Technical Specifications
Product Overview
Metallurgical Characteristics
Ultra High Carbon Steel exhibits a predominantly pearlitic microstructure with fine carbide distribution when properly heat treated. The high carbon content (0.60-1.70%) enables exceptional hardness and wear resistance through controlled carbide formation. MetalZenith's precision processing ensures optimal grain refinement and carbide spheroidization for enhanced toughness and workability.
Heat Treatment Process
MetalZenith employs controlled austenitizing at 780-850°C followed by precise quenching and tempering cycles tailored to specific applications. Our advanced heat treatment protocols include spheroidizing annealing for improved machinability and controlled cooling rates to optimize the balance between hardness and toughness for high-strength applications.
Manufacturing Excellence
Our state-of-the-art production facilities utilize electric arc furnace melting with secondary refining processes to achieve precise chemical composition control. Advanced rolling and forming techniques ensure uniform microstructure and mechanical properties throughout the material cross-section, critical for high-strength performance consistency.
Specialized Quality Testing
MetalZenith conducts comprehensive testing protocols specific to high-strength applications including forming performance evaluation using Erichsen and limiting dome height tests, welding compatibility assessment through crack susceptibility testing, hydrogen-induced cracking resistance evaluation, and delayed fracture analysis under sustained loading conditions.
Application Engineering Considerations
For automotive manufacturing, our Ultra High Carbon Steel provides exceptional spring performance and fatigue resistance. In building structures, the material offers superior load-bearing capacity with optimized weight ratios. Bridge engineering applications benefit from excellent tensile strength and fatigue performance under dynamic loading. Heavy lifting equipment utilizes the material's exceptional strength-to-weight ratio, while pressure vessel applications leverage the superior yield strength and crack resistance properties.
