If I was to manufacture my own manifold to fit a T" turbo what grade stainless is recommended 303, 304 or 316?

321 is the correct grade for turbo manifolds. On 15th May, 2009 TurboDave said:

304 will suffice, but not as robust as 321. 316 - forget it!!!

Does it really matter what grade ???? I was under the impression, the higher grades tend to crack easier ?? It won't matter one iota on a nat-asp motor, but if you ever have your manifold even slightly glowing, then the only stainless that will do the job (again and again) for a turbo setup is 321. I understand 321 to have lower carbon than 304 and is supplemented by titanium to make for the ultimate in high-temp tubing. There is another grade similar to 321 - but don't recall what it is  but 321 is easier to find.
304 will suffice in most cases (so long as it's genuine quality 304 - or even better 304L) however, and is a lot easier to find. 316 will crack and scale after a few serious heat cycles - probably lasting twice, maybe three times longer than plain steel (which isn't very long at all)... Jimsters manifold is made of 321 - and was even Tigged together without back-purging or using solarflux. So far so good! Edited by turbodave16v on 18th Oct, 2006. On 17th Nov, 2014 Tom Fenton said:

Not heard of people using it, the main super material is called Inconel and is used on f1 exhausts. It can easily take red hot temps and apart from being £7000 for a f3 manifold its good stuff!! |
