Corrosionpedia explains Copper Sulfate

Copper sulfate is a key chemical ingredient used to perform corrosion tests and confirmations on surfaces that have been previously treated to ensure preventative accuracy and sustenance. One such test is an inter-granular corrosion test designed to ensure a corrosion-free surface for stainless steels. A stainless steel sample is boiled in a copper sulfate solution for twenty four (24) hours, after which it is examined for inter-granular irregularities.
