JFE 400/450/500 are high-quality abrasion-resistant (AR) steel plates manufactured by JFE Steel Corporation (Japan). Engineered to endure extreme wear conditions, these plates offer excellent hardness, strength, and toughness, making them suitable for a wide range of demanding industrial applications. Key Characteristics: Hardness: JFE 400: 360–440 Brinell Hardness Number (BHN) JFE 450: 420–480 BHN JFE 500: 470–530 BHN Wear Resistance: Designed for prolonged use in abrasive environments, these plates resist both sliding and impact wear effectively. Mechanical Strength: High tensile strength ensures structural reliability and longer life under high load and stress conditions. Weldability: Excellent weldability with proper preheating and heat control, ensuring safe and strong joints without compromising the plate’s properties. Chemical Composition: JFE AR plates typically incorporate a well-balanced mix of alloying elements, including: Carbon (C) Manganese (Mn) Silicon (Si) Chromium (Cr) Nickel (Ni) Boron (B) Plus other micro-alloying elements for enhanced performance Applications: Mining and excavation equipment (e.g., buckets, crushers) Construction machinery and attachments Transportation and industrial containers Agricultural tools and equipment Dump truck bodies, liners, and wear-resistant components Material handling systems such as chutes, silos, and hoppers Benefits: Extended service life in abrasive and impact-heavy conditions Decreased maintenance frequency and cost Improved operational uptime and performance Lightweight options with excellent strength-to-weight ratio Manufacturing: Produced through advanced quenching and tempering processes, JFE AR plates develop a tough, wear-resistant surface with a resilient, high-strength core, optimizing both hardness and durability. Dimensions and Thickness: Available in various thicknesses, widths, and lengths, JFE AR plates can be customized to meet specific industry needs and project specifications.
