Using an eighth-order Taylor expansion in baryon chemical potential, werecently obtained the (2+1)-flavor QCD equation of state (EoS) at non-zeroconserved charge chemical potentials from the lattice. We focused onstrangeness-neutral, isospin-symmetric QCD matter, which closely resembles thesituation encountered in heavy-ion collision experiments. Using this EoS, wepresent here results on various QCD material parameters; in particular wecompute the specific heat, speed of sound, and compressibility alongappropriate lines of constant physics. We show that in the entire rangerelevant for the beam energy scan at RHIC, the specific heat, speed of sound,and compressibility show no indication for an approach to critical behaviorthat one would expect close to a possibly existing critical endpoint.
