Wee want make a storage tank for ferrous sulphate and wants to use SS 304 as the tank material. Concentration of ferrous sulphate may differ from time to time. What is the effect of ferrous sulphate on SS 304 as a function of time, concentraion of ferrous sulphate and volume of liquid stored in the tank?

My reference book for recommended pump materials, for pumping ferrous sulfate (aqueous solutions), shows T316 SS as a recommendation, which is an 18-8 molybdenum stainless steel. It also shows Monel and Nickel alloys as being acceptable.
If the tank is going to be welded, you might want to use T316L which is the low carbon grade. Sulfide solutions have a tendency to cause stress corrosion cracking in the welds of the higher carbon grades of stainless steel.
Check this on the internet under "stress corrosion cracking of welded austenitic stainless steels."
