Abstract

The stainless steel clad plate was fabricated by vacuum hot rolling. The microstructures and the diffusion of alloy elements at the interface were observed by OM and EPMA. The effects of the hot rolling temperature on the interfacial bonding strength of the clad plate were researched. The results show that C and Fe diffused from the carbon steel to the stainless steel and Cr and Ni diffused from the stainless steel to the carbon steel. Si-Mn-O ternary compound was observed at the interface. The diffusion distance increased with the increasing hot rolling temperature. The microstructure of carbon steel far away from the interfacial was ferrite and pearlite. The microstructure of the carbon steel near the interface was ferrite. The hardness value from the interior of carbon steel to the interface first decreased and then increased. The hardness value from the interface to the interior of stainless steel first increased and then decreased. The lowest (about 121.8HV) and highest (about 245.5HV) values of hardness located in the carbon steel about 40 μm to the interface and stainless steel about 20 μm to interface, respectively. In the range from 1 100 to 1 300 ℃, the interfacial shear strength increased with the increase of rolling temperature. The shear strength of clad plates fabricated at 1 300 ℃ was 463 MPa, which was much higher than that of the carbon steel substrate.
