a For castings of ruling thickness < 28 mm, 0,030 S % is permitted.

b Cr ♦ Mo + Ni + V + Cu < 1,00 %

For each reduction of 0,01 % below the specified maximum carbon content, an increase of 0,04 % manganese above the specified maximum content is permitted up to a maximum of 1,40 %

Niobium: The Nb content shall be between 8 times the C content % present of the alloy and 1 % max

For this steel grade a minimum value of the "pitting index" may be required as Pi = Cr + 3,3 Mo + 16N > 40.
