T200 and T350 have forged faces but the body of those irons are cast. Chrome scratches and over time, expect the sweet spot and sole chrome to wear through but that takes quite a few swings. I never have worn the face chrome down as I seem to spread out my contact way too far from the center. :) As for handicap, I never consider it when determining what iron to play. Too many factors contribute to a handicap that really are not related to your irons. Hit what you like and what works for you.

I've got 2023 T200 irons in my bag the now and played the previous gen T200 irons for a couple of years before and i never had any problems with chrome peeling off any of them.
Regards to T200 irons being suitable to your game, who knows.
I'd strongly recommend for you to go get fitted at a Titleist fitting centre!
That way you'll get a properly fitted set of irons to your swing and you'll be able to try the whole range to see what irons are best works / suits you.
Every single persons golf swing, speed, launch, attack angle, loft, lie, grip thickness, longer / shorter shafts, etc is different.
