I need to solder a cylinder of stainless to a brass ring under an inch on both. Question is will Brownells silver solder and flux work. I have both hi temp as well as the lower with fluxs for both. Has any one used these??

How about plain old flux coated Brass Brazing rod

No.
However, a quick google tells you special acid flux is needed to join SS to brass.
Silvaloy and UltraFlux sounds like your best combo at Brownells.

Thanks I have ordered the correct flux and we will see what happens.

I would use Harris Ag56 And the appropriate flux from your local welding supply.

It is about as low temp as silver"hard" solders go and matches the color of Stainless steel, it also flows really well and flows amazingly between close fitted parts

Once I learned I had to brush it onto the surface of the stainless to achieve tinning, it went very well. I thought the Brownells Hi Force 44 matched the stainless barrel just fine.

tsturm,

Get a Clue!


I'll place a $1000 bet on that procedure that it ends in disaster.

Silver Brazing is elementary in comparison.

From looking at your website You definitely


know all about disaster

defiantly or definitely????????????????????

I have had the best luck with 45% silver solder. A touch of feather in the flame and lots of paste flux of the correct type for the solder. You have to be careful not to let the stainless blacken.

O.K. 1st are we talking about soldering or brazing? To solder S/S you will need a flux that is geared to use on S/S or C/u along the lines of "Sure Bright". If brazing or heliarking we use in the industry a product called silfos;basically a silver solder rod that we use to seal refrigerent lines.That does not require a fluxing agent. I think you mean the latter,but they do make a paste if required.

I'm referring to silver solder with a working temp. of approx 1100 degrees. It's been awhile but the paste flux is a white paste that wets out in the same temp range as the solder. The wire I got was 1/16" coil. The only brazing material (1700 deg) that would come close to doing a good job was nickel silver rod. Allstate #11 or Welco #17. The 45% was only available cadmium free for the food service industry.
