9 source records. Standards, editions and conditions are presented separately; matching grade names do not establish interchangeability.
Refer to each source for mass fractions and analysis type. Missing values are not treated as 0. Manufacturer typical values, standard guarantees and measured heat results must remain separate. Use the material selector for calculations and condition selection.

printed page 11, row 18; Manufacturer composition table (%), covering billets and bars; analysis type not stated. The official-website filename includes 2024; no edition number is shown inside the document; Not treated as a verified edition of the corresponding standard or a supply guarantee from Creation Group. Condition: Nb+Ta=0.15-0.45; Only the combined total is coupled; missing independent element limits are not inferred
Composition conditions
- The original table lists Chemical Composition (%); Heat or product analysis is not identified; the values cannot be treated as guaranteed limits under the corresponding standard.
- The correspondence column gives designation mappings in manufacturer information; No standard year is given, so this is not upgraded to a verified ASTM/GB/JIS/EN/RCC-M standard record.
- Different S, Ni and Ti/Nb conditions for the same grade designation are retained as separate original rows; dashes are not entered as zero.
- Nb+Ta=0.15-0.45; Only the combined total is coupled; missing independent element limits are not inferred
