CONTAINED IN VOL. 01.01, 2017 Defines straight seam and spiral butt seam welded unannealed austenitic stainless steel tubular products intended for low and moderate temperatures and corrosive service where heat treatment is not necessary for corrosion resistance.

1.1This specification covers straight seam and spiral butt seam welded unannealed austenitic stainless steel tubular products intended for low and moderate temperatures and corrosive service where heat treatment is not necessary for corrosion resistance. Table 1 lists the five grades covered by this specification. The user of this specification should be aware that a minimum amount of testing and examination is required of the basic product. The user requiring additional testing or examination is referred to the supplemental requirements or Ordering Information, or both. Users requiring a tubular product with post-weld heat treatment or with radiographic examination are referred to Specification A312/A312M, A358/A358M, or A409/A409M, as applicable.

(A)New designation established in accordance with Practice E527 and SAE J1086.
(B)The carbon analysis shall be reported to the nearest 0.01 %, except for the low carbon (0.030) types, which shall be reported to the nearest 0.001 %.
(C)The titanium content shall be not less than five times the carbon content and not more than 0.70 %.
(D)The columbium plus tantalum content shall be not less than ten times the carbon content and not more than 1.10 %.

1.2This specification covers welded unannealed tubular products 3 in. [75 mm] through 48 in. [1200 mm] in outside diameter and in nominal wall thicknesses of 0.062 in. [1.57 mm] through 0.500 in. [12.70 mm] produced to this specification. Tubular products having other diameters or wall thickness, or both, may be furnished provided it complies with all other requirements of this specification.

1.3The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, SI units are shown in brackets. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining the values from the two systems may result in non-conformance with the standard. The inch-pound units shall apply unless the “M” designation of this specification is specified in the order.
