soldering stainless steel

[old AlParticipant @oldal]

Im with Keith CuP alloys on this. Its not easy and you need the correct stuff to do the job. No short cuts or bodges seem to work , so why try.

bakers fluid is good stuff on the right material, not stainless

As usual, with all things soldering and brazing Keith is always right. Stainless steel does have some challenges when compared to eg brass, copper, mild steel, however you join it, whether soldered, brazed or welded. However, as Keith says using the right materials when coupled with the right techniques and principles will lead to success. A good start is to speak to someone with over 100 years of soldering and brazing experience available to them!

The Stayclean Stainless Liquid Flux supplied by CuP has a proven track record when soldering stainless. It appears to be expensive because it must be shipped by special carrier. Again, as Keith says if you can collect at the exhibitions such as Ally Pally next week you will more or less halve the cost.

Declaration of interest – I now own CuP Alloys.

Looks like another sale coming you way. Haha. Question : Could stainless be silver soldered & would that need any type of flux.

[JasonBModerator @jasonb]

To Silver solder (braze) stainless you would need CuP's HT5 flux or Tenacity No5
