Technical Specifications
Product Overview
Metallurgical Characteristics
Spring Steel exhibits a tempered martensitic microstructure achieved through controlled quenching and tempering processes. The high carbon content combined with chromium and vanadium additions provides exceptional elastic properties and fatigue resistance. The fine-grained structure ensures uniform mechanical properties and superior performance under cyclic loading conditions typical in structural applications.
Heat Treatment Process
MetalZenith employs precision-controlled austenitizing at 830-860°C followed by oil quenching and tempering at 400-500°C. This specialized heat treatment cycle optimizes the balance between hardness and toughness while maintaining excellent elastic recovery properties essential for structural performance.
Manufacturing Process
Our advanced manufacturing process includes electric arc furnace melting, continuous casting, and controlled rolling with precise temperature control. Secondary refining ensures low inclusion content and optimal cleanliness, critical for fatigue performance in structural applications. Quality control includes ultrasonic testing and comprehensive mechanical property verification.
Specialized Quality Testing
MetalZenith conducts comprehensive testing including welding performance evaluation using standard procedures, forming capability assessment through bend testing, fatigue strength testing under cyclic loading, and atmospheric corrosion resistance testing in simulated environmental conditions. These tests ensure optimal performance in structural applications.
Structural Application Considerations
For building structures and bridge engineering, Spring Steel provides excellent load-bearing capacity and dynamic response characteristics. In machinery manufacturing and vehicle construction, its superior fatigue resistance ensures long service life under operational stresses. General engineering applications benefit from its combination of strength, elasticity, and formability, making it ideal for complex structural geometries and demanding service conditions.
