You might have reliability problems with a crimp joint to SS.

Or is there a better way to get to the same result? >Cheers.

Plate the SS and solder it. Use special SS solder (and flux).. with caution. Weld the wire to something more solderable.

For a few prototypes, you might try tinning the SS wire with solder and zinc chloride (acid) flux. Clean well then solder the tinned wire to the board with resin or aquious flux. I've had good luck soldering to the SS tabs on rechargable batteries this way.

Who/what says you "need" to solder them?

I strongly suggest you step back and make *very* sure you really have to use steel here, before you consider how to use it.

One typically doesn't want to use steel for much of anything, in electronics. It's not just damn near impossible to solder to copper without killing nearby electronics components and rotting the board in the process --- it's also a rather bad electrical conductor.

If you do have to use steel, I'd suggest you use screw terminals and/or press-on cable shoes instead of soldering.

Yes, unfortunately stainless steel is required for this application. I would avoid it if at all possible.

That is a brilliant idea. Thanks. Its so obvious once you know.

Cheers.

If you use the right flux, then soldering stainless steel is no problem. Look at

for some suitable fluxes.

You will need an acid based flux which will enable you to flow solder around the wire strands. Something we have to do where I work quite a lot. Unfortunately I cannot recall the name on the yellow pot with the red lid but I can look for you tomorrow.
