I have tube bending springs that work well on aluminum & copper. The few times I attempted S.S. did not go that smoothly as the tensile strength is quite different. The way I was able to deal w/ that was to fill the tubing w/ sand before attempting the bend to prevent collapse during the bending process. Take your time. Multiple flexing's works better than "going for it!". You are simultaneously stretching & compressing the metal. A little torch preheating wouldn't hurt.
