Masoud, Are your temperatures in C or F ? There is much information, including published research papers and reports, available on the internet regarding caustic soda (NaOH) systems. Based on the conditions you describe, 316 SS should be acceptable.....according to the document noted below, 316SS is acceptable for up to 50% solution and 70 C http://www.corrosionsource.com/technicallibrary/nidi/literature/pdf/10019.pdf Based on Table #2 of the NIDI Report, Alloy 600 and alloy 400 should provide acceptable setvice for 50% solutions to 125C Hope that this helps..... How big is the heat exchanger ? MJC
