Technical Specifications
Product Overview
Metallurgical Characteristics
S355MC exhibits a fine-grained ferritic microstructure achieved through thermomechanical controlled processing. The controlled addition of microalloying elements including niobium and titanium promotes grain refinement and precipitation strengthening, resulting in an optimal combination of strength, formability, and weldability essential for structural applications.
Thermomechanical Processing
MetalZenith employs advanced TMCP technology with controlled rolling temperatures between 850-950°C followed by accelerated cooling. This process ensures optimal austenite conditioning and controlled transformation, delivering superior mechanical properties and enhanced formability characteristics compared to conventional hot rolling processes.
Manufacturing Process Excellence
Our state-of-the-art production facility utilizes computer-controlled rolling mills with precise temperature monitoring and automated thickness control. The integrated process includes continuous casting, reheating furnaces with walking beam technology, and multi-stand rolling mills equipped with advanced cooling systems to ensure consistent material properties.
Specialized Quality Testing
MetalZenith conducts comprehensive testing protocols specific to structural steel applications: weldability testing including HAZ toughness evaluation, cold forming assessments with bend and stretch tests, fatigue resistance testing under cyclic loading conditions, and atmospheric corrosion resistance evaluation through salt spray and weathering tests to ensure long-term structural integrity.
Application Engineering Considerations
For building construction and bridge engineering, S355MC provides excellent strength-to-weight ratios and superior weldability for complex structural joints. In automotive applications, the enhanced formability enables complex cold-forming operations while maintaining structural integrity. For machinery manufacturing and general engineering, the consistent mechanical properties and good machinability ensure reliable performance in diverse operating conditions.
