Stainless Steel

Both steels are quite simple - 304 beeing just primitive. It says: "All austenitic stainless steels are possible."

The manufacturers are very, very, worried about reaction between the MEKP and the pipe or vessel. You need to look at material safety data sheets (MSDS) from knowledgeable chemical suppliers. For example, see "Recommended materials of construction - 304 and 316 stainless, Teflon, Nylon, Kynar and Kel-F"
"Avoid materials such as copper, brass, mild steel, aluminum alloys, natural and synthetic rubbers".
For scary safety info regarding reactivity and need for venting, look at CCOHS:

Thanks to all.
I knew MEKP had positive reactions to quite a few metals and metallic compounds. I had surmised that the relative "inertness" of these two particular items were probable reasoning, but I still needed an answer from "steel" people.
