To confirm the design and construction process of large superconducting magnet for fusion application, a rules on superconducting magnet structure has been established as part of a code for fusion facilities in JSME standard. The code consists of Quality assurance, Materials, Design, Fabrication and installation, Non-destructive examination, Pressure and leak testing and glossary. This code is the world first documents covering all manufacturing processes conceming the large scale superconducting magnet for fusion. This report deals with "Materials" section in the code. Although the code specifies the materials that will be applicable to the magnet, cryogenic structural materials will be focused and the contents are expounded. A special point described in the code is skipping of mechanical tests at cryogenic temperature. When the chemical composition is satisfied according to the code and when special and additional heat treatment is not performed, the cryogenic mechanical tests are not required. Chemical composition of a welding wire is also listed.
