Technical Specifications
Product Overview
Metallurgical Characteristics
EDD steel features a fine-grained ferritic-pearlitic microstructure optimized for structural applications. The controlled addition of chromium and nickel enhances hardenability and atmospheric corrosion resistance, while maintaining excellent weldability. The balanced chemical composition provides optimal strength-to-weight ratio and superior formability for complex structural components.
Heat Treatment Process
MetalZenith employs controlled rolling at temperatures between 850-950°C followed by accelerated cooling to achieve optimal mechanical properties. The thermomechanical controlled processing (TMCP) refines grain structure and enhances yield strength while maintaining excellent impact toughness and ductility essential for structural applications.
Manufacturing Excellence
Our advanced production process includes continuous casting, controlled rolling, and precision heat treatment with real-time monitoring systems. MetalZenith's quality control ensures consistent mechanical properties, dimensional accuracy, and surface quality throughout the entire production run, meeting the stringent requirements of structural engineering applications.
Specialized Testing Program
EDD steel undergoes comprehensive testing including weldability assessment per AWS standards, forming limit analysis for complex shapes, fatigue strength evaluation under cyclic loading, and atmospheric corrosion resistance testing. Our testing protocols ensure optimal performance in building structures, bridge construction, machinery manufacturing, and automotive applications.
Application Engineering
For building structures, EDD steel provides excellent seismic resistance and load-bearing capacity. In bridge engineering, its superior fatigue strength and atmospheric corrosion resistance ensure long-term durability. For machinery manufacturing and vehicle construction, the combination of high strength and formability enables complex component designs while maintaining structural integrity under dynamic loading conditions.
