【Abstract】 The possibility and necessity of substituting RSCA for cold - rolled steels are introduced. The microstructures, chemical compositions and mechanical properties of RSCA and 08Al are studied through the experiments. Pressing property of two materials and parts’ surface quality are compared. Experiments’ results show that it is possible using RSCA to produce some automotive parts.更多还原
