No.

It is stated here: "... as hard as the steel of the Dwarves, but so malleable that he could make it thin ...". So, despite the higher toughness (implied with 'hardness'), it was applied in thinner sheets, which prefectly justifties the current lower overall protection value imo. Thinner plates absorb less impact energy, hence have lower protective value.
