Oxide dispersion strengthened (ODS) steels with nano-scaled oxide particles in high density in ferrite/ martensite matrix and on grain boundaries of ultra-fine grains have excellent properties as structural material for fusion blankets, while some issues of fabrication processes are still remaining to be solved. In this overview, material properties of recently developed ODS steels are introduced in comparison to ferritic/martensitic (F/M) steels: 1) mechanical properties, 2) corrosion behavior and 3) radiation tolerance in ODS steels, which are outstandingly superior to the F/M steels. Coupling use of the ODS and F/M steels is effective to expand the design margin of fusion blankets. R&D of dissimilar joining of FM/ODS steels is indispensable.
