| Abstract: | The development and process of hot rolled pickled advanced high strength steel (AHSS) in Shougang was introduced. According to the requirements of customers and combined with the production equipment, a serial of hot rolled high strength steels were developed in Shougang, such as dual phase steel, high hole expansion steel, multiphase steel and transformation induced plasticity steel. And the chemical composition and mechanical properties of the high strength steels were analyzed. The microstructural characteristics were described by means of metallographic microscope and scanning electron microscope. Hot rolled pickled advanced high strength steel of Shougang has been widely used in automobile control arms, longitudinal beams and other automobile parts because of its excellent mechanical properties. It will play a greater role in weight reduction and safety of passenger cars in the future. |
