Technical Specifications
Product Overview
Metallurgical Characteristics
MIM 4605 features a refined ferritic-pearlitic microstructure with controlled carbide distribution, achieved through precise alloying with chromium, molybdenum, and nickel. This microstructural design provides excellent strength-to-weight ratio, superior weldability, and enhanced atmospheric corrosion resistance essential for structural applications.
Heat Treatment Process
MetalZenith employs controlled normalization at 880-920°C followed by controlled cooling to achieve optimal mechanical properties. For enhanced performance applications, quenching and tempering at 580-620°C provides superior strength and toughness combination while maintaining excellent formability characteristics.
Manufacturing Excellence
Our advanced production process includes continuous casting, controlled rolling with precise temperature monitoring, and accelerated cooling technology. This ensures consistent grain refinement, uniform mechanical properties, and excellent surface quality throughout the entire cross-section.
Structural Performance Testing
Comprehensive quality validation includes welding performance evaluation using AWS D1.1 procedures, cold forming assessments for fabrication suitability, fatigue strength testing under cyclic loading conditions, and atmospheric corrosion resistance testing per ASTM G101 standards, ensuring reliable performance in demanding structural environments.
Application Engineering
For building construction, MIM 4605 provides excellent seismic resistance and fire performance. In bridge engineering, its superior fatigue resistance and weldability enable complex joint designs. For machinery applications, the combination of strength and formability allows for efficient fabrication of complex structural components while maintaining dimensional stability under operational loads.
