309S

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.

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.

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.
