Hi Meredith,

       I would expect ordinary steel to work for a time, but dry rubbing 
ordinary steel to steel contacts tend to produce a small pile of rust after a 
while. 
       You might consider putting a drop of clock or similar protective oil 
on the hinge and a paper dust screen around it?

       Regards,

       Chris
