Would this even work? Lol

    There are alloys of stainless steel (I forget the numbers off the top of my head, it’s been more than a few years since I worked in that field) that are perfectly fine and compatible for food/grade hot-process work.

      I have these things called cold rocks for my scotch - they’re some kind of stone or earthenware dice-sized cubes that you leave in the freezer. Bought them at an alcohol warehouse shop we have here in Australia called Dan Murphys. They’re great for cooling without diluting.

        I have some of those too. Problem is they’re nowhere near as efficient at cooling as ice cubes are and never cool my drink enough. It’s the melting (phase change) process that does the majority of the cooling with ice cubes, which you miss out on with these solid blocks.

        I forget the exact maths, but a quick googling reckons it takes something like 84kJ to change the temperature of 1kg of liquid water by 20K, but changing the temperature of the same amount of ice from 0K ice to 20K water takes nearly 420kJ, or roughly 5 times more energy, which is why they’re so much better at cooling drinks…

        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.
