Performance tube in So-Cal and Columbia Mandrel Bending in Oregon are 2 of the most cost effective suppliers of mild steel and 304 stainless steel mandrel bends, if I'm doing something weird.....Burns Stainless but, sit down when getting quote from Burns. If your doing a lot of stainless, you will want to learn about back purging your welds even Solar Flux wont get the job done, only proper back purging. Burns has some good articles on welding stainless, if you using 316 or 321 I hope your a skilled welder, that stuff isnt fun to weld.
