High Strength Interstitial Free Cold-rolled Steel Coils
High-strength dual-phase steel, a phase change strengthening steel, is in a structure mainly composed of ferrite and martensite, which is dispersed in certain quantity to ferritic matrix by adoption of special chemical compositions and production process. While it gets rained in strength, it gets improved at formability. It is featured with low yield strength, no yield elongation, high strain strengthening index and excellent collision-resistance and can increase safety of automobiles while lowering their weight. It is mainly used for manufacturing wheels,bumpers, suspension systems and reinforcements as well as outside plates of automobiles.
