humor me, material questions... Say I wanted to make some flanges...header and turbo flanges to start...
what materials would be best...
stainless steel choices..
304L, 321, 347...
Mild steel...
4130 cold rolled or A36 Hot rolled
What thickness would be optimal for sealing for header flanges, as well as turbo flanges...3/8th, or 1/2in
No reason really, I just like knowing stuff like this.
Any and all input appreciated.

you don't want to weld 4130 lol. That **** is very difficult to weld properly, if not done right, the weld will break apart very easily. It requires proper preheat, interpass heat, cool down, and post weld heat treating.

are you thinking about making yourself a set of headers?
Most headers that are made out of mildsteel just use regular mild tubing that I have seen. My fabricator is using regular mild steel tubing, he got from burns stainless.
and the stainless ones I have seen are either 304 or 321 however the welding is a bit different on that. you ahve to have a full MIG setup and the wire is expensive from what Ive herd

Everything you need is at home depot. Go to the plumbing section and you have several choices 1. Cast iron gas pipe. 2.Copper water pipe. 3. Pvc pipe.. I have found that theses dont work too well so i went to the electrical section and nabbed some conduit which works way better then any stainless crap that your looking to use...
For all of you that cant figure this out ITS ALL A JOKE.
