Technical Specifications
Product Overview
Metallurgical Characteristics
Vanadium Steel features a fine-grained ferritic-pearlitic microstructure enhanced by vanadium carbide and carbonitride precipitation. The controlled addition of vanadium (0.05-0.15%) promotes significant grain refinement and precipitation strengthening, 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 vanadium precipitation while maintaining fine austenite grain size, ensuring uniform mechanical properties and excellent structural performance throughout the material cross-section.
Manufacturing Process
Our advanced manufacturing process begins with electric arc furnace melting followed by ladle refining to achieve precise vanadium content and cleanliness. Continuous casting ensures uniform composition, while controlled rolling and cooling optimize the vanadium precipitation sequence for maximum strengthening effect and structural integrity.
Structural Quality Testing
MetalZenith conducts comprehensive testing protocols including welding performance evaluation per AWS D1.1, forming capability assessment through bend testing, fatigue strength testing under cyclic loading, and atmospheric corrosion resistance evaluation. Additional testing includes ultrasonic inspection, magnetic particle testing, and dimensional verification to ensure structural reliability.
Engineering Applications
For building construction, our Vanadium Steel provides excellent strength-to-weight ratios and superior weldability for high-rise frameworks. In bridge engineering, the enhanced fatigue resistance and atmospheric corrosion properties ensure long-term structural integrity. For machinery manufacturing, the fine grain structure and high strength enable compact designs, while in vehicle construction, the excellent forming characteristics and crash performance meet safety requirements. General engineering applications benefit from the versatile combination of strength, toughness, and fabrication ease.
