We analyse the universal properties of nonequilibrium steady states of driven magnetohydrodynamic (MHD) turbulence in three dimensions ( 3d). We elucidate the dependence of various phenomenologically important dimensionless constants on the symmetries of the two-point correlation functions. We, for the first time, also suggest the intriguing possibility of multiscaling universality class varying continuously with certain dimensionless parameters. The experimental and theoretical implications of our results are discussed.
