Hello all. I am going to build my own forging studio and I have a
question about home built gas burners.

I have a copy of Michael Porter's book Gas Burners for Forges,
Furnaces & Kilns. All the burner designs in this book call out #316
stainless for the nozzle. I have not had any luck finding #316
stainless pipe in my area and I am wondering if #304 stainless pipe is
an acceptable substitute. Anyone have any experience in this area?

A forging studio? Never heard it called that before.

A mighty good book that. I actually live in Oz, so an American book (no
matter how good) usually requires a lot of research to get local product
names, that is if there is an equivalent product.

I used the Mike Porter book as a guide, and developed my own simple
burners, that work just as well, but only require a little machining and
a little silver soldering. By the by, I too needed a flare for my
simple burners, and gave up using the suggested products in the books
and American sites.

I simply went to a local steel merchant and asked for stainless steel
pipe that would tolerate a lot of heat. I ended up with a type of
exhaust pipe that does the trick. Have no idea the name of the steel
and don't really care... it works.

My point is ring around the steel merchants local to you and ask, they
usually know what to sell you.

316 (or to be more exact 316L) is a common stainless used around boats
because of its good anti corrosion properties. There is little, or no,
reason to use it for a burner tip as since the tip is going to get hot
every time you use it is going to corrode. Go ahead with the 304, for
your use it won't make any difference.

Flares have to be replaced, just choose a suitable material and you wont
have to replace it as often.

The only experience I have with them is the one I made for myself, so
the rest is passing along what I've heard second-hand.

The main thing here is that if you're making a venturi burner, they
have a reputation for being really touchy to build and keep running-
though there is the obvious benefit of not requiring a power source to
run a blower. That part is second-hand- I don't really know if the
reputation is deserved or not.

But, if you decide to go with a forced-air blower, they are dead easy
to build. Rather than trying to track down stainless pipe to make a
flare, you can just use black pipe off the shelf at the hardware
store, and get to work. There are plenty of plans floating all over
for these, and it makes the question of 316/304 stainless moot.

I wish I could tell you what the difference is, and we actually use
both at work, but all I know about 316 is that it costs more. We
don't get it in pipe, or I'd send you a piece- though if you have a
slip roll or some other method of bending it into a cone, I could
probably hook you up with a little piece of scrap all ready to roll
into a cone. IIRC, I have 14ga 316 sitting in the rack, but we don't
use it very often at all.
