In the Composites industry, Methyl Ethyl Ketone Peroxide (MEKP) is widely
used as a catalyst for many resin system and processes. It's manufacturers
require any piping for the transport of, or working vessels for the use of
MEKP, to be made of either 304 or 316 Stainless Steel.
No one here could give me a definitive answer (mostly all composite nerds)
as to why these two exclusively are specified. Being an old "heat treater"
myself, and having been thrust into the composite world only a short time
ago, the steel man still in me needs a better answer.
