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%.

摘要： 釆用“电子束真空焊接制坯+热轧”的工艺在钢厂热连轧生产线上进行了“316L不锈钢+Q345C碳 钢”的单面不锈钢复合板热轧生产。采用非对称制坯及异步轧制的手段生产出了高品质单面不锈钢复合板，所生 产的不锈钢复合板界面剪切强度大于320 MPa、屈服强度大于370 MPa、抗拉强度大于520 MPa、断后伸长率大于 30%,各项指标均达到GB/T8165-2008的要求。不锈钢层和碳钢层结合度良好，复合界面平直，无明显缺陷，不锈 钢与碳钢之间实现了良好的冶金结合，结合率达100% 。
