Development of 360 MPa Grade Heavy Plate with High Performance

Abstract:

Article Preview

360MPa grade heavy plate with high performance was developed through TMCP technology. By means of tensile and charpy impact tests and optical microscopy, the effects of processing parameters on final microstructure and properties of the steel have been studied, such as start rolling temperature in austenite non-recrystallization region and cooling rate. In order to obtain better mechanical properties, the optimization of the rolling process in an experiment rolling mill has been carried out. It has been found that the tensile strength of HSLA heavy plate are significantly improved by decreasing the start rolling temperature and increasing of the cooling rate, but the impact properties present the reverse law.
