R&D of ferritic–martensitic steel EP450 ODS for fuel pin claddings of prospective fast reactors

Abstract Present paper performs research results of structure and mechanical properties of the ODS steel on the base of steel EP450 (Fe–13Cr–2Mo–Nb–V–B-0,12C) on all stages of producing: from powders to thin-walled tubes. Also, the results of research on method of sealing thin-walled tubes from steel EP450 ODS by pressurized resistance welding are shown.
