Abstract
Peculiarities of structure of seams in thin-sheet stainless steel joints produced by vacuum brazing using copper and nickel alloys as brazing filler metals are considered. Results of metallographic examinations and mechanical tests of the brazed joints are presented. Good prospects for utilisation of brazing filler metals based on the Ni–Mn system are demonstrated for brazing thin-walled structures, in particular, plate-ribbed heat exchangers.
Keywords: vacuum brazing, heat exchanging device, stainless steel, microstructure, brazing filler metal, brazed seam, boron, strength
