Now that's some seriously COLD STEEL! :)
As for me Stretch2 VG-10 in the left pocket and Stretch1 VG-10 in the right pocket.
About -300° F. I dipped it into a cupful of liquid oxygen.
It was a late night at work. :rolleyes:
Liquid Oxygen wow what kind of job involves working around stuff like that? must be (groaning) :p COOL!

I’m curious too. We have an SEM at work that uses liquid nitrogen for cooling the machine.
It is cool.
We have a 6000 watt CNC Laser cutting machine here at work. We use oxygen as an assist gas when cutting through thick steel (from 3/16" all the way to 1" thick mild steel). The oxygen helps burn away the steel as the machine cuts.
The laser uses oxygen gas not liquid, but we get tanks of liquid and then pull off the gas as it evaporates. And if the laser pulls enough off fast enough (such as when cutting lots of 3/4 or 1" thick steel) the seals around the liquid valve shrink enough to allow some liquid to dribble out. Just hold up a styrofoam cup and you can get a cupful in a few minutes. :) It's pale blue in liquid form and about -300° F.
We use liquid nitrogen for cutting aluminum and stainless steel, and mild steel 10ga and thinner, but we have a giant bulk tank for that and I've never played around with it.
