Applicability and limitations
Composition alloy: S30400. 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.
