This paper discusses the tensile results of T91 and 316L with and without irradiation while in contact with liquid lead–bismuth eutectic. The ferritic–martensitic T91 was softened by 50– 100 MPa while the austenitic 316L steel showed a slight decrease in total elongation. Although no irradiation hardening was observed at the elevated irradiation temperature, the ferritic–martensitic T91 steel was prone to a certain extent of liquid metal embrittlement at 200 °C, 350 °C and 450 °C which was not affected by irradiation.
