Premium Wear Plates for Extreme Abrasion & Impact
Introduction
HARDOX is a globally recognised abrasion resistant steel plate manufactured by SSAB, Sweden. It is engineered for extreme wear, high impact, and demanding service conditions, and is widely used in mining, quarrying, and heavy equipment industries worldwide
HARDOX is a family of quenched and tempered (Q&T) wear plates, designed to deliver a combination of:
• Very high hardness
• Excellent toughness
• Predictable wear life
• Tight thickness and hardness tolerances
HARDOX is typically specified when failure risk, downtime cost, or OEM compliance outweigh material cost considerations.
| HARDOX Grade | Typical Hardness (HBW) |
|---|---|
| HARDOX 400 | 370 – 430 |
| HARDOX 450 | 425 – 475 |
| HARDOX 500 | 470 – 530 |
| HARDOX 550 | 525 – 575 |
Grade selection depends on abrasion severity, impact level, and forming requirements.
• Extremely consistent hardness across plate surface
• High wear life under severe abrasion
• Good toughness despite high hardness
• Global OEM acceptance
• Detailed fabrication and welding guidelines
HARDOX is often used where material performance must be predictable across geographies.
Mining & Quarrying
• Dump truck bodies
• Crusher liners
• Loader and excavator buckets
Heavy Industry
• Wear liners
• Chutes and hoppers
• High-impact material transfer zones
Recycling & Steel Plants
• Scrap handling equipment
• Impact plates
• Severe wear components
| Plate Type | Typical Hardness | Use Case |
|---|---|---|
| TISCRAL | ~350–450 BHN | Severe abrasion |
| JSPL Rockhard | ~400–500 BHN | Severe abrasion + impact |
| HARDOX | 400–550+ BHN | Extreme / OEM-mandated |
HARDOX is selected when global standards, extreme duty, or OEM approvals are required.
HARDOX plates require:
• Strict adherence to SSAB fabrication guidelines
• Controlled cutting and forming methods
• Mandatory preheating during welding
• Approved consumables
Proper fabrication is essential to achieve intended wear performance.
Before ordering HARDOX plates, confirm:
• ✅ Required HARDOX grade
• ✅ Hardness range and thickness
• ✅ Wear severity and impact conditions
• ✅ Fabrication capability and compliance
• ✅ OEM / project specification requirement
Correct specification avoids over-engineering and unnecessary cost.
• Access to genuine HARDOX material
• Honest guidance on when HARDOX is truly required
• Clear comparison with JSPL Rockhard and Indian AR plates
• Ability to supply HARDOX alongside other AR and special steels
We focus on application-correct selection, not brand pushing.
Is HARDOX always required for Indian applications?
No. For most Indian industrial applications, JSPL Rockhard provides sufficient wear life when selected correctly.
When should HARDOX be preferred?
HARDOX is preferred when:
• Global OEMs mandate it
• Extremely severe wear conditions exist
• Downtime cost is exceptionally high
Is HARDOX better than Rockhard?
HARDOX offers tighter global tolerances and OEM acceptance, but Rockhard performs effectively in most Indian conditions.
Can HARDOX be welded?
Yes, but only with strict welding procedures and SSAB-recommended practices.
HARDOX abrasion resistant plates represent the top tier of wear plate performance, designed for extreme conditions and global compliance. However, in most Indian industrial applications, properly selected Indian AR plates such as JSPL Rockhard deliver excellent performance at optimal cost.
At Sharoff Steel Suppliers, HARDOX is supplied with technical honesty, application clarity, and procurement intelligence.
