304 and 316 are considered food safe. 316 is what most industrial food processing machines use. 304 is somewhat easier to machine, and cheaper, so lots of components are also made from that but it has less corrosion resistance.
Yep those are what I was thinking of; thanks for the cover, internet friend!
Also now I recall we were looking at pressure vessels made of Hastelloy; that was stupid expensive but they had corrosion-resistant properties that were very attractive for that application. And then management bought them and told us to deploy them for a process that was basically a low-temp filtration process. wtf, ok sure, the material is compatible but Hastellonis way overkill. Whatever, it’s your money to burn but damn.
I haven’t machined hastelloy but that’s some expensive shit. That seems like a poor use of that alloy though, but whatever lol as you said it’s their money.
I recently did a reactor that was supposed to be 1200C at 30,00PSI and wanted to use hastelloy X (alloy used in nuclear reactors) for that, but budget made us use 316 at a stupid wall thickness and lower the pressure to 5,000psi @ 800C. Same shit but opposite.
