Understanding Wear-Resistant Steel Plate Classifications
Wear-resistant steel plates are categorized by hardness, alloy composition, and manufacturing processes. The most common classification systems include:
- Brinell Hardness (HB): Ranges from HB 400 to HB 600, with higher values indicating greater abrasion resistance.
- ASTM Standards: Such as ASTM A514 for quenched and tempered alloys.
- EN Standards: Like EN 10025 for structural steel grades.
For example, AR400 plates (abrasion-resistant) are ideal for mining equipment, while Hardox 500 suits heavy-duty construction machinery.
Key Material Properties
| Property | Impact on Performance |
|---|
| Hardness | Directly correlates with wear resistance |
| Toughness | Prevents cracking under impact |
| Weldability | Affects fabrication flexibility |
Common Types of Wear-Resistant Plates
1. Quenched & Tempered Plates
These undergo heat treatment for uniform hardness. Examples include:
- JFE Everhard (Japan)
- DILLIDUR (Germany)
2. Composite Overlay Plates
Feature a hardened surface layer bonded to a tough substrate, offering cost efficiency for moderate-wear applications.
Standard Specifications & Dimensions
Typical dimensions vary by application:
- Thickness: 3mm to 150mm
- Width: 1,500mm to 3,500mm
- Length: 6,000mm to 18,000mm (custom cuts available)
Industry-Specific Requirements
Mining: Thicker plates (≥50mm) for chutes and crushers. Agriculture: Medium thickness (10-30mm) for harvester components.
Selection Criteria for Technical Evaluators
- Assess operational stress (abrasion vs. impact)
- Verify compliance with ISO 15601 or DIN 24588
- Compare lifecycle costs (initial price vs. replacement frequency)
