Rockhard 400 Plates

Product Details

Rockhard 400 plates are a type of abrasion-resistant steel plate designed for use in applications where wear and tear are a significant concern. These plates are known for their high hardness and excellent wear resistance, making them ideal for demanding environments. Here are the key features, chemical composition, mechanical properties, and typical applications of Rockhard 400 plates: Key Features: High Hardness: Rockhard 400 plates typically have a hardness of around 400 HBW (Brinell Hardness), providing excellent resistance to abrasion and wear. Durability: The high hardness and toughness ensure a long service life even under harsh operating conditions. Weldability: These plates offer good weldability despite their high hardness, making them suitable for various fabrication processes. Versatility: Available in different thicknesses and sizes to meet a range of application requirements. Standards Compliance: Produced in compliance with relevant standards to ensure consistent quality and performance. Chemical Composition: The typical chemical composition of Rockhard 400 plates includes: Carbon (C): 0.12-0.35% Silicon (Si): 0.10-0.70% Manganese (Mn): 0.70-1.60% Phosphorus (P): ≤ 0.025% Sulfur (S): ≤ 0.015% Chromium (Cr): 0.40-1.00% Molybdenum (Mo): ≤ 0.60% Nickel (Ni): ≤ 0.50% Mechanical Properties: Hardness: ~400 HBW Tensile Strength: Typically around 1250 MPa Yield Strength: Typically around 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 like crushers, screens, and feeders that are subjected to significant wear and tear. Construction Machinery: Ideal for making parts of bulldozers, excavators, and loaders that experience high levels of abrasion. Material Handling: Suitable for chutes, hoppers, and conveyor systems that transport abrasive materials. Agriculture: Used in plows, tillage equipment, and other agricultural machinery that operates in abrasive conditions. Recycling Industry: Applied in shredders, balers, and other equipment that processes recyclable materials and encounters heavy wear. Advantages: Enhanced Wear Resistance: Significantly reduces maintenance costs and downtime due to wear and tear. Cost Efficiency: Long service life leads to cost savings over time. 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 Rockhard 400 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. Rockhard 400 plates are an excellent choice for applications requiring high abrasion resistance and durability.
