ASTM/ASME A/SA213

SPECIFICATION FOR SEAMLESS FERRITIC AND AUSTENITIC ALLOY-STEEL BOILER, SUPERHEATER, AND HEAT-EXCHANGER TUBES. 1. Scope 1.1 This specification covers seamless ferritic and austenitic steel boiler, superheater, and heat-exchanger tubes, designated Grades T5, TP304, etc. These steels are listed in Tables 1 and 2. 1.2 Grades containing the letter, H, in their designation, have requirements different from those of similar grades not containing the letter, H. These different requirements provide higher creep-rupture strength than normally achievable in similar grades without these different requirements. 1.3 The tubing sizes and thicknesses usually furnished to this specification are 1⁄8 in. [3.2 mm] in inside diameter to 5 in. [127 mm] in outside diameter and 0.015 to 0.500 in. [0.4 to 12.7 mm], inclusive, in minimum wall thickness or, if specified in the order, average wall thickness. Tubing having other diameters may be furnished, provided such tubes comply with all other requirements of this specification. 1.4 The values stated in either inch-pound units or SI units are to be regarded separately as standard.Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values from the two systems may result in nonconformance with the specification. The inch-pound units shall apply unless the “M” designation of this specification is specified in the order.

ASTM/ASME A/SA249

SPECIFICATION FOR WELDED AUSTENITIC STEEL BOILER, SUPERHEATER, HEAT-EXCHANGER, AND CONDENSER TUBES. 1. Scope 1.1 This specification covers nominal-wall-thickness welded tubes and heavily cold worked welded tubes made from the austenitic steels listed in Table 1, with various grades intended for such use as boiler, superheater, heat exchanger, or condenser tubes. 1.2 Grades TP304H, TP309H, TP309HCb, TP310H, TP310HCb, TP316H, TP321H, TP347H, and TP348H are modifications of Grades TP304, TP309S, TP309Cb, TP310S, TP310Cb, TP316, TP321, TP347, and TP348, and are intended for high-temperature service such as for superheaters and reheaters. 1.3 The tubing sizes and thicknesses usually furnished to this specification are 1⁄8 in. [3.2 mm] in inside diameter to 12 in. [304.8 mm] in outside diameter and 0.015 to 0.320 in. [0.4 to 8.1 mm ], inclusive, in wall thickness. Tubing having other dimensions may be furnished, provided such tubes comply with all other requirements of this specification. 1.4 Mechanical property requirements do not apply to tubing smaller than 1⁄8 in. [3.2 mm] in inside diameter or 0.015 in. [0.4 mm] in thickness. 1.5 Optional supplementary requirements are provided and, when one or more of these are desired, each shall be so stated in the order. 1.6 The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values from the two systems may result in nonconformance with the specification. The inch-pound units shall apply 377 unless the “M” designation of this specification is specified in the order. 1.7 The following safety hazards caveat pertains only to the test method described in the Supplementary Requirements of this specification. This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. A specific warning statement is given in Supplementary Requirement S7, Note S7.1.

ASTM/ASME A/SA358Cl1-5

SPECIFICATION FOR ELECTRIC-FUSION-WELDED AUSTENITIC CHROMIUM-NICKEL ALLOY STEEL PIPE FOR HIGH-TEMPERATURE SERVICE
All products furnished under this SA specification are intended for application under the rules of Section III or Section VIII-1 of the ASME Boiler and Pressure Vessel Code. Manufacture of such products is limited to manufacturers who hold the appropriate ASME Certificate of Authorization and Code Symbol Stamp. In addition to conforming to this specification, the manufacturer shall meet all applicable requirements of Section III or Section VIII-1 if applicable of the Code. The plate used to fabricate the pipe shall conform to SA-240. The joints shall be full penetration butt welds as obtained by double welding or by other means which will obtain the same quality of deposited and weld metal on the inside and outside. Welds using metal backing strips which remain in place are excluded. The product is subject to all requirements of Section III or Section VIII-1 if applicable of the Code including welding, heat treatment, nondestructive examination, authorized inspection at the point of manufacture, and application of the Code Symbol Stamp. The applicable ASME Partial Data Report Form signed by an Authorized Inspector and a certified mill test report shall be furnished for each lot of pipe. The term “lot” applies to all pipe of the same mill heat of material and wall thickness which is heat treated in one furnace charge. For pipe that is not heat treated, or that is heat treated in a continuous furnace, a lot shall consist of each 200 ft (61 m) or fraction thereof of all pipe of the same mill heat material and wall thickness subjected to the same heat treatment. For pipe that is heat treated in a batchtype furnace that is automatically controlled within a 50°F range and is equipped with recording pyrometers so that the heating records are available, a lot may be defined the same as for continuous furnaces. Each length of pipe shall be marked in such a manner as to identify each such piece with the lot and the certified mill test report.

Scope 1.1 This specification covers forged low alloy and stainless steel piping components for use in pressure systems. Included are flanges, fittings, valves, and similar parts to specified dimensions or to dimensional standards, such as the ASME specifications that are referenced in Section 2. 1.2 For bars and products machined directly from bar, refer to Specifications A 479/A 479M and A 739 for the similar grades available in those specifications. Products made to this specification are limited to a maximum weight of 10 000 lb [4540 kg]. For larger products and products for other applications, refer to Specifications A 336/A 336M and A 965/A 965M for the similar ferritic and austenitic grades, respectively, available in those specifications. 1.3 Several grades of low alloy steels and ferritic, martensitic, austenitic, and ferritic-austenitic stainless steels are included in this specification. Selection will depend upon design and service requirements. 1.4 Supplementary requirements are provided for use when additional testing or inspection is desired. These shall apply only when specified individually by the purchaser in the order. 1.5 This specification is expressed in both inch-pound units and in SI units. However, unless the order specifies the applicable “M” specification designation (SI units), the material shall be furnished to inch-pound units. 1.6 The values stated in either inch-pound units or SI units are to be regarded separately as the standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore,
