Need to know

In DD What Kind of Spell can Destroy Solid Metal Bars. If there is one what kind of sound does it make

Take a look in the PHB for the hitpoints and hardness of metals, it’s so many hitpoints per inch of thickness I think. I imagine any spell that deals damage will be able to damage materials as well. Not sure if there’s anything to simply destroy objects though.

Metal? In 3e+,the rusting grasp spell should do the trick, i think.
