Eurofer-97 is the main structural material targeted for the EU DEMO fusion tokamak and will be exposed to magnetic fields up to (similar to)10 T during operation. It is therefore necessary to understand the effect of magnetic fields on the mechanical properties of the Eurofer-97. We perform 30 uniaxial tensile tests with and without a transverse 1.5 T magnetic field at room temperature. Statistical results reveal that the magnetic field increases the value of proportionality limit by (similar to)2.6% (from 514 +/- 4.5 MPa to 528 +/- 10 MPa), but has minimum ( < 1%) effect on the ultimate tensile strength and elongation of this Eurofer-97. No clear change in the fracture surface is observed.
