Technical Specifications
Product Overview
Metallurgical Characteristics
High Carbon Steel exhibits a predominantly pearlitic microstructure with fine carbide distribution when properly heat treated. The high carbon content (0.60-1.00%) enables significant hardness enhancement through martensitic transformation during quenching, followed by controlled tempering to achieve optimal strength-toughness balance. The microstructural control is critical for achieving superior fatigue resistance and wear properties.
Heat Treatment Process
MetalZenith employs controlled austenitizing at 820-870°C followed by rapid quenching in oil or water to achieve martensitic transformation. Subsequent tempering at 150-650°C allows precise control of final hardness and toughness properties. Our advanced heat treatment facilities ensure uniform heating, controlled cooling rates, and consistent mechanical properties throughout the material cross-section.
Manufacturing Process Excellence
MetalZenith utilizes electric arc furnace melting with secondary refining processes including ladle metallurgy and vacuum degassing to achieve precise chemical composition control and minimize harmful inclusions. Our controlled rolling and forging processes optimize grain structure and mechanical properties, while advanced quality control systems ensure consistent product performance.
Specialized Quality Testing
Our comprehensive testing protocols include forming limit diagram analysis for automotive applications, weldability testing using controlled thermal severity procedures, hydrogen embrittlement susceptibility testing per ASTM F519, and delayed fracture evaluation under sustained loading conditions. These specialized tests ensure optimal performance in high-strength applications where material reliability is critical.
Application-Specific Technical Considerations
For automotive manufacturing, our High Carbon Steel provides excellent spring properties and wear resistance for transmission components. In building structures, the material offers superior load-bearing capacity and fatigue resistance. Bridge engineering applications benefit from high tensile strength and controlled ductility. Lifting equipment applications utilize the material's exceptional strength-to-weight ratio, while pressure vessel applications leverage the high yield strength and controlled toughness properties for safe operation under extreme conditions.
