Technical Specifications
Product Overview
Metallurgical Characteristics
CP 1000 features a complex multiphase microstructure consisting of ferrite, bainite, martensite, and retained austenite phases. This unique microstructural combination is achieved through controlled thermomechanical processing and precise cooling strategies. The fine-grained microstructure provides excellent strength while the retained austenite enhances ductility through transformation-induced plasticity (TRIP) effects.
Heat Treatment & Processing
MetalZenith employs continuous annealing with intercritical heating at 750-820°C followed by controlled cooling to achieve optimal phase distribution. The processing includes hot rolling at 1100-1200°C, controlled cooling, pickling, cold rolling with 50-80% reduction, and final annealing. Precise temperature control and cooling rates are critical for achieving target mechanical properties.
Manufacturing Process Control
Our integrated production line features real-time monitoring of rolling forces, temperatures, and cooling rates. Advanced process control systems ensure consistent microstructural development and mechanical properties. Statistical process control with continuous feedback loops maintains tight tolerances on chemical composition and processing parameters.
Quality Standards & Testing
All CP 1000 products undergo comprehensive testing including tensile testing per ASTM E8, hardness testing per ASTM E18, microstructural analysis, and formability testing. Quality management systems comply with ISO 9001:2015, IATF 16949, and industry-specific standards. Material certificates include chemical analysis, mechanical properties, and dimensional verification data.
