Abstract
The high ductility and toughness at liquid-helium temperature makes nitrogen-stabilized austenitic steel a very attractive structural material for cryogenic applications. It is widely used as structural material of the casings of large coil magnets and also in Nb3Sn superconducting cables as a reinforcement material to ensure high mechanical stability. The reinforcing austenitic steel content in superconducting Nb3Sn-coil is three times that of Nb3Sn and bronze together.1 In addition to good mechanical properties at liquid helium temperature, the steel must have the following properties: 1) nonmagnetism, 2) microstructural stability with respect to deformation temperature, and 3) small thermal expansion coefficient.
