Thanks for the suggestions on how to improve my brass castings.
In addition to being a metalsmith I am also a licensed steamfitter
and plumber (I like to joke that my midlife crisis was to become a
construction worker). Through this other carrier I have sometimes
have access to stainless piping from which I make casting flasks.
My question is this, does anyone know of a reason not to use
carbon steel pipe for a flask. In my situation carbon steel piping is
much easier to get a hold of as stainless isn’t used on every job. If
you Google ASTM A106 carbon steel pipe you can find the specs on it,
if that helps. I haven’t tried it because I really hate going through
the entire casting process and having it fail, even though I have
done that plenty of times.
Looking forward to your responses.
