Technical Specifications
Product Overview
Metallurgical Characteristics
S50C exhibits a predominantly pearlitic microstructure with fine carbide distribution when properly heat treated. The medium carbon content provides an optimal balance between strength and ductility, while the controlled manganese content enhances hardenability and structural uniformity. MetalZenith's controlled cooling processes ensure consistent grain size and carbide morphology for superior structural performance.
Heat Treatment Process
MetalZenith employs precision heat treatment cycles including normalization at 850-900°C followed by controlled cooling, or quenching from 820-860°C with tempering at 550-650°C. Our computer-controlled furnaces maintain precise temperature uniformity ±5°C, ensuring consistent mechanical properties and optimal microstructural development throughout the material cross-section.
Manufacturing Process Excellence
Our S50C production utilizes electric arc furnace melting with secondary refining, continuous casting, and controlled rolling processes. Advanced inclusion control and degassing techniques ensure superior cleanliness and structural integrity. Real-time quality monitoring throughout production guarantees consistent chemical composition and mechanical properties.
Specialized Quality Testing
MetalZenith conducts comprehensive testing specific to structural applications: welding performance evaluation including HAZ toughness testing, forming capability assessment through bend tests, fatigue strength determination under cyclic loading conditions, and atmospheric corrosion resistance testing per ASTM standards. These specialized tests ensure S50C steel meets demanding structural engineering requirements.
Structural Application Engineering
For building construction, S50C provides excellent load-bearing capacity with predictable stress-strain behavior. In bridge engineering, the material's fatigue resistance and weldability ensure long-term structural integrity. For machinery manufacturing, the combination of strength and machinability enables complex component fabrication. In vehicle construction, S50C offers optimal strength-to-weight ratios for chassis and frame applications, while general engineering benefits from its versatile processing capabilities and reliable mechanical properties.
