Actually, hot bending does NOT work harden stainless steel. That is what happens when you bend it cold.
Bending austenitic stainless steel and keeping full strength is a very fussy project. Temperature for bending and temperature for re-annealing the metal are different and not likely to be well done by someone inexperienced on a large piece.
Done “at home” it is very likely that BOTH hot and cold bending will reduce the ultimate tensile strength. If you bend it cold do as Bill R suggests, in a press, quickly and all in one go to reduce further work hardening that already is present from the initial bend.
And Capt Richard is right: there aren’t very many properties of stainless that make it a better material to make an anchor out of compared to good galvanized carbon steel—but it IS pretty!

Bill you're right about heating stainless steel. It work hardens the stainless and leaves it brittle. And don't hammer it either does the same thing. Also keep in mind that pound for pound steel anchors are by far stronger than SS.

About 10 years ago, I also bent the Wasi stainless steel anchor shank. I also contacted Wasi and was told to straighten the shank using a "cold" press, no heat. I was told that heat will weaken the stainless steel.
I am not saying who is right here, but I firmly believe that heating that shank will weaken the strength of the shank.
