
- Extend equipment service cycle: Strong wear resistance reduces frequent part replacement, cutting long-term maintenance and downtime costs.
- Lightweight structural optimization: Higher hardness allows thinner plate design to lower overall equipment weight and transport expense.
- All-in-one processing service: Custom cutting, bending and surface flattening eliminate extra outsourcing processing fees for buyers.
- Stable batch quality: Strict heat treatment control ensures uniform hardness of each batch, avoiding uneven wear on-site.
- Complete grade coverage: From general medium-wear NM400 to ultra-hard NM550, matching different working condition budgets.
- Full export supporting documents: Mill Test Certificate, hardness inspection reports and CE certificates to speed up global customs clearance.
