High temperature creep and oxidation tests are conducted, since the high temperature strength and oxidation resistance for the ODS ferritic steel are required for its applicability.As a result, It is identified that 9Cr-ODS martensitic steel demonstrated adquate creep strength at 973K, further titanum addition significantly improved the creep strength in 9Cr-ODS martensitic steel, and 9Cr-ODS martensitic and 12Cr-ODS ferritic steels have superior high temperature oxidation resistance compared to PNC-FMS and SUS430.
