Technical Specifications
Product Overview
Metallurgical Characteristics
XAR300 features a fine-grained martensitic microstructure achieved through controlled quenching and tempering processes. The optimized chemical composition with controlled carbon content and strategic alloying elements ensures excellent hardenability while maintaining good weldability and machinability characteristics.
Heat Treatment Process
MetalZenith employs a sophisticated heat treatment cycle involving austenitization at 900-950°C, followed by controlled water quenching to achieve uniform martensitic transformation. Subsequent tempering at 200-250°C optimizes the hardness-toughness balance, resulting in consistent 300 HBW hardness throughout the material thickness.
Manufacturing Process
Our advanced production facility utilizes electric arc furnace steelmaking with secondary refining processes including ladle furnace treatment and vacuum degassing. Continuous casting followed by controlled rolling ensures optimal grain structure and mechanical properties. Final heat treatment in computer-controlled furnaces guarantees consistent quality and performance.
Quality Standards & Testing
All XAR300 products comply with international standards including EN 10204-3.1 certification. Comprehensive testing includes chemical analysis by optical emission spectroscopy, mechanical property verification through tensile and impact testing, hardness mapping across the plate surface, and ultrasonic inspection for internal soundness verification.
