Home > Our Products > Wear Resistant Steel Plates > Type / Grade of Wear Plates > RockHard 450 Plate
RockHard 450 Plates are abrasion-resistant steel plates known for their superior hardness (~450 BHN) and enhanced strength properties. Ideal for industries dealing with sliding or impact wear, this grade offers better wear life than standard 400 BHN plates — making it a cost-effective solution where durability is non-negotiable.
At Hindustan Steel Corporation, we offer both RockHard 450 and equivalent alternatives under our premium-grade HIND HARD 450 series — manufactured to meet the expectations of OEMs, contractors, and heavy-duty equipment makers.
RockHard 450 is a quenched and tempered wear-resistant steel with a nominal hardness of 450 BHN. Designed for superior strength and impact resistance, this grade bridges the gap between 400 and 500 BHN plates, offering extended service life without sacrificing weldability or formability.
Key Highlights:
These plates are perfect for industries that require long-term resistance to abrasion and high mechanical loads:
| Grade | Hardness (BHN) | Best Used In |
|---|---|---|
| RockHard 400 | ~400 | Standard sliding wear |
| RockHard 450 | ~450 | Moderate impact + abrasion zones |
| RockHard 500 | ~500 | High-impact, maximum wear areas |
| Sail Hard / Tiscral | ~200–250 | General fabrication, not AR-grade |
| HIND HARD 450 | ~450 | Indian equivalent to RockHard 450 |
We supply HIND HARD 450, a proprietary Indian-manufactured plate that matches or exceeds RockHard 450 in:
Supplied with Mill Test Certificates (3.1 / 3.2), third-party inspection, and full traceability.
| Property | Value Range |
|---|---|
| Nominal Hardness | 425–475 BHN |
| Tensile Strength | 1300–1600 MPa |
| Yield Strength | ~1100 MPa |
| Elongation | 10–14% |
| Thickness Availability | 6 mm to 100 mm |
| Width & Length | Up to 3000mm x 12000mm |
