| Abstract: | This paper investigated the properties,welding procedure,heat treatment and of 2.25Cr-1Mo-0.25V steel,which is a new breed among Cr-Mo steel,through a series of experiments.In the experiments,we used S225V and F537 provided by SAF company in France.The results is obtained:Through studied the properties of 2.25Cr-1Mo-0.25V steel,we determined the manners to choose the welding materials.We chose S225V and F537 as weldingmaterials with which we determined the welding procedure;The ideal preheat temperature is obtained:180℃;The post welding heat temperature is determined and we proved the reasonable by a series of experiments. |
