Abstract: This paper introduces the test results of various processes for 700 MPa grade high strength steel,analyzes the second phase precipitation process,discusses the high Nb steel recrystallization behavior of different stages,studies effects of rolling process parameters in each process on the second phase precipitation and the influence of mechanical properties,points out the direction of rolling process parameters in each process control.
