I need to make a bracket and weld it to an exhaust system made from 409 stainless. 409 seems to be hard to come by, and I am needing to get this project done.

Is there an alternative common stainless that can be used? C

I thought about using a 300 series and brazing it on with silicon-bronze rod, but this is going to be a hanging support, so strength is a concern.

Any help is greatly appreciated.

I'd use 309 stainless wire and mild steel for the bracket.

I'd use 309 stainless wire and mild steel for the bracket.

309 will work fine as a filler and be the safest, but 304 can be used without problem for the bracket/hanger.

409 can be welded quite well to 304 and 316. I have used plain 316iL filler in the past to weld 409 pipe to a 304 flange and never saw any issues.

I tend to use 304/316 hangers as I hate the crusting-and-crumbling that immediatly starts happening on mild steel exhaust parts

Bye, Arno.

Yep, that works well too.
