It can take quite a lot.... The last time I saw one of his armour's severely damaged was when the Sentient Armour ripped apart the much older Modular Armour.
The Retro Armour (the first version of the suit that eventually became the Sentient Armour) was almost destroyed fighting Count Nefaria.... which is understandable as the guy seems to have strength and durability at a level beyond Superman type characters.
Apart from those instances I don't recall many instances where his armour has taken extremely heavy damage.... and he's fought most of the heavy hitter on Marvel Earth.

That may have been the S.K.I.N. armour.... it had a prototype metallic alloy covering that was supposedly only a short step down from adamantium

"To his basic erector set of helmet, chestplate, gauntlets, and body suit, Stark added a full body armor crafted from the revolutionary substance. Capable of shape-shifting into a nearly adamantium-hard shell, SKIN withstands lasers without a scratch and is strong enough to shatter omnium steel bars without a dent."
The company that created SKIN was destroyed a few issues later... which is why he no longer uses it
