XAR 400 / 450 / 500 are premium abrasion-resistant (AR) steel plates manufactured by thyssenkrupp Steel Europe. Known for their exceptional hardness, toughness, and wear resistance, XAR plates are specifically designed to perform in extreme wear environments where mechanical stress, impact, and abrasion are key concerns. Key Characteristics: Hardness Range: XAR 400: 360–440 Brinell Hardness Number (BHN) XAR 450: 420–480 BHN XAR 500: 470–530 BHN Superior Wear Resistance: Excellent protection against sliding and impact abrasion, extending component life in demanding applications. High Strength and Toughness: Maintains structural integrity under heavy mechanical loads and harsh working conditions. Good Fabrication Properties: Can be welded and formed with proper precautions; recommended to use preheating and post-weld treatment for optimal results. Chemical Composition: XAR plates typically include the following alloying elements for enhanced performance: Carbon (C) Manganese (Mn) Silicon (Si) Chromium (Cr) Nickel (Ni) Molybdenum (Mo) Boron (B) Plus other micro-alloys for added strength and stability Applications: Mining and quarrying equipment (e.g., buckets, dump bodies) Construction machinery (excavators, loaders, bulldozers) Cement industry (chutes, silos, hoppers) Recycling and crushing equipment Agricultural and forestry tools Heavy transport and material handling systems Advantages: Extended operational life of components exposed to abrasion Lower maintenance and downtime costs High strength-to-weight ratio Consistent hardness and surface quality Reliable performance in extreme service environments Manufacturing Process: XAR plates are produced via a controlled quenching and tempering process, which results in a homogeneous microstructure with a hard, wear-resistant surface and a tough inner core, ideal for impact and abrasion resistance. Sizes and Availability: Available in a wide range of thicknesses (typically 3 mm to 100 mm or more) and custom dimensions based on project needs. Sheets can be cut to size and processed as required.
