Mmm, cryo treatment of nickle silver defies all logic to me, not saying it does not work as I really not up to date on cryo treating, but nothing in the mix can harden vee temperature variations.
I was taught mettalurgy as part of an apprenticeship i did in my younger years, nickle silve is typically copper, zinc and nickle, this composition only gets harder through cold working, we use heat to soften it again.
If a customer wants hard nickle silver you can roll it and then unroll it and roll it again a few times, this will dramatically increase the hardness
