Technical Specifications
Product Overview
Metallurgical Characteristics
Fe 415 is a microalloyed structural steel with a fine-grained ferritic-pearlitic microstructure. The controlled addition of microalloying elements such as niobium and vanadium promotes grain refinement and precipitation strengthening, resulting in excellent strength-to-weight ratio and superior 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 microstructure for enhanced mechanical properties while maintaining excellent formability and weldability characteristics.
Manufacturing Excellence
Our state-of-the-art production facilities utilize advanced continuous casting and controlled rolling technologies to ensure uniform chemical composition and mechanical properties. Real-time process monitoring and automated quality control systems guarantee consistent product quality meeting the most demanding structural engineering requirements.
Specialized Quality Testing
MetalZenith conducts comprehensive testing protocols including welding performance evaluation using standard procedures, forming capability assessment through bend and cup tests, fatigue strength testing under cyclic loading conditions, and atmospheric corrosion resistance testing to ensure long-term structural integrity in various environmental conditions.
Application Engineering Considerations
For building construction applications, Fe 415 provides optimal strength-to-weight ratios enabling efficient structural designs. In bridge engineering, its excellent fatigue resistance ensures long-term performance under dynamic loading. For machinery manufacturing, superior weldability facilitates complex fabrication processes. In vehicle manufacturing, the combination of strength and formability enables lightweight yet robust structural components. General engineering applications benefit from its versatility and reliable performance across diverse operating conditions.
