Technical Specifications
Product Overview
Metallurgical Characteristics
DP980 features a sophisticated dual-phase microstructure consisting of a soft ferrite matrix (75-85%) reinforced with hard martensite islands (15-25%). This unique microstructural arrangement provides exceptional work hardening behavior and continuous yielding characteristics, essential for complex forming operations in structural applications. The fine-grained ferrite matrix ensures excellent ductility while the dispersed martensite phase contributes to high strength and energy absorption capacity.
Heat Treatment Process
MetalZenith employs controlled intercritical annealing at 750-820°C followed by rapid cooling to achieve optimal dual-phase microstructure. Our continuous annealing line features precise temperature control and atmosphere management, ensuring consistent austenite formation and subsequent martensite transformation. The cooling rate is carefully controlled to prevent bainite formation and achieve the desired ferrite-martensite balance.
Advanced Manufacturing Process
Our DP980 production utilizes advanced hot rolling with controlled finishing temperatures, followed by optimized coiling and subsequent cold rolling to achieve precise thickness tolerances. The critical intercritical annealing process is performed in our state-of-the-art continuous annealing furnace with hydrogen-nitrogen atmosphere control, ensuring uniform heating and controlled cooling for consistent microstructural development.
Specialized Quality Testing
MetalZenith conducts comprehensive testing specific to structural applications including resistance spot welding evaluation, hole expansion testing for formability assessment, high-cycle fatigue testing under variable amplitude loading, and salt spray corrosion testing per ASTM B117. Advanced microstructural analysis using SEM and EBSD ensures optimal phase distribution and grain refinement for superior structural performance.
Structural Application Engineering
For building construction and bridge engineering, DP980's high strength-to-weight ratio enables lighter structural designs while maintaining safety factors. In automotive manufacturing, the excellent crash energy absorption and formability support complex component geometries. For machinery applications, the superior fatigue resistance and weldability ensure long-term structural integrity under dynamic loading conditions. Our technical team provides application-specific guidance for joint design, forming parameters, and structural optimization.
