Hardox 450 Plate Manufacturer and Supplier

Hardox 450 plate is a quenched and tempered abrasion-resistant steel plate with a nominal hardness of 425 to 475 HBW. This 450 BHN wear plate is made to special standards, ensuring it has a tough outer surface and consistent hardness throughout, engineered for consistent through-thickness hardness.

Hardox 450 Plate composition restricts carbon to a maximum of 0.26%, precisely balanced with manganese, chromium, nickel, and molybdenum to regulate hardenability. The material exhibits high performance with a tensile strength ranging from 1,400 to 1,550 MPa and a yield strength of around 1,250 MPa. Moreover, the minimum elongation is maintained at 10%, guaranteeing essential structural ductility for rigorous engineering applications.

Sachiya Steel International is a certified supplier, stockist, and exporter of Hardox 450 steel plate, with a warehouse in Mumbai, India. With over 20 years of experience and ISO certifications, including 9001, 14001, and 45001, we keep a ready-to-ship inventory of 1,500 to 2,000 metric tonnes in various plate thicknesses.

What sets this grade apart from generic AR450 is the tighter dimensional tolerance, cutting-edge delivery, and primed blasted surface finish that reduces fabrication cost on site. Available thicknesses range from 3 mm to 80 mm, with standard widths up to 2,440 mm and lengths up to 7,315 mm. Custom cutting is available on request. Hardox 450 plate serves wear-critical roles in mining, construction, recycling, agriculture, and transportation. It's also weldable and bendable when the correct procedures are followed.

Hardox 450 Plate Industrial Applications

Hardox 450 wear plate serves 4 major industry sectors where abrasion causes premature equipment failure. The 450 BHN hardness extends component service life 2 to 5 times over mild steel in the same application.

Mining and Quarrying

This plate lines excavator buckets, crusher feed chutes, screen decks, and hopper walls in hard-rock mining operations. Rock and ore abrasion at these contact points wears mild steel within weeks.

Construction and Earthmoving

Hardox 450 steel plate is fitted to bulldozer blades, grader cutting edges, loader bucket floors, and concrete mixer drums. Ground-engaging components benefit directly from the 450 BHN surface hardness.

Recycling and Waste Handling

Shredder liners, sorting screens, and compactor chambers in scrap metal and waste processing facilities use this plate. Mixed waste streams containing metal, glass, and stone create extreme sliding abrasion.

Transportation and Dump Bodies

Dump truck bodies, trailer floors, and tipper bins are a high-volume application for 450 Brinell plate. Reduced plate thickness (compared to mild steel) lowers vehicle dead weight and increases payload capacity.

Is Hardox 450 Plate bendable? +

Hardox 450 plate offers good cold bending properties for an abrasion-resistant grade. Minimum bend radius varies with plate thickness and orientation relative to the rolling direction.

What is the recommended welding procedure for Hardox 450 Plate? +

Select low-hydrogen E70xx or ER70S-6 wire for a robust weld. Preheat the steel between 75 and 200°C, adjusted for thickness, and closely monitor the temperature. Always keep your interpass temperature below 225°C to prevent any structural issues.

How do you drill and machine a Hardox 450 Plate? +

Drilling Hardox 450 requires carbide-tipped tools at reduced speeds with high feed rates and a constant coolant supply. Work hardening occurs rapidly if cutting speed is too high or feed too light.

What is the Rockwell hardness of Hardox 450 Plate? +

Hardox 450 has a Brinell hardness of 425 to 475 HBW, which converts to approximately 45 to 50 HRC on the Rockwell C scale.

How do you calculate Hardox 450 Plate Weight? +

The formula is: Weight (kg) = Length (m) x Width (m) x Thickness (mm) x 7.85. Steel density for this plate is approximately 7,850 kg/m3.

Does Hardox 450 Plate rust? +

Hardox 450 is a low-alloy carbon steel and will corrode without surface protection. It ships in a primed and blasted condition. Additional coating or painting is recommended for corrosive or outdoor environments.

What are the best practices for machining and drilling Hardox 450? +

Hard material requires carbide-tipped tools. Machine slower than mild steel and drill with high feed rate and steady coolant to avoid work hardening. For profiling, switch from mechanical sawing to plasma or oxy-fuel cutting for better efficiency.
