| Abstract: | The development process of 450 MPa high strength weather -proof strip steel is introduced. Its technology is characterized by Nb and Ti microalloying and conrolling and concooling. The products with good weather - proof properties can be obtained by controlling single microstructure. And 450MPa products with each excellent property index can be produced by fine grain strengthening and purification steel controlling. At the same time, the development of a complete set of weld mate- rials and welding process have been also made. |
