200 BHN to 550 BHN
Introduction
Abrasion Resistant Steel Plates (AR Plates) are specially designed steel plates used in applications where surface wear, erosion, and material loss are the primary causes of failure. Unlike structural or engineering steels, AR plates are selected mainly based on (BHN) rather than yield strength. These come under brand names like SAIL HARD, Uttam HARD, TATA Tiscral, RockHARD, Rockstar and Hardox.
At Sharoff Steel Suppliers, abrasion resistant plates are supplied as a wear-solution product, covering a wide hardness spectrum from 200 BHN to 550 BHN, enabling correct selection based on abrasion severity and impact conditions.
Abrasion resistant plates are and tempered steels engineered to deliver high surface hardness, which significantly improves resistance to:
• Sliding abrasion
• Erosive wear
• Material gouging
• Combined abrasion and impact
Their performance depends primarily on hardness level, plate thickness, and wear mechanism.
| Hardness Range | Typical Application Nature |
|---|---|
| 200–300 BHN | Moderate wear, good formability |
| 350–400 BHN | General abrasion with mild impact |
| 450 BHN | High abrasion, balanced wear & toughness |
| 500–550 BHN | Severe abrasion, low-to-moderate impact |
👉Higher hardness ≠ always better. Correct selection depends on abrasion vs impact balance.
Abrasion resistant plates must be selected based on the type of wear involved:
• Sliding abrasion (low impact) → Higher hardness (450–550 BHN)
• High impact, low abrasion → Engineering alloy steels may be more suitable
• Abrasion with impact → Medium hardness (350–450 BHN)
Incorrect hardness selection can lead to cracking, premature failure, or poor service life.
Mining & Bulk Material Handling
• Chutes and hoppers
• Transfer points
• Crusher liners
Power, Cement & Process Plants
• Coal handling systems
• Ash handling equipment
• Wear liners
Earthmoving & Construction
• Buckets and blades
• Dump truck bodies

Abrasion resistant plates require controlled fabrication practices to preserve hardness and prevent cracking.
Common Cutting Methods
• Plasma cutting
• Laser cutting
• Waterjet cutting
• Oxy-fuel cutting (with controlled heat input)
Fabrication Considerations
• Pre-heating may be required for higher hardness grades
• Controlled welding procedures and consumables are essential
• Excessive heat input should be avoided
• Bending and forming capability reduces as hardness increases
Proper fabrication ensures maximum wear life and structural integrity.

Before ordering abrasion resistant plates, confirm:
• ✅ Required hardness range (200–300 / 350 / 400 / 450 / 500 / 550 BHN)
• ✅ Plate thickness and size
• ✅ Nature of wear (abrasion only or abrasion + impact)
• ✅ Cutting and fabrication method
• ✅ Welding and forming requirements
• ✅ MTC and hardness certification
Correct specification avoids fabrication issues and premature wear failure.
• Supply across a wide hardness range (200–550 BHN)
• Application-based hardness selection guidance
• Cut-to-size solutions for wear zones
• Experience across mining, power, cement, and EPC sectors
We help customers select wear life intelligently, not just buy harder steel.
Is higher BHN always better for wear resistance?
No. Higher hardness improves abrasion resistance but may reduce impact resistance and formability.
Can AR plates be welded?
Yes, but welding requires controlled pre-heating, proper consumables, and procedures.
Can AR plates be cut and bent?
Cutting is possible with appropriate methods. Bending capability depends on hardness and thickness.
Abrasion Resistant Steel Plates (200–550 BHN) are essential for applications where wear resistance directly impacts equipment life and operating cost. Correct hardness selection and fabrication practice are critical to achieving expected performance.
At Sharoff Steel Suppliers, AR plates are supplied with application clarity, fabrication awareness, and reliable sourcing, ensuring long-term value in wear-critical applications.
