- CRYOGENIC TREATMENT / FREEZING -

After a successful quench and temper, it is frequently desirable to subject the work piece to a cryogenic treatment, also referred to as freezing (or sub-zero freezing). This process induces carbide particles to precipitate into voids in the iron lattice, thus creating a denser, more stabilized structure that reduces friction, wear and thermal softening.

Summary of Benefits:

• Conversion of retained austenite (soft) into martensite (hard)
• Increased strength, toughness, stability and durability
• Increased density of the steel structure
• Lower coefficient of friction
• Decreased residual stresses and brittleness
• Significantly improved abrasive wear resistance
