For instance, our No. 71 (link) is excellent for soldering stainless steel, exhibiting great results with even the simple eutectic solders such as Sn96.5/Ag3.5 (tin-silver) or Sn63/Pb37 (tin-lead). So you have a flux, No. 71, to make stainless steel soldering possible. You have a stainless steel component and an empty spot on the circuit board.
