Based on original SAE J405 JUN1998, Table 1; Mass fraction wt%, note 1: values without a stated range or minimum are maxima; a dash means unspecified and is not entered as zero. Note 5: Cb and Nb denote the same element; Alloying elements must be checked against the corresponding UNS row and additional conditions. Note 4: ordinary carbon analysis is reported to 0.01%, and low-carbon types to 0.001%; This is reporting precision and does not widen composition limits. Type names in original Table 1 may include a common name or a ASTM designation footnote; Search aliases follow only explicit correspondences on the same row; substitution across standards is not assessed automatically. 1998 is the actual composition basis; The specified newer edition has not been verified; equivalence between editions is not assumed. NbTa≥0+8×(C), and ≤1; Check jointly using measured composition from the same heat; independent combinations of element maxima do not establish compliance. Nb+Ta is a combined content; Individual Ta ≤0.10% and individual Co ≤0.20%.

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: (Cb + Ta) 8×C min, 1.00 max Ta 0.10 Co 0.20; See the limits below for the specific coupled requirements.

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.
