| Abstract: | Based on designing the scheme of chemical compositions by adding Nb-Ti micro- alloying elements and using the thermo mechanical control process, the 700 MPa grade steel for the automotive heavy beam is developed by Angang. The microstructures and the precipitation phases of the steel are analyzed. After that the roll forming test for the steel strip is done. The re sults show that the properties and forming performance of this steel strip are good enough to meet requirements for making the heavy beam of an automobile with high strength. |
