Applicability and limitations
Table 1, mass percent; A single value is a maximum; ellipses mean unspecified and are not entered as zero. ; Clause 7.1 requires compliance with Table 1; The general A999/A999M requirements in Clause 5.1 still apply; only the chemical-composition table was checked in this batch. ; Austenitic steel pipe standard; This does not directly establish cold-heading wire suitability or compliance with all product acceptance requirements. ; Footnote C: the nitrogen-analysis method is agreed between purchaser and supplier. ; Footnote J: Fe is calculated as 100 minus the sum of other specified elements and must be at least 39.5%.
