S40500
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.

| Ni | ≤ 0.6 (lower limit not stated) |
| Al | 0.1 ～ 0.3 |
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.
Verification notes
Corresponding UNS rows and table notes in the 1998 original have been checked; this does not verify a newer edition.S40500 · ASTM A240/A240M-2014

Applicability and limitations
Table 1: heat-analysis composition, mass fraction %. A single value without a stated range or lower bound is a maximum; unspecified elements are not assigned zero. Cb and Nb refer to the same element. Where a formula and fixed limits both apply, use the stricter limit. This is a plate, sheet and strip standard; cold-heading wire applications and actual supply require separate verification. Clause 4.1 also requires compliance with applicable provisions of ASTM A480/A480M. This record displays heat composition from Table 1; it does not establish complete verification of A480 or all product-acceptance requirements. Other elements as printed: Al 0.10–0.30; see the constraints below for the specific coupled requirements.
