This paper summarized metallurgical and mechanical properties of stainless steel SUS316L joints brazed with three types of newly developed palladium-copper based filler metals, 30Pd-60Cu-10Co, 30Pd-60Cu-10Ni, 30Pd-50Cu-10Ni-10Co, and commercial nickle-based filler metal Ni-Cr-W-Fe-B-Si. The results obtained were as follows : (1) The maximum joint strength at room temperature was the joint brazed with the palladium-copper based filler metal 30Pd-60Cu-10Co, and the mean value was 536 MPa at the joint clearance range from 0.07 to 0.15 mm.(2) The 30Pd-60Cu-10Co filler metal showed the highest joint strength at 473 K, and the 30Pd-50Cu-10Ni-10Co filler metal showed the highest joint strength at 673 K, 873 K, and 1073 K.(3) Joints brazed with 30Pd-60Cu-10Ni have superior creep rupture resistance at 673K, and the brazed joints with Ni-Cr-W-Fe-B-Si offered longer rupture time at 1073 K than those with palladium-copper base filler matals.
