321H

2 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.

Carbon-equivalent reference

Estimate from manufacturer-published ranges, not a standard guarantee or measured heat result; formula applicability requires review against the application and process.

Applicability and limitations

Walsin Lihwa official catalogue, PDF physical page 7

printed page 10, row 28; manufacturer's composition table, %, covering billets and bars. Analysis type is not stated. The official filename contains 2024, but no revision number was found inside; this is neither a verified edition of the cross-referenced standards nor a supply guarantee by our company. Condition: Ti=4*C-0.6; the minimum is coupled and the formula is not converted into a fixed numerical value.

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.
Ti=4*C-0.6; the lower bound is coupled and the formula is not converted into a fixed value.

Verification notes

Composition, conditional rows and linked requirements checked cell by cell against the original image; anomalous row 303 on page 10 excluded.
