Your examples don't look all that grainy to me. 3200 in the Filmworld means grain and higher temperatures usually means even more grain. Try to develop the film at a lower temperature say 20°C or even 19°C instead of 23°C. Use X-Tol @ stock dilution 1+1 gives slightly sharper results but more grain.
The development time seems a little long to me as X-tol Stock only requires 7.5mins @ 20°C.
Good luck

In my experience, Delta 3200 grain looks a lot grainier when scanned than when you do a print. The scanning process seems to not capture how smooth a print on Ilford fiber paper can look with this film.
