JH-004BXG Reihen-Edelstahl-Lötmittel ohne ätzenden Fluss

Research background
Recent year, stainless steel tube with thin tube wall widely used in household electric appliance refrigeration industry. But traditional stainless steel pipe welding has 3 disadvantages.
1The price is much high to using the silver solder
2If you use Corrosive solder flux, Once it enter into pipe which will easy cause solder Corrosion
3Solder welding temperature is high, because the stainless steel tube wall is thinner, very easy oxidation, especially the pipe internal wall, the black oxide skin is difficultly to remove
For a few decades, domestic and foreign experts in brazing technology research, has been in the pursuit for stainless steel low temperature no corrosion solder technology solutions, but ineffective
Jinghang brazing technology R&D team have broken the world top problem after several years effort. The stainless steel solder with no Corrosive flux can be welded in this temperature arrange: 380~450degree, the brazing performance is excellent, easily operate with low brazing temperature advantage. It is wildly applied in brazing of different stainless steel pipe.
Character
1. Stainless steel solder with no Corrosive flux
Alloy system is composition of Sn-AG rare earth quaternary alloy, brazing temperature: 380-450degree
Can be made into diameter of 1.0-3.0 brazing rod. The rod own strength is 300MPa-400 MPa It can be changed according to its manufacturing hard degree.
2. Brazing performance
JH-004BXG brazing filler metal by flame brazing and high frequency brazing heating, it has good extension performance in stainless steel surface; It has good seam filling performance when weld the stainless steel tube wall. As the filler metal melt temperature is below 450degree, its melt temperature much lower than high silver filler metal (melt temperature 680degree). So in brazing, the stainless steel base metal is not soft. To avoid the brazing welding stress and tiny cracks which highly improve the air tightness.
