Design considerations in the use of stainless steel for vacuum and cryogenic equipment / Geyari, C
The properties making austenitic stainless steel a preferred material for the construction of high vacuum equipment are reviewed. Best results are obtained if attention is paid to the improvement of welding properties, particularly with a view to prevent intercrystalline disintegration. [...]

Preparation Femtosecond Laser Prevention for the Cold-Worked Stress Corrosion Crackings on Reactor Grade Low Carbon Stainless Steel / John Minehara, Eisuke ; Nisimura, Akihiko
We report here that the femtosecond lasers like low average power Ti:Sapphire lasers, the JAERI high average power free-electron laser and others could peel off and remove two stress corrosion cracking (SCC) origins of the cold-worked and the cracking susceptible material, and residual tensile stress in hardened and stretched surface of low-carbon stainless steel cubic samples for nuclear reactor internals as a proof of principle experiment except for the third origin of corrosive environment. Because a 143 °C and 43% MgCl2 hot solution SCC test was performed for the samples to simulate the cold-worked SCC phenomena of the internals to show no crack at the laser-peered off strip on the cold-worked side and ten-thousands of cracks at the non-peeled off on the same side, it has been successfully demonstrated that the femtosecond lasers could clearly remove the two SCC origins and could resultantly prevent the cold-worked SCC..

Friction stir welding of AISI 316LN high strength austenitic stainless steel for cryogenic application / Aviles Santillana, I (CERN) ; Debeux, J (CERN) ; Meyer, M (CERN) ; Muddamallappa, M (Texas A-M) ; Polo Picazo, A (CERN) ; Robe, H (Unlisted, FR) ; Rodriguez Castro, E (CERN ; Madrid U.) ; Sgobba, S (CERN) ; Weiss, KP (KIT, Karlsruhe)
Friction stir welding (FSW) is a solid state joining process that uses the heat generated by the friction of a rotating tool and the base material to join materials together. Due to the fact that the material is never melted, and that extensive plastic deformation is introduced in the weld seam, a unique set of properties is achieved. [...]

Secondary Phases Quantification and Fracture Toughness at Cryogenic Temperature of Austenitic Stainless Steel Welds for High-Field Superconducting Magnets / Santillana, Ignacio Aviles (CERN) ; Pison, Pilar Fernandez (CERN) ; Langeslag, Stefanie Agnes Elisabeth (CERN) ; Sgobba, Stefano (CERN) ; Lunt, Alexander (CERN) ; Boyer, Christelle (Euratom, St. Paul Lez Durance) ; Navas, Elisa Maria Ruiz (Carlos III U., Madrid)
The ITER magnet system is based on the “cable-in-conduit” conductor concept, which consists of various types of stainless steel jackets filled with superconducting strands. The jackets provide high strength and fracture toughness to counteract the high stress imposed by, amongst others, electromagnetic loads at cryogenic temperature. [...]
