The braze-pressure-welding was conducted for the SUS316L and SUS304L austenitic steel pipes with various total heating time. The BPW's cleaning step was at 1280℃ with keeping time of 60-360s. The forging process was at 1180℃ with keeping time of 0-60s. For the cross section taken from the parts with distance of 0-20mm from the joint interface, the EPR tests were conducted EPR test was conducted to measure the degree of the sensitization of stainless steel. The cross section on the joint interface, the reactivation value was more than 10% indicating that part was sensitized, on the other parts, the values were lower than 1% and no sign of sensitization was suggested.
