Applicability and limitations
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.
