England, steel specs all start with BS followed by a 2-4 digit number.
US SAE are all 4 digit numbers
international UNS numbering system is a letter followed by 5 digits
European Standard for steel is a single letter followed by a number.
however, a google search turns up this:
St3, St30, Stal3 (or Stal30) are different designations of one particular type of steel - 0.30% Carbon content and no additional elements, enhancing the performance. The official GOST (GOsudarstveniy STandard - the Soviet/Russian State Standard) designation of the steel is Stal Marki 30 (Steel Mark 30)
