Specification

When soldering stainless steel which solder can be used?
Conventional Tin Lead solders can be used for soldering of stainless steel, as well as a high Tin solder such as the Lead Free 99C alloy. It is recommended that the Tin content is greater than 50% to give good bond strength.

What solders are
available?
We stock a 60% Tin 40% Lead blowpipe solder (grade K). Blowpipe are thin sticks of solder approximately 5mm in diameter and 500mm in length. We also stock the Summit Solder range from AIM Solders and the 99C Lead Free on 250g and 500g reels would be suitable and give a good colour match.

Should the flux residues be removed and if so how?
Yes removing of the residues is important. As the flux is acid based removal will prevent discolouration of the metal and any further corrosion. Warm soapy water does the trick.
