WIPO Patent Application WO/2016/052738
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a brazing joint having excellent tensile strength (TSS and CTS), and a manufacturing method therefor. A brazing joint is manufactured as follows: after a plate assembly (200) constituted by interposing a filler material (230) between steel plates (210, 220) is heated to at least the Ac3 temperature of the steel plates (base material), and the Ar3 temperature of regions of the steel plates close to the filler material is raised so as to exceed the Ar3 temperature of the steel plates (base material), a hot stamping step, in which a quenching initiation temperature X does not exceed the Ar3 temperature of the steel plates (base material), is performed.
