Research and Empoldering of High Strength Weathering Steel S450EW
Abstract:
According to the characteristics of high strength weathering steel, this paper designs to develop anexperimental steel S450EW with yield strength higher than 450MPa.Through the study,it has been found that with decreasing cooling rate, the organizational changed largely, while ferrite and pearlite gradually transformed to martensite and a small amount of ferrite, then finally tomartensite organization.It has also been found that the crystal size decreased, and the experimentalsteel also precipitated a rectangular second phase particles of (NbTi) CN phase and TiC, which were sparsely distributed with the size of 100 ~ 300nm and below 30nm, while some phases were distributedasa number of strips in the grain boundary which mainly are C, Fe, Cr.
