Development of a High-Strength High-Manganese Stainless Steel for Cryogenic Use
Superconducting magnets are now being put to practical use in scientific and industrial fields. Toroidal coil of nuclear fusion reactor is an example of application of SCM. In this case, the structural material of SCM is required to possess high-strength, high toughness, and good fatigue behaviours. This material is also requested to keep metallic lustre or to be stainless so as to maintain high vacuum because its surface is exposed to vacuum for thermal insulation. JAERI has proposed the characteristics necessary for this material, which are listed in Table 1.
