Thermal stabilisation of MgB 2 demands for a multifilamentary structure the filaments being small in diameter and the homogeneous MgB 2 phase fine grained. Reactions with the sheath have to be avoided widely. Taking this into account we developed very thin steel reinforced MgB 2 wires for an application in a research satellite. The in-situ phase formation in the wire from Mg+B powders was chosen as most favourable method to achieve a good grain connection and thus high transport currents. We report on transport current measurements and the mechanical performance with applied tensile and bending strains. With standard undoped in-situ MgB 2 wires an improved processing route was developed applying a low temperature annealing which gave improved critical current densities of 38 kAcm -2 at 6 T and 10 kAcm -2 at 8 T, 4.2 K.
