S31254
5 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.

Applicability and limitations
Composition alloy: S31254. Table 2, mass fraction wt%; values are maxima except where explicit ranges are given. Ellipses are not replaced with zero. The source actually read is ASME BPVC.II.A-2023 SA814; the cover explicitly states that it is identical to ASTM A814/A814M-15(2019). The analytical method for N is subject to agreement between purchaser and supplier. Product-analysis tolerances under A480/A480M require separate verification and are not incorporated into this table. This standard covers cold-worked welded stainless steel pipe and does not automatically approve a cold-heading product.

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.

Applicability and limitations
Table 1 ladle composition, mass fraction %; a single value without a range or lower limit is a maximum, and unspecified elements are not filled with zero. Cb and Nb are the same element; where both a formula and a fixed limit apply, use the more restrictive limit. This is a plate, sheet and strip standard; suitability for cold-heading wire and actual supply require separate verification. Clause 4.1 also requires applicable provisions of ASTM A480/A480M. This record shows ladle composition from Table 1; it does not mean that A480 or all product acceptance requirements have been fully checked.

Applicability and limitations
Table 1 values are mass percentages; a single value is a maximum, and an ellipsis means unspecified—no zero is inferred. Clause 7.1 requires compliance with Table 1; the general requirements of 5.1 and A999/A999M also apply. This review covers only the chemical-composition table. This is an austenitic stainless-steel pipe standard and does not establish cold-heading wire suitability or full product acceptance. Note C: the nitrogen test method is agreed between buyer and seller.

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.
