ASTMA 213 is an American Society for Testing and Materials (ASTM) standard for the specification of technical requirements and quality standards for seamless ferritic and austenitic alloy steel tubes and tubes for boilers, superheaters, and heat exchangers, the tubes are manufactured in seamless process in hot finished or cold finished in a wide range of sizes.
The ASTMA 213 standard applies to seamless ferritic and austenitic alloy steel tubes of minimum wall thicknesses, primarily for boilers, superheaters, and heat exchangers. The standard covers a wide range of tube grades including, but not limited to, T11, T12, T22 tubes, TP304, TP316L, TP321 tubes, etc. Detailed specifications for these tubes are listed in the relevant sections of the standard, containing grade, size, finishes, test and other terms, the equivalent standard is ASME SA213, and the latest version of the standard is ASTM A213/A213M-22.

ASRM A213 Tube Manufacturing Processes
The tubes shall be produced through the hot-finished or cold-finished seamless process.
Heat treatment shall be done separately and in addition to heating for hot forming.
The ferritic alloy and ferritic stainless steels shall be reheated. austenitic stainless steel tubes shall be furnished in the heat-treated condition.
Tubes may be individually quenched in water or rapidly cooled by other means.
Tubes shall be pickled free of scale. When bright annealing is used, pickling is not necessary.
Complete tests should be conducted conforming to ASTM A213 or ASTM A1016.
We are a professional ASTM A213 seamless tube manufacturer & supplier, having the capability to produce a wide range size seamless tubes for heat exchanger systems, the manufacturing process starts from the extrusion of the billet, by cold rolling and cold drawn methods to control size and tolerance, heat treatment will be finished after cold working to achieve original steel properties, which improve high-temperature resistance and corrosion resistance, then tubes should be under pickling passivation condition.

ASTM A213 Seamless Tubes
Standard Specification for Seamless Ferritic and Austenitic Alloy-Steel Boiler, Superheater, and Heat-Exchanger Tubes
1.1 This specification covers seamless ferritic and austenitic steel boiler, superheater, and heat-exchanger tubes, designated Grades T91, 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 SI units or inch-pound units are to be regarded separately as standard. Within the text, the 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 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.
TABLE 1 Chemical Composition Limits, %A, for Low Alloy SteelA Maximum, unless range or minimum is indicated. Where ellipses (…) appear in this table, there is no requirement, and analysis for the element need not be determined or reported.
B It is permissible to order T2 and T12 with a sulfur content of 0.045 max. See 16.3.
C Alternatively, in lieu of this ratio minimum, the material shall have a minimum hardness of 275 HV in the hardened condition, defined as after austenitizing and cooling to room temperature but prior to tempering. Hardness testing shall be performed at mid-thickness of the product. Hardness test frequency shall be two samples of product per heat treatment lot and the hardness testing results shall be reported on the material test report.
