• Cryogenic treatment creates a more uniform “grain”
structure by transforming retained austenite into martensite.
• Modifies the carbon micro-structure through precipitation of
carbides increasing resistance to wear.
• Nitride process diffuses nitrogen into the surface to create a case hardening resulting in superior tool life and exceptional corrosion resistance.
