CRYOGENIC TREATMENT
Cryogenic treatment is widely used process for improving service life and saving on tooling cost. It is a process where the material is cooled to very low temperatures by using liquid nitrogen in which the temperature can go as low as - 196 °C.
WHY CRYOGENIC TREATMENT ?
-
ENHANCES PRECIPITATION OF FINE TERTIARY CARBIDES IN STEELS
-
IMPROVEMENT IN WEAR RESISTANCE
-
INCREASES HARDNESS
-
REDUCE SURFACE ROUGHNESS
-
INCREASE IN FATIGUE LIFE OF THE COMPONENTS
-
BETTER FRACTURE TOUGHNESS CHARACTERISTICS
Cryogenic treatment is a process where materials are cooled to very low temperatures, often below -150°C, to enhance their properties. It improves wear resistance, dimensional stability, and hardness by transforming retained austenite into martensite and refining the microstructure. This treatment is especially beneficial for tool steels, gears, and engine components, increasing their lifespan and performance. It also reduces internal stresses and can enhance corrosion resistance in some alloys. Overall, cryogenic treatment boosts reliability and efficiency in demanding mechanical and thermal environments.
Shallow subzero treatment (SST) – 80 °C
Deep Subzero treatment (DST) -80 to -150 °C
Cryogenic treatment (CT) – 150 to -196 °C
