Our Products – Rockhard 500 Steel Plates Grades
Rockhard 500 Steel Plates are premium-grade abrasion-resistant steel plates designed for extreme wear and high-impact environments. With a typical hardness of around 500 HBW, these plates provide outstanding resistance to abrasion, cutting, and surface wear, making them suitable for the most demanding industrial applications.
They offer a strong combination of very high hardness, excellent strength, and good toughness, ensuring long service life even under severe working conditions. Despite their high hardness, Rockhard 500 plates maintain acceptable weldability and formability, allowing fabrication into liners, buckets, and structural components.
These plates are widely used in mining equipment, crushers, dump truck bodies, excavator buckets, hoppers, chutes, conveyors, and heavy material handling systems, where maximum wear resistance and reduced downtime are essential.
Rockhard 500 Steel Plates are used in industries where extreme abrasion, impact, and heavy wear conditions are present. These plates are commonly applied in mining equipment, dump truck bodies, excavator buckets, loaders, and earth-moving machinery, where continuous contact with abrasive materials leads to rapid wear.
They are also widely used in crushers, chutes, hoppers, conveyors, and material handling systems, where high friction and constant material flow require long-lasting wear protection. In addition, Rockhard 500 plates are suitable for recycling plants, cement plants, quarry equipment, industrial liners, and heavy-duty transport containers, ensuring durability and reduced maintenance.
Because of their high hardness and wear resistance, Rockhard 500 steel plates are ideal for severe service environments, helping industries improve equipment lifespan, reduce downtime, and increase operational efficiency.
The equivalent grades of Rockhard 500 Steel Plates include Hardox 500, XAR 500, Raex 500, Abrex 500, Dillidur 500V, and Creusabro 4800/8000. These abrasion-resistant steel grades offer similar hardness levels (around 500 HBW) along with excellent wear resistance, toughness, and durability. They are widely used as alternatives in mining, construction, material handling, and heavy engineering applications where extreme abrasion resistance and long service life are required.
Rockhard 500 Steel Plates offer major advantages for industries working in extreme abrasion and high-impact conditions. The biggest benefit is their very high hardness (~500 HBW), which provides superior resistance to wear and significantly extends equipment life.
These plates also provide an excellent combination of high strength and toughness, allowing them to withstand heavy loads and severe impact without early failure. Despite their hardness, they maintain reasonable weldability and formability, making fabrication possible for components like liners, buckets, chutes, and dump bodies.
Another key benefit is reduced maintenance and downtime, which directly improves productivity and lowers operational costs. Their consistent quality and uniform hardness ensure reliable performance in demanding environments such as mining, construction, and material handling. Overall, Rockhard 500 plates are a cost-effective solution for maximum durability and long service life in harsh working conditions.
The chemical composition of Rockhard 500 Steel Plates is carefully designed to achieve very high hardness, excellent wear resistance, and strong toughness for extreme working conditions. It includes controlled amounts of alloying elements such as carbon, silicon, manganese, chromium, nickel, molybdenum, phosphorus, and sulfur.
Carbon (C) is increased to enhance hardness and wear resistance, while manganese (Mn) improves toughness and hardenability. Silicon (Si) supports strength and deoxidation during steelmaking. Strong alloying elements like chromium (Cr), nickel (Ni), and molybdenum (Mo) significantly improve abrasion resistance, impact strength, and overall durability. Phosphorus (P) and sulfur (S) are kept at very low levels to ensure good ductility and prevent brittleness.
| Carbon (C) | Silicon (Si) | Manganese (Mn) | Phosphorus (P) | Sulfur (S) | Chromium (Cr) | Nickel (Ni) | Molybdenum (Mo) |
|---|---|---|---|---|---|---|---|
| Max 0.32% | Max 0.70% | Max 1.60% | Max 0.025% | Max 0.010% | 0.50–1.50% | Max 1.50% | Max 0.60% |
The mechanical properties of Rockhard 500 Steel Plates are designed for extreme wear resistance and high-performance applications in harsh environments. These plates typically offer a hardness range of 470 to 530 HBW, ensuring excellent resistance to abrasion, cutting, and surface wear.
They provide a tensile strength of approximately 1250 to 1600 MPa and a minimum yield strength of around 1200 MPa, allowing them to withstand heavy loads, impact, and continuous stress. The material also offers elongation of about 8% to 12%, which provides limited but sufficient ductility for fabrication processes like cutting, bending, and welding.
These properties make Rockhard 500 steel plates ideal for mining equipment, dump truck bodies, excavator buckets, crushers, chutes, hoppers, and material handling systems, where long service life, reduced maintenance, and maximum wear resistance are essential.
| Property | Value |
