Hello,

I am looking for any information (techniques or tools) for bending
hypodermic stainless steel tubing. This is fairly thin tubing with the
following characteristics:

Type 316 stainless
2.11mm OD (0.072")
0.0100" wall thickness
ID: 1.6mm

We need to have 90 degree bends, but with a radius that will be safe
enough so the material does not crinkle or rip.

With this information, what tool or techniques are available? I have
heard that one could fit a wire inside the stainless steel tube to
provide support while bending. Or use some melted Delrin to offer
support.

Thanks for any help.

Stainless*) bends *very* good, as long as it is annealed (in an protective
atmosphere).
Cerrobend should do the job. But I'm a fan of mandrel benders.

Here, it is called 1.4203. Good for bending, others are even better.
R = 2.5 D is doable.

Confused the numbers. It is 1.4301
