321 stainless steel welding procedure

  • Why You Shouldn't Weld Carbon and Stainless Steel Wire ...

    A while ago, Marlin Steel's engineering team was asked by a client whether a stainless steel nut could be welded to a carbon steel wire form.. The short answer was "yes, you can, but you probably wouldn't want to." In most cases, if you need a corrosion-resistant wire form, it's best to go all the way with stainless steel wire rather than mixing and matching metals.
