I use 300 series stainless on a regular basis with concentrated sulfuric acid at temperatures up to 100F as my tank and cathode with no problems. Now I will agree it is probably not the best choice for an anode basket, but I have never tried stainless for that application personally.Geo said:in my experience, stainless steel is not a good choice for working with a sulfuric cell. concentrated sulfuric acid will attack stainless steel fairly strongly when cold and very aggressively when heated.
Stick with copper.Geo said:i haven't tried stainless over regular kitchen stainless, like bowls and utensils. that's why i said from my experience, someone else might have a different outcome. with that being said, i think I'll try a piece of high grade stainless for my cathode.
