Rockstar 450 Plates, Thickness: 5 mm

Product Details

Rockstar 450 plates are a type of abrasion-resistant steel plate that offer an excellent combination of high hardness, strength, and durability. They are specifically designed to withstand severe wear and tear, making them suitable for use in challenging environments. Here are the key features, chemical composition, mechanical properties, and typical applications of Rockstar 450 plates: Key Features: High Hardness: Rockstar 450 plates typically have a hardness of around 450 HBW (Brinell Hardness), providing excellent resistance to abrasion and wear. Durability: These plates are engineered for a long service life even in demanding applications. Good Weldability: Despite their high hardness, Rockstar 450 plates maintain good weldability, though appropriate welding techniques and preheating may be required. Versatility: Available in various thicknesses and dimensions to meet diverse application needs. Standards Compliance: Manufactured according to relevant standards to ensure consistent quality and performance. Chemical Composition: The typical chemical composition of Rockstar 450 plates includes: Carbon (C): 0.20-0.30% Silicon (Si): ≤ 0.70% Manganese (Mn): 1.0-1.50% Phosphorus (P): ≤ 0.025% Sulfur (S): ≤ 0.015% Chromium (Cr): 0.40-1.00% Molybdenum (Mo): 0.25-0.60% Nickel (Ni): 0.50-1.0% Boron (B): ≤ 0.005% Mechanical Properties: Hardness: ~450 HBW Tensile Strength: 1250-1450 MPa Yield Strength: Approximately 1000 MPa Elongation: Approximately 10-12% (varies with thickness and specific grade) Impact Toughness: Typically tested to ensure good performance at low temperatures Applications: Mining and Quarrying: Used in equipment such as crushers, screens, feeders, and chutes that are subjected to severe wear and abrasion. Construction Machinery: Ideal for making parts of bulldozers, excavators, loaders, and dump trucks that encounter high levels of abrasion. Material Handling: Suitable for chutes, hoppers, and conveyor systems that transport abrasive materials. Agriculture: Applied in plows, tillage equipment, and other agricultural machinery operating in abrasive conditions. Recycling Industry: Used in shredders, balers, and other equipment processing recyclable materials that experience heavy wear. Earthmoving and Excavation: Parts such as buckets, blades, and wear plates that are constantly exposed to abrasive materials. Advantages: Superior Wear Resistance: Significantly reduces maintenance costs and downtime due to wear and tear. Cost Efficiency: Longer service life leads to cost savings over time, despite the higher initial cost. High Strength: Maintains structural integrity under heavy loads and impacts. Fabrication Flexibility: Good weldability and machinability make it suitable for various manufacturing processes. Considerations: Fabrication: While Rockstar 450 plates offer good weldability, preheating and post-weld heat treatment may be required to avoid cracking and ensure optimal performance. Cost: Higher initial cost compared to standard steel plates, but this is offset by the extended service life and reduced maintenance costs.
