| Abstract Scope |
9%Ni steel is a material with excellent low-temperature toughness and strength. The steel has excellent weldability as well as stable supply in large quantities, so it is used as a material for storage tanks of LNG. However, 9%Ni steel, as a ferritic steel material, has high soft magnetic properties and reacts very sensitively to the magnetism generated by the current during welding. It causes welding defects and reduces work efficiency. In order to reduce welding defects and improve productivity, basic research on the magnetization characteristics of the sheet materials is urgently needed. In this study, magnetic hysteresis curves and magnetic properties were measured according to the direction and magnitude of the applied magnetic field in a 9%Ni steel sheet specimen. The magnetization characteristics were different depending on the direction of the field, and it was confirmed that this was related to the texture of the steel. |
