ABSTRACT:
A method for brazing two or more of stainless steel components for use in medical equipment, in which one component is joined to other component using a brazing material containing Au of which amount is 62.5 wt % or higher, the method comprising the steps of: a first step in which the components are subjected to a heat treatment at a temperature of 1,050 to 1,200° C. in a hydrogen containing atmosphere or in a vacuum; a second step in which one of the components is allowed to close to the other component so as to form a gap therebetween; and a third step in which the brazing material in a molten state is supplied into the gap to join the components together to manufacture a metal assembly. The joint portions formed in the metal assembly have excellent chemical resistance and corrosion resistance, and thus the metal assembly is suitably used in an endoscope.
