Answer 1

I just wanted to add that SG irons (spheriodal graphite) are cast and will give a lot of steels a run for their money – so it’s not a universal fact. Components made traditionally from forged steel – like engine crankshafts – are increasingly commonly replaced with cast SG iron variants since its way cheaper to cast.
