Based on your question, I assume that this is the first time that you have designed such a facility and that the budget imposed by your MBA masters does not allow for inclusion of a metallurgist or to to perform the necessary corrosion studies on a contracted basis ...

It is far better to pay the money to make the right choice early than to trust a group of aging hostile engineering strangers on the internet.

I strongly believe that plain Carbon steel will be just fine for this acidic salt service (for a short time).... But, then again, I have just gotten out of the hospital and am still taking some powerful psychoactive drugs.

You may have found yourself in the magical engineering place called "SCR*WED" where your 60C temperature eliminates glass lined components, your dilute HCl eliminates your austenitic SS choice and your abrasive salts eliminate most other options ....

So .... I would take the third-world approach and make everything out of carbon steel and count on replacements on an annual basis ... (Wait, I have to go take my pills..)
