SUMMARY

316L stainless steel (SS) is suitable for use in tanks containing chlorinated water at a concentration of 5ppm. It exhibits superior corrosion resistance compared to 304SS, making it the preferred choice for applications involving exposure to chlorinated environments. While 316L can withstand this concentration, continuous exposure may require consideration of more exotic materials for enhanced durability. The discussion confirms that 316L is commonly utilized in offshore applications due to its robust resistance to corrosive elements.

PREREQUISITES
  • Understanding of stainless steel grades, specifically 304SS and 316L SS
  • Knowledge of corrosion resistance properties in metals
  • Familiarity with chlorination processes and their effects on materials
  • Basic principles of material selection for chemical environments
NEXT STEPS
  • Research the corrosion resistance of 316L SS in chlorinated environments
  • Explore alternative materials for high-corrosion applications, such as exotic alloys
  • Learn about the impact of chlorine concentration on material degradation
  • Investigate best practices for selecting materials in water treatment systems
USEFUL FOR

Engineers, material scientists, and professionals involved in water treatment and tank design will benefit from this discussion, particularly those focused on corrosion resistance and material selection for chlorinated environments.

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
