Technical Specifications
Product Overview
Metallurgical Characteristics
CP 600 complex phase steel features a sophisticated microstructure consisting of ferrite, bainite, and small amounts of retained austenite and martensite. This multi-phase composition is achieved through carefully controlled thermomechanical processing, where precise cooling rates and temperature control during hot rolling create the desired phase distribution. The fine-grained microstructure provides excellent strength while maintaining superior formability compared to conventional high-strength steels.
Manufacturing Process
MetalZenith's production process begins with vacuum degassed steel melting to ensure ultra-low inclusion content and precise chemical composition control. The steel undergoes controlled hot rolling with specific finishing temperatures, followed by accelerated cooling on the run-out table. For cold-rolled variants, the material receives controlled annealing in continuous annealing lines with precise temperature profiles to optimize the complex phase microstructure. Advanced process control systems monitor critical parameters throughout production to ensure consistent quality.
Heat Treatment Considerations
CP 600 steel is supplied in the final heat-treated condition and typically does not require additional heat treatment. However, for specific applications requiring stress relief, heating to 150-200°C for 1-2 hours is recommended. Welding operations should utilize low-heat input techniques with preheating to 100-150°C for thick sections. Post-weld heat treatment at 580-620°C may be beneficial for critical applications to optimize the heat-affected zone properties.
Quality Standards & Testing
All CP 600 production adheres to international standards including EN 10338, ASTM A1088, and JIS G3135. MetalZenith's quality assurance program includes continuous monitoring of chemical composition via optical emission spectroscopy, mechanical property verification through automated tensile testing, and microstructural analysis using advanced metallographic techniques. Each coil receives comprehensive certification documenting chemical analysis, mechanical properties, and dimensional compliance. Traceability systems ensure complete product history from raw materials through final delivery.
