Soldering Stainless to Brass


We are trying to bond Stainless Steel tubing to a brass manifold in an application that cannot tolerate corrosion. I've heard that a coating of copper or tin can be applied to the stainless to increase solderability without resorting to an acid core flux. We just need to coat the outside of a thin wall, 3/8 in. o.d. tube for about an inch on each end.

Can this be done at reasonable cost compared to the price of the tubing? Should I try something else?

Yes, Will, you can copper plate the tubes after you have Wood's Nickel plated them. The familiar Revere Ware copper bottomed stainless steel pots can be used as a model of how it would work. Good luck!
