For strain rate sensitive material (e.g., steel), often the Johnson Cook (JC) model is used, in explicit dynamics - see the help manual on that.
(Not sure how to use/convert your data into the JC parameters needed in Ansys - perhaps if you look on the internet or if someone else knows)
Also this is of help:
