I am about to start a project and i have a couple of ideas i want to ask if they are any good.
- I am thinking of making the manifold flange out of 409 stainless, its cheaper, has higher strength than 304 at temperatures lower than 500 Celsius, and best of all has half the thermal expansion of the Austenitic grade SS's.
And i have to see how well it does with intergranular corrosion, because 409 has titanium which helps a lot. So its better in all aspects.
- Another idea is using 321 or 347 filler joining the pipes as to avoid hot cracking ? (Bad Idea?)
- One more subject for a turbo manifold is the tube headers thickness, 2mm ? 2,5mm? or more ? Material of tube headers can be 304L or 316L as 321 is a little hard to find..!
