 a. Molybdenum not intentionally added.
 b. CF-3A, CF-3MA, and CF-8A have the same composition ranges as CF-3, CF-3M, and CF-8 respectively, but have balanced compositions
 so that ferrite contents are at levels that permit hogher mechanical property specifications than those for related grades. They are covered by
 ASTM A 351.
 c. Nb, 8 x C% min (1.0% max); or Nb + Ta x %C (1.1 % max).
 d. Similar wrought designations are listed only as a guide for comparison to cast grades; they are not equivalent.
 e. Although manganese, sulphur and phospohorus contents are not listed in this table due to limited space, they are specified; see
 appropriate ASTM standard for more details.
 Single values are maximum, unless otherwise specified.
