Technical Specifications
Product Overview
Metallurgical Characteristics
IF Steel features an ultra-pure ferritic microstructure with virtually no interstitial carbon and nitrogen atoms. The addition of titanium or niobium as stabilizing elements ensures complete precipitation of residual carbon and nitrogen, resulting in exceptional formability and aging resistance. The fine-grained structure provides excellent deep drawing properties and superior surface quality.
Heat Treatment Process
MetalZenith employs controlled annealing at 650-750°C in protective atmosphere followed by controlled cooling to achieve optimal recrystallization and grain structure. Our continuous annealing process ensures uniform mechanical properties and excellent formability characteristics throughout the coil length.
Manufacturing Process
Our IF Steel production utilizes advanced vacuum degassing technology, precise temperature control during casting, and optimized rolling schedules. MetalZenith's state-of-the-art facilities ensure consistent chemical composition, superior surface quality, and exceptional dimensional accuracy through controlled cooling and tension leveling processes.
Specialized Quality Testing
Comprehensive testing includes deep drawing simulation, Erichsen cupping tests, bend formability assessment, and aging resistance evaluation. Our quality control encompasses weldability testing using various welding processes, forming limit diagram analysis, fatigue strength evaluation under cyclic loading, and atmospheric corrosion resistance testing in simulated environmental conditions.
Application Engineering Considerations
For building construction applications, IF Steel provides excellent formability for complex architectural elements and superior weldability for structural connections. In bridge engineering, the material offers reliable performance under dynamic loading with excellent fatigue resistance. Machinery manufacturing benefits from the steel's consistent forming properties and surface quality, while vehicle manufacturing applications leverage the exceptional deep drawing characteristics for complex body panels and structural components.
