Minimum bend radius of Stainless Steel

[weirdo]

I am looking for the minimum bend radius of Stainless 305. Sheet thickness is .008". I want to do ~200 degree bend.

Does anyone have a formula? I was looking in the Machinery Handbook but couldn't find it.

Thanks in advance.

weirdo: I think this is what your looking for
Sheet metal bend allowance:
(.0078T + .0174R) X No of degrees

wierdo,
What do you mean by "~200 degree bend" ? I would think 180 deg would form a hem which would be the most you could bend. Here is a link but not for Stainless but might help.
