CRYOGENICS
How does cryogenic processing improve hardness?
​
Hardness is improved in metals subjected to a cryogenic treatment process when retained austenite is eliminated from the molecular structure and compared to a conventionally heat treated metal workpiece.
​
How does cryogenic processing improve toughness?
​
Low temperature conditioning of martensite is responsible for increasing the toughness of metal parts when compared to a conventionally heat treated metal workpiece. A deep cryogenically treated component shows far higher toughness than conventionally heat treated material, or the raw metal material.
