- Cryo process: creates a more uniform grain by transforming retained austenite into martensite, thus reducing brittleness; less likely to break and better tensile strength
- Nitride process: liquid nitrogen diffuses nitrides into the surface to create a case hardened surface resulting in superior tool life; creates a surface hardness to 70 Rockwell C; allows heat to dissipate quickly
