cryo treating basics

short version(for the layperson):

long version(for the scholar’s):

There’s a fine line between strength and brittleness. You need some non-plastic deflection to keep the part from shatterring under load. The person doing this needs to be able to analyze the metal and understand the phase diagrams and you need to have a fairly consistent metal/alloy through out the part or else it could make it much weaker.

any questions?
