One thing I don't like is trying to solder steel. So when I found the nuts and bolts supplied for the Garratt locomotive were steel, these were swapped for far superior brass alternatives. I suppose you can make solder stick to steel, car bodywork experts have been doing this for years and calling it "lead loading", but for precision work you either end up using a really nasty flux, or the bit don't stick.
Good job I stocked up on 8BA brass fixings at the last Model Engineering show. I knew they would come in handy one day. If only I could say the same about all the other stuff in my "store".
