So I'm looking to make a compound setup on my 4bt. For hot piping I'm not sure on what material to use. Im debating on ss304 sch10 or sch40 mild steel. It seems people have used both. I've heard sch40 is way overkill but I've also heard 304 sch10 sometimes cracks do to its thermal properties. So what is your input?? Thanks.
