We present preliminary results on anisotropic flow of particles with strangeness content ( K(0)0s and K+ ) in Au + Au collisions at root s(NN)=2.42GeV measured with HADES. The strange particle flow in heavy-ion collisions is a good probe for the nuclear equation-of-state. Kaon flow was rarely measured at such low centre-of-mass energies, due to the sub-threshold production of strangeness. Thanks to the large statistics of 2.6 billion 40% most central collisions, this study is now possible. The obtained flow parameters (differential measurement of directed and elliptic flow w.r.t. centre-of-mass rapidity and transverse momentum) are compared with previously published world data as well as with flow of non-strange particles.
