Where I work, we've got alloys that are super freakin' hard. I had to analyze some samples and the metal needed to be cut into tiny pieces so it would dissolve in acid. It took me a week using a diamond wheel saw to cut the stuff up and then several more days to dissolve the stuff. We ended up using some hydrofluoric acid to finish the job.

316L stainless by contrast is a walk in the park. And 316L makes mild steel look like butter.

904 is harder due to some extra molybdenum and copper added to the mix. A pain to machine but its a lot more resistant to salt water corrosion.

^^^Cool!! Would love to see videos of that type of work.

What is the purpose of dissolving those steels? Color me intrigued.

We can analyze an alloy to determine its composition. How much nickel, copper, silicon, molybdenum, vanadium, chromium, etc. is in the alloy. That's to make sure it really is the alloy it is supposed to be.

The machine shop has a wire edm machine that cuts metal like a hot knife through butter.

And you might as well see some friction stir welding

Had no idea such machines/processes even existed.

Took.me down a tree rabbit trail of videos and info on alloys. Fun!
