Wear Resistance Steel Plate
Wear resistance steel plates are essential materials for industries with high abrasion and impact loads.
When selecting a grade, consider:
-
Hardness and impact toughness;
-
Thickness and dimensions;
-
Origin and standards (international or Chinese equivalents);
-
Processability and weldability.
Chinese grades like NM500, Mn13, CrC/CCO offer cost-effective solutions with high performance, suitable for most industrial applications.
- Description
Wear resistance steel plates are specialized steels designed for high hardness and superior resistance to abrasive and impact wear.
They are widely used in mining, cement, metallurgy, and construction industries for buckets, liners, screw conveyors, hoppers, and crushers.
1. Common International Grades of Wear-Resistant Steel
| Steel Grade | Characteristics | Applications |
|---|---|---|
| NM400 / NM450 / NM500 / NM550 / NM600 | High hardness, optimal balance of strength and ductility | Liners, buckets, screw conveyors, conveyor belts |
| AR400 / AR500 | US grades, hardness HB400–500 | Crushers, transport surfaces |
| Hardox 400 / 450 / 500 / 600 | Swedish brand, high hardness, good weldability | Mining equipment, dump truck bodies |
| Mn13 / Mn18 / Mn22 | High manganese steel, high impact toughness | Crushers, buckets, ore handling lines |
2. Chinese Grades of Wear-Resistant Steel
| Steel Grade | Thickness (mm) | Features | Applications |
|---|---|---|---|
| NM400 / NM450 / NM500 / NM550 / NM600 | 3–100 | Balanced hardness and ductility | Liners, buckets, screw conveyors, conveyor belts |
| HARDOX-style | 4–80 | High hardness HB400–600 | Crushing equipment, construction machinery |
| Mn13 / Mn13Cr | 6–100 | High-manganese steel with high impact toughness | Buckets, crushers, conveyors |
| CrC / CCO (Chrome Carbide Overlay) | 6–50 | Chromium-carbide welded layer, extreme wear resistance | Liners, conveyor belts, mining equipment |
Features of Chinese grades:
-
Manufactured according to GB/T 24186, GB/T 13260 standards;
-
Available in plates, sheets, and coils;
-
Custom welding, cutting, and processing available;
-
Often comparable mechanical properties to international brands, but more cost-effective.
3. Applications of Wear-Resistant Steel Plates
| Industry | Example Parts | Reason for Use |
|---|---|---|
| Mining | Buckets, screw conveyors, crushers | High resistance to abrasive wear |
| Cement | Feed lines, drums, liners | Longevity and reduced replacement costs |
| Metallurgy | Conveyor belts, hoppers, buckets | Resistance to impact and abrasion |
| Construction Equipment | Dump truck bodies, excavator buckets | Protects parts from rapid wear, reduces maintenance |
