So I'm building some equipment for my distillery and I've always used 304 and 316, of course, but thought I'd save the headache and use 303 SS for some filling machines parts. Now Ethanol will be in direct contact with the parts. So I'm just wondering will it be safe for the alcohol to touch it, meaning will it leach anything out from the metal? I only ask as you never see mention of 303 SS in these sort of parts, usually it's always 304 and 316. Now mostlyfor their ability to withstand corrosion.

Any suggestions would be helpful.
