Technical Specifications
Product Overview
Metallurgical Characteristics
XAR500 is a quenched and tempered wear resistant steel with a martensitic microstructure optimized for exceptional abrasion resistance. The steel's composition features controlled carbon content with strategic alloying elements including chromium, nickel, and molybdenum to enhance hardenability and toughness. The fine-grained martensitic structure provides superior wear resistance while maintaining adequate ductility for fabrication and welding operations.
Heat Treatment Process
MetalZenith employs a precisely controlled quenching and tempering process for XAR500 production. The steel is austenitized at 900-950°C, followed by rapid water quenching to achieve full martensitic transformation. Subsequent tempering at 150-250°C optimizes the balance between hardness and toughness. Our advanced heat treatment facilities ensure uniform temperature distribution and consistent mechanical properties throughout the plate thickness.
Manufacturing Process
The production process begins with electric arc furnace steelmaking using premium raw materials, followed by ladle refining and vacuum degassing to achieve optimal cleanliness. Continuous casting produces high-quality slabs which undergo controlled rolling to achieve desired dimensions and microstructure. The final heat treatment process is performed using computer-controlled furnaces with precise temperature monitoring and automated handling systems.
Quality Standards & Testing
MetalZenith's XAR500 production adheres to international quality standards including ISO 9001:2015 and relevant material specifications. Comprehensive testing includes chemical analysis by optical emission spectroscopy, mechanical property verification through tensile and impact testing, hardness mapping across plate surfaces, ultrasonic inspection for internal soundness, and dimensional verification. Each plate is supplied with complete mill test certificates providing full traceability and quality documentation.
