Abstract: Based on the 2205 duplex stainless steel and Q235B mild steel as the research object, the Gleeble3800 hot simulation experiment machine was used to compress them into a clad plate. The influence law of the final rolling temperature on the microstructure, shear strength and corrosion resistance of the 2205/Q235B duplex stainless steel clad plate was investigated by the optical microscope (OM), scanning electron microscope (SEM), mechanical and electrochemical performance testing. The results showed that, under the certain reduction ratio, 2205 and Q235B could obtain a good bonding interface when the final rolling temperature was within the range of 850—970 ℃. A long austenitic strip was formed on the side of 2205 near the interface, and the decarburization zone with width of 39.1—47.4 μm was formed on the side of Q235B. With the decrease of the final rolling temperature, the shear strength of 2205/Q235B duplex stainless steel clad plate was significantly increased. When the final rolling temperature was 850 ℃, its shear strength was the highest, reaching 445 MPa. With the increase of the final rolling temperature, the δ ferritic content of 2205 duplex stainless steel was increased gradually. The δ ferritic content of the 2205 stainless steel reached the maximum value of 45.3% at 970 ℃, thus leading to the best corrosion resistance of the surface. However, with the increase of the final rolling temperature, the corrosion pit width of carbon steel side at the interface of 2205/Q235B increased from 35.56 μm to 49.44 μm. Therefore, the corrosion protection of the cross-section should be paid attention to.
