Technical Specifications
Product Overview
Metallurgical Characteristics
X65 is a high-strength low-alloy (HSLA) structural steel with a fine-grained ferritic-pearlitic microstructure enhanced by microalloying elements. The controlled addition of niobium, vanadium, and titanium promotes grain refinement through precipitation strengthening and grain boundary pinning, resulting in an optimal combination of strength, toughness, and weldability essential for structural applications.
Heat Treatment Process
MetalZenith employs thermomechanical controlled processing (TMCP) with controlled rolling temperatures between 850-950°C followed by accelerated cooling. This process optimizes the austenite-to-ferrite transformation, achieving fine grain structure and enhanced mechanical properties without conventional heat treatment, ensuring cost-effective production while maintaining superior structural performance.
Manufacturing Excellence
Our state-of-the-art production facility utilizes advanced continuous casting, controlled rolling mills, and precision cooling systems to ensure consistent material properties. Real-time process monitoring and automated quality control systems guarantee uniform chemical composition and mechanical properties throughout each production batch, meeting the demanding requirements of structural applications.
Specialized Quality Testing
MetalZenith conducts comprehensive testing protocols including welding performance evaluation using standard procedures, forming performance assessment through bend testing, fatigue strength testing under cyclic loading conditions, and atmospheric corrosion resistance testing in simulated environmental conditions. These specialized tests ensure optimal performance in structural applications requiring long-term reliability.
Structural Application Engineering
For building construction and bridge engineering, X65 provides excellent strength-to-weight ratios and superior weldability for complex structural joints. In mechanical manufacturing, the material's consistent properties enable precision fabrication and reliable performance under dynamic loads. For vehicle manufacturing, X65 offers optimal formability and crash resistance. In general engineering applications, the steel's versatility and proven performance make it ideal for diverse structural requirements across multiple industries.
