hello everybody, is it possible to solder steel?
Steel is fairly easy to solder on, even most grades of stainless.
You can get a special "black" paste flux from Rio Grande, but I have
success using Handy Paste Flux, that thick, white, gritty stuff. If
the steel get's black from heating, the solder won't stick and you
have to physically abraid away the discoloration. Don't put it in
your regular pickle or all your silver and gold articles will come
out with a light coating of copper. Silver braize (silver solder,
sheet or wire) works fine, so do the gold solders.
