Abstract: Austenitic stainless steel composite strips 302/C1 015 were made by using inversion casting method in laboratorial experiments. It was observed in metallographic examination and SEM investigation that the composite strips consisted of three different parts each with different microstructures, i. e. the zone of mother sheet of carbon steel, newly crystallized layers of austenitic stainless steel and transition area between mother sheet and the newly solidified layer. The results of shearing test on the composite strip show that the interfacial shearing intensity can meet the demands of national criterion.
