| Abstract: | Through the effective control over the deformation of the zones of austenite recrystallization and austenite un-recrystallization respectively, the problem of mixture of grains in Nb micro alloyed strip produced in CSP. The high strength strip of QStE380TM used in production of the vertical and transverse beams of trucks is developed by using the technology of Nb and Ti micro alloying. The strip has been proved through the practice to have the good properties of toughness and formality which can meet the requirement of the production of truck beams. |
