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.
304 and 316 are considered food safe. 316 is what most industrial food processing machines use.
