11 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
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. Other elements in the original table: FeH 39.5 min Al 0.15–0.60 Ti 0.15–0.60; See the limits below for the specific coupled requirements. Footnote H: Fe is calculated as 100 minus the sum of other specified elements; Fe and the other elements must not be treated as unrelated ranges.
