corrosion from bismuth on stainless?

[arto]

Has anyone ever run into corrosion troubles from using low melting temp Bismuth Alloys to bend 316L tubing?

I've seen it use hundreds of times on 304, 316, and 321 SS tubing with no problems.

The only problem I've heard of with these alloys is getting them too hot.
