Technical Specifications
Product Overview
Metallurgical Characteristics
SA 414 G is a high-strength low-alloy structural steel with a fine-grained ferritic-pearlitic microstructure. The controlled addition of copper, nickel, and chromium provides enhanced atmospheric corrosion resistance and improved mechanical properties. The optimized carbon content ensures excellent weldability while maintaining high strength characteristics essential for structural applications.
Heat Treatment Process
MetalZenith employs controlled rolling at temperatures between 850-950°C followed by air cooling or normalization at 900-920°C. This process ensures optimal grain refinement and uniform mechanical properties throughout the cross-section. The controlled cooling rate prevents excessive hardening while maintaining the desired strength levels.
Manufacturing Process
Our SA 414 G steel production utilizes electric arc furnace melting with secondary refining processes including ladle metallurgy and vacuum degassing. MetalZenith's continuous casting technology ensures homogeneous chemical composition and minimal segregation, followed by precision hot rolling with computerized process control for consistent mechanical properties.
Structural Quality Testing
Comprehensive testing protocols include welding performance evaluation using standard procedures, forming capability assessment through bend testing, fatigue strength determination under cyclic loading, and atmospheric corrosion resistance testing in simulated environmental conditions. All testing meets ASTM A414 requirements and industry best practices.
Application Engineering Considerations
For building structures, SA 414 G provides excellent strength-to-weight ratios and seismic resistance. In bridge engineering, its superior fatigue resistance and weldability enable complex joint designs. For machinery manufacturing, the material offers reliable performance under dynamic loading. In vehicle construction, it provides crash resistance and structural integrity. General engineering applications benefit from its versatile processing capabilities and consistent quality.
