Rockhard 400 Steel Plates are abrasion-resistant steel plates designed for applications requiring high wear resistance and durability. With a typical hardness of around 400 HBW, these plates provide excellent protection against abrasion, impact, and surface wear in demanding environments.
They offer a good balance of strength, toughness, and weldability, making them suitable for fabrication processes such as cutting, bending, and welding. Rockhard 400 plates are widely used in mining equipment, construction machinery, dump trucks, loaders, crushers, chutes, and material handling systems, where long service life and reduced maintenance are essential.
Rockhard 400 Steel Plates are widely used in industries where high wear resistance and durability are essential. These plates are commonly applied in mining equipment, dump truck bodies, excavator buckets, loaders, and earth-moving machinery, where components are exposed to continuous abrasion and heavy impact.
They are also extensively used in construction equipment, crushers, conveyors, hoppers, chutes, and material handling systems, helping to extend equipment life and reduce maintenance costs. Additionally, Rockhard 400 plates are suitable for industrial liners, recycling equipment, agricultural machinery, and transport containers, providing excellent resistance to wear in demanding environments.
Because of their balanced properties of hardness, toughness, and weldability, Rockhard 400 steel plates are ideal for heavy-duty applications that require long service life, reduced downtime, and reliable performance.
The equivalent grades of Rockhard 400 Steel Plates include Hardox 400, XAR 400, Raex 400, Abrex 400, and Dillidur 400V. These abrasion-resistant steel plates offer similar hardness levels (around 400 HBW) along with excellent wear resistance, toughness, and durability, making them suitable alternatives for mining, construction, material handling, and heavy engineering applications.
Rockhard 400 Steel Plates offer several advantages for industries requiring high wear resistance and long service life. One of the key benefits is their excellent abrasion resistance, which helps reduce wear and significantly increases the lifespan of equipment operating in harsh environments.
These plates also provide a strong combination of high strength and toughness, allowing them to withstand heavy loads and impact without failure. In addition, they offer good weldability and formability, making fabrication processes such as cutting, bending, and welding efficient and reliable.
Another important benefit is their consistent hardness and uniform quality, ensuring dependable performance across various applications. By using Rockhard 400 steel plates, industries can reduce maintenance costs, minimize downtime, and improve overall productivity, making them a cost-effective solution for heavy-duty and abrasive applications.
The chemical composition of Rockhard 400 Steel Plates is carefully controlled to provide high hardness, excellent wear resistance, and good toughness. The steel typically contains a combination of carbon, silicon, manganese, phosphorus, sulfur, chromium, nickel, and molybdenum, each contributing to its performance in demanding environments.
Carbon (C) enhances hardness and strength, while manganese (Mn) improves toughness and hardenability. Silicon (Si) acts as a deoxidizer and increases strength. Chromium (Cr), nickel (Ni), and molybdenum (Mo) are added to improve wear resistance, impact strength, and durability. Phosphorus (P) and sulfur (S) are kept at low levels to maintain ductility and prevent brittleness.
| Carbon (C) | Silicon (Si) | Manganese (Mn) | Phosphorus (P) | Sulfur (S) | Chromium (Cr) | Nickel (Ni) | Molybdenum (Mo) |
|---|---|---|---|---|---|---|---|
| Max 0.30% | 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 400 Steel Plates are designed to provide excellent wear resistance, strength, and durability in demanding applications. These plates typically have a hardness range of 370 to 430 HBW, ensuring strong resistance to abrasion and surface wear.
They offer a tensile strength of approximately 1000 to 1250 MPa and a minimum yield strength of around 1000 MPa, allowing them to withstand heavy loads and impact conditions. Additionally, the steel provides elongation of about 10% to 15%, which ensures sufficient ductility for fabrication processes such as cutting, bending, and welding.
These properties make Rockhard 400 steel plates suitable for mining equipment, construction machinery, crushers, dump bodies, chutes, and material handling systems, where long service life, reduced maintenance, and reliable performance are essential.
