   Why does a steel ball appear hotter than a charcoal piece at the same temperature when picked up by bare hands?

   That has nothing to do with the thermal radiatiuon.
   Metals are actually worse at radiating heat.
   As long as you can touch objects, without burning yourself, conduction is the dominant heat transfer process.
   The metal just has a higher thermal conductivity so it "deposits" more heat into your hand in a given amount of time.
   That is why it feels hotter.
   Your skin gets warmed faster.
