Applicability and limitations
Based on SAE J405 JUN1998 original Table 1; mass fraction wt%. Note 1: a value without a range or lower limit is a maximum; a dash means unspecified, not zero. Note 5: Cb and Nb denote the same element; verify alloying elements against the corresponding UNS row and additional conditions. Note 4: carbon is generally reported to 0.01%, and low-carbon types to 0.001%; this is reporting precision and does not relax composition limits. Original Table 1 type names may include common names or ASTM-naming footnotes; create search aliases only for explicit same-row correspondences, without implying cross-standard equivalence. 1998 is the actual composition basis; the specified newer edition has not been checked, so consistency between editions is not assumed.

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.
