NOTE:  All non-special material helmets have the same number of enchantment points regardless of design (there are about 5 or 6 different styles) or protection provided (+1, +3, +4). Once you reach +5 or better, the helmets have the same EP's as the helmets which are obviously made of special materials. Some +4 helmets will be made of silver, but unless you have taken silver as a forbidden material, you will not be able to tell the difference.  Silver armor is extremely rare.  Unless you have extraordinary patience or luck, you will probably not find a single piece (helmets excepted).  Try as I might, I have not been able to acquire a silver Greaves, so I do not know what the EP of this items is.

There seems to be a discrepancy in the numbers I get for Cuirasses.  I first noticed this with an embossed, skirted Ebony Cuirass that came out at 1400 EP's while a simple Ebony breastplate came out at 800.  I have not checked to see if this holds true across materials, but I would not be surprised if fancier cuirasses had more EP's than plain ones.

The pluses which go with the various materials do not add up to the armor class shown on the inventory screen.  As best I can make out, you receive +1 to your armor class for wearing armor plus twice the armor bonus for the material. Thus, a leather cuirass would provide +1 for wearing armor plus +2 for the material of the armor, giving you an armor class of 3 in the area protected by your cuirass.  By the same token, a daedric cuirass would provide +1 for wearing armor and +20 for the material, giving you an armor class of 21.
