Abstract: The hot rolled single sided stainless steel clad plate of 316L stainless steel and Q345C carbon steel was carried out in a hot rolling line by the technology of “electron beam vacuum welding and hot rolling”. High quality single sided stainless steel clad plates were produced by asymmetrical compound billet and asymmetrically rolling. The productions of stainless steel clad plate have reached the requirements of GB/T8165-2008. The interface shear strength is greater than 320 MPa. Hie yield strength is greater than 370 MPa. The tensile strength is greater than 520 MPa. The elongation is greater than 30% , Stainless steel layer and plain carbon steel layer combining degree is good, the composite interface is straight and perfect. A good metallurgical bonding between stainless steel and carbon steel was achieved. The bonding rate reached 100%.
