Eurofer 97 is the main structural material targeted for the DEMO reactors which will be operated under magnetic fields. It is therefore imperative to understand the effect of magnetic fields on the mechanical properties of the Eurofer 97. Here we preform 30 uniaxial tensile tests with and without a 1.5 T magnetic field at room temperature. The statistical results reveal that the magnetic field has minimum effect on the ultimate tensile strength and elongation of this Eurofer 97. No change in the fracture surface is observed. The importance of perform fatigue and creep tests under a magnetic field is discussed.
