Does anyone in SA do Cryo-Treating?

As the title says, wondering if someone local does this, so that I don't have to send parts by some shipping monkey place.

Frozen parts...
Parts are submerged in liquid nitrogen for 24 hours, and improves grain structure of the metal.
It is a continuation of the heat treating process.
