Technical Specifications
Product Overview
Metallurgical Characteristics
SAE 1005 exhibits a predominantly ferritic microstructure with minimal pearlite content due to its ultra-low carbon composition. The fine-grained structure, achieved through controlled rolling and aluminum deoxidation, provides excellent formability and surface quality. The low carbon content ensures minimal work hardening during cold forming operations, making it ideal for complex structural components requiring extensive deformation.
Heat Treatment Process
MetalZenith employs controlled cooling after hot rolling to achieve optimal microstructure. For enhanced formability, the steel can be subjected to process annealing at 650-700°C followed by controlled cooling. Cold-rolled products undergo continuous annealing at 750-850°C with precise atmosphere control to maintain surface quality and mechanical properties.
Manufacturing Process Excellence
Our production process begins with electric arc furnace melting followed by ladle refining and vacuum degassing to achieve ultra-low carbon levels. Continuous casting with electromagnetic stirring ensures homogeneous composition, while controlled rolling with precise temperature control optimizes grain structure. Advanced surface inspection systems guarantee defect-free products suitable for critical structural applications.
Specialized Quality Testing
MetalZenith conducts comprehensive testing specific to structural applications including Erichsen cupping tests for deep drawing evaluation, 180-degree bend tests for formability assessment, and welding procedure qualification tests. Atmospheric corrosion resistance is evaluated through salt spray testing, while fatigue strength is determined using rotating beam fatigue testing to ensure long-term structural integrity.
Application Engineering Considerations
For building construction applications, SAE 1005's excellent weldability allows for efficient fabrication of structural components with minimal preheating requirements. In automotive manufacturing, the superior formability enables complex panel geometries while maintaining structural integrity. For general engineering applications, the consistent mechanical properties and good machinability facilitate efficient processing and assembly operations.
