Having made a set of strings out of 1" MDF once (which due to an
architects inability to count never got used), I would not use it again
for the strings a staircase with rebates. You are putting it under
stress in its weakest direction, especially when the treads and risers
are well wedged. It would only require a damp atmosphere for a couple
of days and the supporting part of the string would simply de-laminate
from the rest of it.
So pine for the strings works well, MDF for treads, and MDF or ply for
the risers.
Even with kicks and dents?
