Greetings,
I found a place that sells SS fittings for a great price and it is only a few miles away from my new home. www.buyfittingsonline.com . They have 304 and 316 fittings. The 316 are slightly more expensive. Can anyone tell me the difference between these alloys regarding brewing chemistry? Is there any difference for out applications?

Thanks,
Peter Roman

Both 304 and 316 stainless alloys work fine for brewing applications. You may use them interchangeably. The 316 has a slightly higher resistance to corrosion, but this is unimportant in brweing.

So, it looks like you can use bleach on 316, but not 304. Not that I would, but they say it resists hypochlorites. Nice.

Joseph -

In my previous life as a boiler technical consultant, we use to urge our customers not to expose the stainless superheater (steam cooled surface) sections to any type of cloride contamination. A minimal amount of clorides even from potable water was enough to cause major problems in the stainless. Here's the BIG difference though: this stainless (304, 316 and other more exotic grades) "operated" at 3800 psig and 1000 degrees F.

I wouldn't worry about using bleach on SS at ambient conditions though I would probably try to avoid extremely long contact times.
