Where did you get the steel sprocket and how much, it might be a job for this coming winter lay up.
Factory and lots...but not a vast amount amount more than the aluminium sprockets so well worth a try. Will need good cleaning and protection to avoid rust during any extended period of non-use I reckon once the coating wears off. The steel sprockets should be generally available any day now; they were waiting on a fair sized batch to arrive when I called by last week.
