S31727

Composition alloy: S31727. Table 2, mass fraction wt%; values are maxima except where explicit ranges are given. Ellipses are not replaced with zero. The source actually read is ASME BPVC.II.A-2023 SA814; the cover explicitly states that it is identical to ASTM A814/A814M-15(2019). The analytical method for N is subject to agreement between purchaser and supplier. Product-analysis tolerances under A480/A480M require separate verification and are not incorporated into this table. This standard covers cold-worked welded stainless steel pipe and does not automatically approve a cold-heading product.

Table 1 ladle composition, mass fraction %; a single value without a range or lower limit is a maximum, and unspecified elements are not filled with zero. Cb and Nb are the same element; where both a formula and a fixed limit apply, use the more restrictive limit. This is a plate, sheet and strip standard; suitability for cold-heading wire and actual supply require separate verification. Clause 4.1 also requires applicable provisions of ASTM A480/A480M. This record shows ladle composition from Table 1; it does not mean that A480 or all product acceptance requirements have been fully checked.

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.
