As a former 3e, current Iron Heroes DM:
The PC looks good! As with IH PCs in general, he's a bit strong at 1st level, but smooths out in power at higher levels. hp, AC, and saves are right on for level.
The only thing I have qualms about are the ability scores. IH uses a much different (tougher) point buy than D&D, and IMHO without ability-boosting items, you should be entitled to the different point system, since otherwise, the ability scores you have will lag somewhat behind your fellow PCs' scores.
One other thing: Ask your DM if he'll allow you to use the IH combat challenge mechanics (specifically the defense challenges). Those are kinda important to the armiger's strategy, so it'd be good to be able to use them.
Nice job in general, though!
