Back in the late 70’s I was introduced to the process of Cryo Tempering. Basically, the process in which steels molecular structure is aligned an “”quieted” by submersion into liquid nitrogen. It’s a somewhat more involved process but that’s the simply explanation.
What this process accomplished has made me do it for every firearm platform since.
Again, simply stated, this makes a fire are more accurate over distance right out of the box, recycles wear an tear to all metal mating surfaces, and help by degrees in heat dissipation over multiple shots greatly reducing heat warping of barrel.
As a side note what this process can do for a knife blade or for that matter … disposable razors is nothing short of miraculous.
Cost remains inexpensive and there are a number of place around the country that offer the service. A rifle will cost in the neighborhood of $50, several pistoles about the same. An 5 pounds of knives a such about $45.
Any metal parts gain from this process .. think also of “engine” parts!
Google the process. May not be for everyone but it should be!
Anyone else that’s used this process?
 
Not on guns but my front brake rotors on my car have been cryogenically treated.
I know the NHRA top fuel cars have their engine parts treated.
 
I've never known it to align molecules, but only to remove stress in barrels. Molecular alignment only occurs when the barrel is being manufactured and supposed to be stiffer. I only state this as what I've read on barrel manufacturer's sites. I'm not sure if the barrel is immersed in the liquid or just in the subzero temperature climate?
 
I see your point but I'm with keytone. When I purchase a firearm I only use it the way it was designed to be used and do not exceed the limits. It has already been rigorously tested to perform at that level and that is what I trust it will safely do. So I see no need to further strenghten it YMMV.

As I understand the process it runs about a 72 hour cycle. Liquid nitrogen is the medium. Over the first 24 hours the object is slowly brought down to the lowest temp, about -300°, then held at that temp for 24 hours. It is then slowly brought back to ambient temp over the last 24.
It was described to me as “alining” the molecular structure but may better be determined as “quieting an de stressing” the material at a molecular level.
Not being a materials specialist but only an end user I can only speak to the end product of the process. That product is an impressive improvement of the material that’s been Cryo tempered. The layman’s description I’ve found for DCT is “allows for a significant increase in abrasive wear resistance and durability for many metal-based objects”
Whatever the physics of the process may be the fact that it improves the structure of metal, metal on metal, and metal under extreme stress and/or pressure is the point.
This process, in fact an function, makes an impressive improvement to both function and accuracy of a firearm.
