Abstract
Researchers of Oak Ridge National Laboratory (ORNL) and the US ITER Project Office have developed a cast stainless steel that can be used in the blanket shield modules. ITER, an international research and development project for fusion power, is evaluating this new stainless steel for its possible use in the fusion device. The ITER fusion device uses hot-gas placed in a torus-shaped vessel by using a magnetic field. The new stainless steel shows excellent properties like fracture toughness, impact resistance, weldability, corrosion, and radiation resistance. Researchers used solid solution strengthening and austenite stabilizing elements to develop new grade of cast stainless steel. The new steel also showed good results during stress corrosion cracking (SCC) and irradiation assisted SCC tests. Researchers are now working to improve the material's properties to reduce the amount of machining and welding.
