Abstract (en)

[origin: EP0236805A2] 1. Use of workpieces made of austenitic steel in cryogenics, it being necessary for the workpieces to have a reduced thermal conductivity and at the same time increased strength, provided, however, that the workpieces have been plastically deformed below their martensite transformation temperature.
