My plastic freight car challenge

This is right, Wayne, because stainless steel has been developed for a wide chemical resistance.
However I do not use stainless steel wire for modelling jobs, my prefered material is nickel silver and phosphor-bronce wire. Both have a good strength and if I should use stainless steel wire I could not bend my everytimes needed shakles for connecting chains to levers or rods. Also bending eyes to rod ends would be many more difficult. Stainless steel is too stiff for many of my work -

Having bent a lot of shackles for model ships, I am still impressed by the perfection of the ones you build!
Stainless steel has its place, and bending miniature shackles isn't one of them! :o
