JFE 400/450/500 are premium-grade abrasion-resistant (AR) steel plates developed by JFE Steel Corporation (Japan). Engineered for exceptional performance in high-wear environments, these plates combine hardness, durability, and weldability, making them ideal for heavy-duty industrial use. Key Characteristics: Hardness Range: JFE 400: 360–440 Brinell Hardness Number (BHN) JFE 450: 420–480 BHN JFE 500: 470–530 BHN Outstanding Abrasion Resistance: Built to withstand severe friction and impact, extending the lifespan of components exposed to harsh wear. Superior Strength: Offers high tensile strength, ensuring excellent structural performance under demanding mechanical loads. Weld-Friendly: Can be welded effectively using appropriate techniques; preheating and controlled cooling help retain material integrity and reduce the risk of cracking. Chemical Composition: JFE wear-resistant plates are alloyed with carefully selected elements, including: Carbon (C Manganese (Mn) Silicon (Si) Chromium (Cr) Nickel (Ni) Boron (B) Along with trace elements to enhance toughness and hardness Typical Applications: Mining and earthmoving equipment Construction machinery (e.g., bulldozer blades, loader buckets) Agricultural components and attachments Industrial transport bodies and liners Hoppers, chutes, and conveyors in material handling systems Crusher parts and wear liners Key Advantages: Long-lasting performance in abrasive and high-impact settings Reduced downtime and maintenance expenditure Reliable mechanical strength without excess weight Enhanced productivity and operational efficiency Manufacturing Process: JFE plates undergo a controlled quenching and tempering process, which results in a hard, wear-resistant surface combined with a tough and resilient core — ideal for balancing hardness with durability. Available Sizes: Offered in a wide range of thicknesses and customizable dimensions, JFE AR plates can be tailored to fit the needs of various industries and projects.
