This applies to all Orders or just St. Stanislaus?
The more exclusive the order was, the more likely was it (in all its classes) to confer hereditary nobility.
The Russian Wikipedia articles on the different orders give the correspondence between order classes and service ranks.
Order of Saint Andrew the First-called:
1st class - Rank I - III
Order of Saint Catherine:
Not appliccable, as it was for women.
Order of Saint George:
1st class - Rank I - II
2nd class - Rank I - III
3rd class - Rank I - VI
4th class - Rank I - XII
Order of Saint Vladimir:
1st class - Rank I - II
2nd class - Rank I - III
3rd class - Rank I - VI
4th class - Rank V - XI
(Untill 1900 the 4th class also conferred hereditary nobility (Rank IV or VI), but because of complaints about all the merchants and industrialists obtaining hereditary nobility through this channel (receiving the order because of their massive contributions to charity), Nicholas II limited the 4th class to bestowing personal nobility.)
Order of Saint Alexander Nevsky
1st class - Rank I- III
Order of the White Eagle
1st class - Rank I - IV
Order of Saint Anna:
1st class - Rank I - IV
2nd class - Rank V - VIII
3rd class - Rank VIII - X
4th class - Rank X - XII
Order of Saint Slanislaus:
1st class - Rank I - VI
2nd class - Rank VII - X
3rd class - Rank X - XII
We can thus see that as a кавалер (cavalier, knight) of the Order of Saint Vladimir, 3rd class, Chaliapin was styled Ваше благородие, Your Wellbornness.
After 1856 hereditary nobility was bestowed from military service rank VI and civilian service rank IV. All military ranks from XIV bestowed personal nobility, civilian ranks from rank IX. Civilian ranks from XIV to X only bestowed honourable citizenship.
