Does anyone know how to identify stainless steel?
I think the exhaust on my car may be stainless - but only because it's not rusted and still has a silvery appearance. It's made by Walker.
(I'd read that magnets won't stick to stainless but a test on kitchen cutlery proved that not to be the case!)
Also, can a stainless exhaust be welded? (I noticed there seems to be tiny blow from seam.)

Try the magnet, stainless can have different compositions in its make up.

Re: How to identify a stainless steel exhaust
The problem that you have is that most stainless exhausts are made of 304 stainless which is easily magnetised. It is usual to tig weld a stainless exhaust, I use a grade 309 filler rod, the main problem is cleaning prior to welding.

Warranty?
How small and where? Can be a fix - or a warning of greater imminent failure.
An easy (temporary?) fix for a pin hole might be a jubilee clip with exhaust putty. I’ve fixed larger holes, before now, with a metal patch clamped on with a jubilee clip or two.

I have successfully welded stainless tube with a MIG using stainless wire and I am a very novice welder.

Re: How to identify a stainless steel exhaust
Thanks guys
It looks to be a very small leak in the joint where the pipe enters the silencer - there's no noise but I happened to notice a few millimetres of black discolouration where it's been blowing, when I was greasing my trunions.
The exhaust has been on the car for some 25 years, so I can't complain!
It would be an easy weld but I don't have Tig (or Mig!) yet so I might look out for another silencer as a standby.

Liquid metal putty would fix it
