Discussion Overview

The discussion centers around the suitability of 316L stainless steel (SS) for use in a tank containing chlorinated water at a concentration of 5ppm. Participants explore material properties and corrosion resistance, comparing 304SS and 316L SS, and consider alternatives.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant inquires about the suitability of 304SS versus 316L SS for chlorinated water, noting that 316 is generally considered more corrosion resistant but lacks specific measurements.
  • Another participant mentions that bronze components are commonly used in water service pumps, suggesting that while 316L SS should be fine, there are other material considerations.
  • A different participant asserts that 316 is highly resistant and commonly used in offshore applications, implying it is one of the best regular stainless steels available.
  • A later reply indicates that 5ppm is the maximum concentration that 316L can withstand under constant exposure, suggesting a limit to its suitability.

Areas of Agreement / Disagreement

Participants generally agree that 316L SS is likely suitable for the application, but there are varying opinions on its limits and the potential need for alternative materials under certain conditions.

Contextual Notes

There are limitations regarding specific measurements of corrosion resistance for both 304SS and 316L SS in chlorinated environments, as well as the potential need for more exotic materials if 316L is deemed insufficient.

Hey all, I'm looking to find information on material to use for a tank containing chlorinated water at 5ppm concentration. I was wondering if 304SS or 316L SS would be suitable or if we would have to use some other form of Stainless Steel. All that I have read shows 316 as being more corrosion resistance but does not give any specific measurements.

Thanks

I know that on a lot of the water service pumps we see at my job, we usually use bronze impellers, bushings, etc., so that is one consideration. But as far as I can tell, yes, 316 should be fine.
 
We use 316 for offshore (seawater) stuff, it's about the most resistant regular stainless steel.
If this isn't good enough you have to get pretty exotic
 
Thanks for all of the replies, after looking on the internet a bit more it looks like 5ppm is the max that 316L is withstand constant exposure to.

Thanks Again
