ROCKHARD 400 Plate

🛡️ Key Advantages of Rockhard 400 Steel Plates for Heavy Equipment & Wear

Rockhard 400 steel plates are premium abrasion-resistant steel plates designed to perform in the most demanding industrial environments. Produced using advanced quenching and tempering techniques, Rockhard 400 delivers a superior combination of hardness, strength, and toughness—making it the go-to solution for high-impact and high-wear applications.

With rising demand for durable, cost-effective solutions in the mining, construction, and transport sectors, Rockhard 400 continues to lead the way as a reliable, wear-resistant steel plate trusted by engineers and fabricators across India and beyond.

⚙️ What Makes Rockhard 400 Steel Plates Stand Out?

🔸 1. Exceptional Wear Resistance (360–450 BHN)

The core strength of Rockhard 400 steel lies in its surface hardness, rated between 360 to 450 BHN. This high Brinell hardness ensures excellent resistance to abrasion, scraping, and impact, even under harsh field conditions. As a result, it extends the service life of equipment and reduces downtime and maintenance costs.

Typical Applications:

• Stone crushers and screening plants
• Quarry hoppers and chutes
• Excavator and loader buckets
• Truck beds and liners

🔸 2. High Mechanical Strength & Impact Toughness

With a yield strength of up to 1000 MPa and tensile strength exceeding 1100 MPa, Rockhard 400 plates maintain their structural integrity even under dynamic loads and temperature extremes (impact resistance up to -40°C). This makes them a dependable material for heavy-duty industrial environments.

🔸 3. Excellent Weldability

Thanks to its low carbon equivalent, Rockhard 400 allows for easy and safe welding using conventional techniques like MIG, TIG, and arc welding. Fabricators appreciate its consistency during weld operations, with reduced risk of cracks and structural failure.

🏗️ Applications Across Multiple Industries

Rockhard 400 steel plates are engineered for versatility and performance. Their toughness and wear resistance make them suitable for:

🚧 Construction & Earthmoving

• Bulldozers, backhoes, graders
• Loader buckets, cutting edges
• Concrete mixers and drum linings

🏗️ Fabrication & Industrial Equipment

• Hopper liners, feeders, silos
• Chutes and transfer points
• Rotary crushers and shredder liners

🚛 Transportation & Mining

• Tipper trucks, dumper bodies
• Trailer floors, impact beds
• Ore wagons and coal handling systems

🧰 Ease of Processing & Fabrication

Rockhard 400 is not only strong — it’s also easy to process. It can be:

• Cut with plasma, laser, or oxy-fuel
• Formed using press brakes or rolls
• Welded without preheating (in most cases)
• Machined efficiently using high-speed tools

This reduces fabrication time, simplifies project timelines, and enables custom-built solutions for site-specific challenges.

🌱 Sustainable, Efficient, and Future-Ready

As industries move toward more sustainable manufacturing practices, Rockhard 400 steel plates support these goals through:

• Optimized manufacturing processes using controlled cooling and grain refinement
• Reduced material waste due to longer service life
• Recyclable steel composition in compliance with global environmental standards
