ASTM A213

ASTM A213 Alloy Tubes are been widely used in high temperature services especially for the boiler and superheater.

ASTM A213 Alloy Tubes material could be in alloy steel and stainless steel, and manufactured in seamless of hot rolled or cold drawn. So this pipe usually used in very important places and the price is much higher than normal carbon pipes.

Sunny Steel Supply stocks a full range of the following ASTM A213 grades:

Main grades: ASTM A213 T5, T5b, T9, T11, T91 and T22

Size range:

SA 213 standard specification for seamless ferritic and austenitic alloy-steel boiler,super heater,and heat-exchanger tubes.

1. Surface state:
Austenitic steel pipe should be washed to remove the scale, when the use of bright annealing, you do not need pickling.

2. Chemical analysis of finished products:
It shall be analyzed from one billet or one pipe per furnace, and the chemical composition determined accordingly shall meet the specified requirements.

3. Mechanical test and grain size:
(1) Tensile test:Such as each batch of steel pipe ≤ 50 root, then take a sample for tensile test; each batch of steel pipe> 50, then two steel pipes should take two samples for tensile test.
(2) Flattening test: in each batch of a finished tube at both ends of each sample to take a flattening test, but the root can not used as a flaring sample.
(3) Flaring test: in each batch of a finished tube at both ends of a sample for a flaring test, but the root canal can not be used as a flattening sample.
(4) Hardness test: from each batch of two tubes on the sample to do Brinell or Rockwell hardness test.
(5) Water pressure test: each pipe should be hydrostatic test. When the buyer is specified, a non-destructive test may be used instead.
(6) Grain size: according to ASME E112 standard test.

ASTM A213/A213M -17 Standard Specification for Seamless Ferritic and Austenitic Alloy-Steel Boiler, Superheater, and Heat-Exchanger Tubes. This specification covers seamless ferritic and austenitic steel boiler, superheater, and heat-exchanger tubes. 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. The tubes shall be made by the seamless process and shall be either hot finished or cold finished, as specified. Grade TP347HFG shall be cold finished. Heat treatment shall be done separately and in addition to heating for hot forming. The ferritic alloy and ferritic stainless steels shall be reheated. On the other hand, austenitic stainless steel tubes shall be furnished in the heat-treated condition. Alternatively, immediately after hot forming, while the temperature of the tubes is not less than the minimum solution temperature, tubes may be individually quenched in water or rapidly cooled by other means. Tension test, hardness test, flattening test, and flaring test shall be done to each tube. Also, each tube shall be subjected to the nondestructive electric test or hydrostatic test. This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

Scope

1.1 This specification2 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.

(A) 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.
(D) The terms Niobium (Nb) and Columbium (Cb) are alternate names for the same element.
(A) Maximum, unless a range or minimum is indicated. Where ellipses (...) appear in this table, there is no minimum and analysis for the element need not be determined or reported.
(B) The method of analysis for Nitrogen shall be a matter of agreement between the purchaser and the producer.
(C) For these alloys, there is no common grade designation. The UNS number uniquely identifies these alloys.
(D) For small diameter or thin walls, or both, where many drawing passes are required, a carbon maximum of 0.040% is necessary in Grades TP304L, TP304LN, TP316L, and TP316LN.
(E) Grade S30434 shall have (Ti + 1/2 Nb) of not less than 2 times and not more than 4 times the carbon content.
(F) Grade TP347LN shall have an Nb content of not less than 15 times the carbon content.
(G) Grade TP348 shall have an Nb + Ta content of not less than 10 times the carbon content and not more than 1.10%.
(H) Grade TP348H shall have an Nb + Ta content of not less than 8 times the carbon content and not more than 1.10%.
(I) Iron shall be determined arithmetically by difference of 100 minus the sum of the other specified elements.
(J) Al + Ti shall be 0.85 % min; 1.20 % max.
(K) Grade TP444 shall have Ni + Cu = 1.00 max.
(L) Grade TP444 shall have Ti + Nb content not less than 0.20 + 4(C+N) and not more than 0.80 %.
(M) N08020 shall have an Nb + Ta content of not less than 8 times the carbon content and not more than 1.00%.
(N) The terms Niobium (Nb) and Columbium (Cb) are alternate names for the same element.

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.
