Technical Specifications
Product Overview
Metallurgical Characteristics
EN1A is a low carbon structural steel with a predominantly ferritic-pearlitic microstructure. The controlled carbon content and balanced chemistry provide excellent machinability while maintaining adequate strength for structural applications. The fine grain structure achieved through controlled rolling enhances both strength and toughness properties.
Heat Treatment Process
MetalZenith employs controlled hot rolling followed by air cooling or normalization at 850-900°C. This process ensures uniform microstructure and optimal mechanical properties. The controlled cooling rate prevents excessive grain growth while promoting uniform carbide distribution for enhanced machinability.
Manufacturing Excellence
Our advanced manufacturing process includes continuous casting, controlled rolling with precise temperature monitoring, and quality-controlled cooling. MetalZenith's state-of-the-art facilities ensure consistent chemical composition and mechanical properties throughout each production batch.
Structural Performance Testing
EN1A undergoes comprehensive testing including welding performance evaluation using standard procedures, bend testing for formability assessment, rotating beam fatigue testing for structural durability, and salt spray testing for atmospheric corrosion resistance. These tests ensure optimal performance in demanding structural environments.
Application Engineering
For building structures, EN1A provides excellent weldability and formability for complex architectural designs. In bridge engineering, its balanced strength and ductility ensure long-term structural integrity. For mechanical manufacturing, the superior machinability reduces processing costs while maintaining dimensional accuracy. In vehicle manufacturing, the excellent forming characteristics enable complex component fabrication. For general engineering applications, the versatile properties support diverse fabrication requirements.
