Iron
Novice and recreational golfers are advised to stay away from 1- and 2-iron. They should even consider replacing 3- and 4-iron with higher lofted fairway woods, 7-wood or 9-wood, because they are easier to hit and produce comparable distance. In general, irons are used for distance that is less than 200 yards from the green.
One of the secrets to successful iron play is knowing exactly how far you can hit with each club. Higher number irons are used as you are closer to the green.

Therefore, cast irons bring significant performance improvement for average golfers who have the tendency to hit the ball off-center.
Forged irons - In contrast to cast irons, forged irons feature a full back on the rear of the club head. Hence, forged irons with smaller sweet spot are less forgiving. But forged irons offer more control and extra 'feel' than cast irons. Therefore, forged irons are recommended for low handicapper.
