Was wandering whether anyone could suggest how to solder stainless steel. I know hydrochloric acid flux is suggested to remove oxidation. Anyone could suggest a supplier in UK or who would be able to deliver to UK.
The part we have is a folded miniature box (approx. 2x4x3mm). We require to close up 2 gaps of stainless steel material by soldering the surfaces together, however conventional flux does not seem to work...
If anyone has any suggestions on technique or super aggressive flux supplier suitable for this procedure I would be most grateful for advice.
Thanks in advance.
