: [FlyRotary] Stainless 321 Tubing
I'm having a heck of a time finding 321 Stainless mandrel bends in
anything
larger than .049 wall. I'm trying to get 4 - 4" Center Line Radius, 90deg
bends in at least .065" wall. I've tried calling 4 places and researching
a
hundred others online and my last hope appears to be Woolf Aircraft
Products
(http://www.woolfaircraft.com/).
Is .049" wall beefy enough? If I recall, it seems that most people are
using
material that is larger. RacingBeat/MazdaTrix sell .125" wall but only in
"mild steel" not stainless.
Anyone else have any suggestions?

Joe,
I'm using off-the-shelf cones for exhaust parts which are a mixture of 304
and 316 and are usually 1.6mm as a standard.
I know 321 has better resistance to heat and that .049 ( 1.25mm) is fine for
321. I also feel that 1.6 is also fine for 304 and 316.
I would only use mild steel if I expected to change it regularily.
