It's to prevent sagging and provide reinforcement in the vinyl frame, especially in the sash frames at the meeting rail on double-hung windows.
It's used in a lot of vinyl railing, like for decks and porches, too.

Re: steel in vinyl windows
Both guys are right. Design Pressure increases and sagging correction if you have a really weak extrusion.
Re: steel in vinyl windows
it is an easy way to increase strength in a cheap vinyl extrusion. it is also a way to increase DP ratings for a high quality window. Schuco comes to mind.

Re: steel in vinyl windows
while it is used quite a bit for added strength to vinyl bar. its also used to secure hardware to the vinyl. a lock under pressure would eventually pull loose if it was only screwed into the vinyl...
