S30815

Composition alloy: S30815. 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.

Based on SAE J405 JUN1998 original Table 1; mass fraction wt%. Note 1: a value without a range or lower limit is a maximum; a dash means unspecified, not zero. Note 5: Cb and Nb denote the same element; verify alloying elements against the corresponding UNS row and additional conditions. Note 4: carbon is generally reported to 0.01%, and low-carbon types to 0.001%; this is reporting precision and does not relax composition limits. Original Table 1 type names may include common names or ASTM-naming footnotes; create search aliases only for explicit same-row correspondences, without implying cross-standard equivalence. 1998 is the actual composition basis; the specified newer edition has not been checked, so consistency between editions is not assumed.

Table 1: heat-analysis composition, mass fraction %. A single value without a stated range or lower bound is a maximum; unspecified elements are not assigned zero. Cb and Nb refer to the same element. Where a formula and fixed limits both apply, use the stricter limit. 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 applicable provisions of ASTM A480/A480M. This record displays heat composition from Table 1; it does not establish complete verification of A480 or all product-acceptance requirements. Other elements as printed: Ce 0.03–0.08; see the constraints 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.
