How many milligrams per liter of sulfate ions can 316L stainless steel withstand?
The temperature doesn’t need to be high; a concentration of over 80% is sufficient
The conditions for the poster’s request are incomplete. It’s hard to answer this question. Temperature is the most important factor.
Consider the temperature and whether the medium contains chloride ions
The original poster didn’t ask clearly, so I can only provide a picture from the past of HaiChuan as an answer; as for how to use it, the poster will have to figure that out by looking at the picture themselves.
To all my students*. Thank you for sharing your experience and information.
The corrosivity of sulfite formed by sulfate ions is not strong; it mainly depends on temperature, pH value, and the levels of other impurities.
