Cryogenics at Penna Flame

CRYOGENICS

Cryogenic treatment of high carbon tool steel rolls, such as E52100, completes the hardening transformation and assures the complete elimination of retained austenite in the martensitic microstructure. This is performed in a computer controlled chamber by slowly lowering the roll's temperature to -150°F and holding for an appropriate period of time before returning it to ambient temperature. This "super cold" treatment guarantees the roll's dimensional stability for more precise finish tolerances and improved surface wear resistance.

Cryogenics employs cold or ultra-low temperatures to complete the hardening transformation of Retained Austenite to Martensite in some materials and to stabilize others. While "Shallow Cryogenics" is limited to the -120°F range, "Deep Cryogenics" refers to the significantly greater results of temperatures as low as -300°F. At Penna-Flame, you can choose from the full range of 0 to -300°F, with the confidence of computer controls to ensure consistency and to reduce thermal shock effect.
