Technical Specifications

Product Overview

Metallurgical Characteristics

Plain Carbon Steel exhibits a ferritic-pearlitic microstructure with excellent balance of strength and ductility. The controlled carbon content provides adequate strength for structural applications while maintaining good weldability and formability. The fine-grained structure achieved through controlled rolling ensures uniform mechanical properties and excellent toughness.

Heat Treatment Process

MetalZenith employs controlled hot rolling at temperatures between 1050-1200°C followed by controlled cooling to achieve optimal microstructure. Normalizing treatment at 850-900°C may be applied for enhanced mechanical properties and stress relief, ensuring dimensional stability in structural applications.

Manufacturing Process

Our advanced steelmaking process includes electric arc furnace melting, ladle refining for precise chemistry control, and continuous casting for superior internal quality. The hot rolling process utilizes computer-controlled rolling schedules to achieve consistent mechanical properties and excellent surface quality.

Structural Quality Testing

Comprehensive testing program includes welding performance evaluation using standard procedures, forming capability assessment through bend testing, fatigue strength testing for cyclic loading applications, and atmospheric corrosion resistance testing. All testing follows ASTM and international standards for structural steel applications.

Application Engineering

For building structures, Plain Carbon Steel provides excellent strength-to-weight ratio and weldability for frame construction. In bridge engineering, its reliable fatigue performance and atmospheric corrosion resistance ensure long-term durability. For mechanical manufacturing, the steel offers good machinability and forming characteristics. In vehicle manufacturing, it provides cost-effective solutions for chassis and structural components. For general engineering applications, its versatility and availability make it ideal for diverse fabrication requirements.
