Technical Specifications
Product Overview
Metallurgical Characteristics
Silchrome steel features a refined ferritic-pearlitic microstructure with enhanced silicon and chromium content that provides superior strength and atmospheric corrosion resistance. The controlled silicon content improves deoxidation and enhances the steel's resistance to oxidation, while chromium additions contribute to hardenability and corrosion resistance. The optimized alloy composition ensures excellent weldability without preheating requirements for most structural applications.
Heat Treatment Process
MetalZenith employs controlled rolling at temperatures between 1050-1150°C followed by accelerated cooling or normalization at 880-920°C. For enhanced properties, quenching and tempering at 580-650°C can be applied. Our precise temperature control and cooling rate management ensure optimal grain size and carbide distribution for maximum structural performance.
Manufacturing Process Excellence
Our advanced manufacturing process includes electric arc furnace melting with secondary refining, continuous casting with electromagnetic stirring, and controlled rolling with real-time monitoring. MetalZenith's integrated quality management system ensures consistent chemical composition and mechanical properties throughout production batches.
Specialized Quality Testing
Comprehensive testing protocols include AWS D1.1 welding procedure qualification, bend testing for forming capability assessment, rotating beam fatigue testing to 10? cycles, and salt spray atmospheric corrosion testing per ASTM B117. Additional testing includes ultrasonic inspection, magnetic particle testing, and dimensional verification to ensure structural integrity.
Application Engineering Considerations
For building construction, Silchrome steel provides excellent seismic resistance and fire performance. In bridge applications, the superior fatigue resistance handles dynamic loading from traffic and wind. For machinery manufacturing, the enhanced hardenability allows for selective heat treatment of critical components. Vehicle applications benefit from the improved crash energy absorption and weight optimization potential. General engineering applications leverage the balanced combination of strength, weldability, and machinability for cost-effective fabrication.
