For the operating conditions specified in the title, which is better: carbon steel or 316L? By how much is the resistance to alkali embrittlement of 316L better than that of carbon steel? Thank you!
Consider using lined pipes, carbon steel + PTFE

Hello! In our company, 32% of the caustic solution passes through the high-temperature section before the cooler in the ion exchange cell, where the temperature is ≥45°C; for this section, N6 material is used for the pipes, while 316L material is used for the pipes and fittings after cooling.
Carbon steel lined with F4 is better, offering a longer service life
What kind of stainless steel is 310? Is it okay? I see that on some design drawings, the value under this operating condition is 310.
