Is Cryo Really Neccesary?

But Bohler-Uddeholm guy at Blade told me that with their more complex alloys like Elmax and 390, dry ice doesn't get quite cold enough for complete transformation. it misses that "nose" by about 15-20 degrees.

Will, that is an interesting idea of how to get LN at a reasonable cost. Sandvik maintains there is NO benefit to LN on their steels. That -95ºF is just fine, and even a -5ºF freeze treatment is of benefit.

Good info! thanks

Learn to read the spec. sheets and the time/temp. charts. They will tell you all you need to know. It really is that simple.
