Wear-Resistant Steel for Moderate Abrasion & Structural Wear
Introduction
SAIL Hard is a wear-resistant steel plate manufactured by Steel Authority of India Limited (SAIL), designed for applications involving moderate abrasion and impact. With a typical hardness of around 200 Brinell (BHN), SAIL Hard bridges the gap between mild steel and high-hardness abrasion resistant plates.
At Sharoff Steel Suppliers, SAIL Hard is supplied for applications where improved wear life over IS 2062 is required, without the fabrication challenges or cost of higher hardness AR plates.
SAIL Hard is a low-alloy, wear-resistant steel produced through controlled rolling and heat treatment to achieve uniform hardness of approximately 200 BHN.
It is not a high-hardness AR plate (like AR 400 or AR 500), but is specifically intended for:
• Structural components exposed to wear
• Moderate abrasion environments
• Applications requiring good weldability and formability
• Typical hardness: ~200 BHN
• Better wear resistance than mild steel
• Good impact tolerance
• Easier fabrication compared to high-hardness AR plates
• Suitable for welding with standard precautions
This makes SAIL Hard a cost-effective wear solution for many industrial applications.
Industrial & Material Handling
• Chutes and liners (moderate wear zones)
• Transfer points
• Conveyor support components
Construction & Equipment
• Bucket side plates
• Equipment bases
• Structural wear parts
Power & Cement Plants
• Coal handling components
• Ash handling structures (non-severe wear zones)
| Parameter | IS 2062 | SAIL Hard |
|---|---|---|
| Typical Hardness | ~140–170 BHN | ~200 BHN |
| Wear Resistance | Low | Improved |
| Weldability | Excellent | Good |
| Cost | Lower | Slightly higher |
| Service Life in Wear | Shorter | Longer |
SAIL Hard is often selected as a step-up from mild steel, not as a replacement for high-hardness AR plates.
SAIL Hard should not be confused with AR 400 / AR 450 / AR 500 grades.
• Use SAIL Hard for moderate wear + fabrication ease
• Use AR 400/450/500 for severe abrasion
Correct selection avoids over-costing or premature failure.
SAIL Hard plates offer:
• Easier cutting and forming than high-hardness AR plates
• Better weldability with standard consumables
• Lower risk of cracking during fabrication
This makes it suitable for fabricators without specialised AR processing facilities.
Sharoff Steel Suppliers supplies SAIL Hard plates in:
• Plates
o Thickness: 5mm to 16mm
o Width: 1250mm
• Cut-to-size sections
All material is supplied with Mill Test Certificates (MTCs).
Before ordering SAIL Hard, confirm:
• ✅ Plate thickness and size
• ✅ Hardness expectation (~200 BHN)
• ✅ Wear severity (moderate, not severe)
• ✅ Fabrication method (cutting / welding / forming)
• ✅ MTC requirement
This ensures correct grade selection and cost efficiency.
• Genuine SAIL-manufactured material
• Clear communication on hardness and suitability
• Guidance on when to upgrade to AR 400 / AR 450 / AR 500
• Integrated supply with structural, engineering, and AR plates
We help customers choose the right wear plate, not just a harder plate.
Is SAIL Hard an abrasion resistant plate?
Yes, but it is designed for moderate abrasion with a hardness of around 200 BHN.
Is SAIL Hard the same as AR 400?
No. AR 400 has significantly higher hardness and wear resistance.
Can SAIL Hard be welded easily?
Yes. It offers better weldability compared to higher hardness AR plates.
SAIL Hard (200 BHN) plates are a practical solution for applications requiring improved wear resistance over mild steel, without the complexity or cost of high-hardness abrasion resistant plates.
At Sharoff Steel Suppliers, SAIL Hard is supplied with honest positioning, proper documentation, and application-based guidance.
