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
The current composition is based on the 1998 original. The specified newer edition has not been checked; equivalence between editions is not assumed.304L · ASTM A493-2009(2013)

Applicability and limitations
The chemical composition currently uses only the verified base-material ranges in the original ASTM A240/A240M—2014; The applicable composition-standard edition and full requirements for A358—2024 have not been verified; compliance with a newer edition cannot be confirmed on this basis. Clause 6.1.1 of A358—2024 references A240/A240M base material; Clause 7.2 specifies separate requirements for welding filler metal; No weld-metal or mixed whole-tube composition is currently provided. Class 1 are welding and radiographic examination classes, not separate chemical-composition grades; This record does not establish capability to supply welded tube; a linked wire-rod product does not establish direct supply of A358 welded tube. Table 1 gives heat-analysis mass percentages; A single value without a stated range or minimum is a maximum; unspecified elements are not entered as zero. Cb and Nb are the same element; Where both a formula and a fixed limit apply, the stricter limit is used. 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 the applicable provisions of ASTM A480/A480M; This record displays the heat composition in Table 1; it does not establish verification of A480 or all product acceptance requirements.

| C | 0.02 ～ 0.02 |
| Cr | 19 ～ 19 |
| Mn | 1 ～ 1 |
| Ni | 10 ～ 10 |
| Si | 0.4 ～ 0.4 |
Applicability and limitations
A match in the materials database does not establish suitability for cold heading or guarantee finished-product strength. Confirmation must consider wire condition, deformation, heat treatment and tests on actual parts.
