Probably the reason the big toolmakers are don’t use cryo is because they are in the business of selling tools. Why would they be interested in selling fewer tools? It is more the end user’s that are interested in the process for the reason of saving money. One end-user speaks quite highly of cryo treatment of tools. They are called the Ford Motor Company, ever hear of them? In fact they wrote an article about how they have their parts cryo treated. The article was published in Fords own magazine "“Tool & Die Troubleshooter†Vol. 1, Number 4, summer 1995. You may also want to check out some of the following articles written by people who are not in the business of selling cryo. The first article actually touches on a subject that they describe as “thermal shockâ€.Cryogenics goes deeper by Paul Cohen Ph. D.
