Recently, flexible nickel-base brazing foil has been prepared by rapid solidification technology. So that it seemed that the brazing, which used the flexible nickel-base brazing foil, is a more effective method for joining having a large joining area than the brazing which uses the powder form nickel-base brazing filler metal. Therefore it seems that the brazing, which uses the nickel-base brazing foil, has been an effective method for producing clad materials. In this study, the clad material which have been brazed with the nickel-base heat resistant alloy; Inconel 600 on AISI304 stainless steel has been produced by the brazing using three types of nickel-base brazing foils. The three types of nickel-base brazing foils are 7Cr(4.5Si-7.0Cr-3.0B-3.0Fe-Nibal.), 5Cr(4.5Si-5.0Cr-3.0B-3.0Fe-Nibal.) and 10Cr(4.5Si-10.0Cr-3.0B-3.0Fe-Nibal.). Brazing was done in an electrical resistant furnace in an argon gas atmosphere. The brazing temperatures employed in this study were 1050, 1100, 1150, 1200 and 1250-degrees-C and the brazing times were 10, 30, 60 and 120 min for all types of brazing foils. The property of the joint was estimated by the mechanical properties, microstructures and distributions of the elements which were investigated by SEM and EPMA. The brazed joint was obtained for all of brazing conditions in this study. The shear strength of the specimen increased with increasing brazing time except at 1050-degrees-C. At 1050-degrees-C, the shear strength of the specimen was not influenced by brazing time. In this case, the break of the specimen during the shear test occurred in the brazed layer. At 1250-degrees-C, the value of 450 MPa was obtained as the maximum shear strength in this study; the break of the specimen occurred in the base metal. The shear strength of the specimen increased with increasing brazing temperature. The shear strength of the specimen increased with increasing chromium content in the brazing foil to 7 mass%.
