Technical Specifications
Product Overview
Metallurgical Characteristics
SPCC steel features a fine-grained ferritic microstructure achieved through controlled cold rolling and annealing processes. The low carbon content and optimized chemistry provide excellent formability and weldability, while the cold-worked structure offers enhanced strength and dimensional stability essential for structural applications.
Heat Treatment Process
MetalZenith employs continuous annealing at 650-750°C in controlled atmosphere furnaces, followed by controlled cooling to achieve optimal mechanical properties. This process eliminates work hardening from cold rolling while maintaining fine grain structure for superior formability and surface quality.
Advanced Manufacturing Process
Our SPCC production utilizes multi-stand tandem cold rolling mills with advanced gauge control systems, ensuring thickness tolerance within ±0.02mm. The integrated pickling and cold rolling line removes scale and contaminants, while precision tension control maintains optimal mechanical properties throughout the coil.
Structural Quality Testing
MetalZenith conducts comprehensive testing including welding performance evaluation using standard procedures, formability assessment through Erichsen cupping and bend tests, fatigue strength testing under cyclic loading, and atmospheric corrosion resistance evaluation in salt spray chambers to ensure long-term structural integrity.
Application Engineering Considerations
For building structures, SPCC provides excellent forming characteristics for complex architectural elements. In bridge engineering, its consistent mechanical properties ensure reliable performance under dynamic loads. Automotive applications benefit from superior surface finish and formability, while machinery manufacturing utilizes its dimensional accuracy and weldability for precision components.
