| Abstract: | To meet the demand of the domestic pressure vessel industry for roll-bonded clad steel plates,Baosteel has developed an S30403 + Q345R roll-bonded clad steel plate.Comprehensive inspections of the composition,microstructure,and properties are made to systematically evaluate the steel plate in the normalized and normalized + stress relieved states.The results show the cladding interface of the S30403 + Q345R roll-bonded clad steel plate has high shear strength,the base metal has good properties,and the mechanical properties of the steel plate head and tail are uniform.The performance is fully consistent with the technical requirements of the roll-bonded clad steel plate for pressure vessels. |
