sA213 standard specification for seamless ferritic and austenitic alloy-steel boiler,super heater,and heat-exchanger tubes.

1. Surface state:
应洗涤奥氏体钢管以去除尺度，当使用明亮的退火时，您不需要腌制。

2. Chemical analysis of finished products:
应从一个钢坯或一个管道分析它，并且确定的化学成分应符合指定的要求。

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无缝铁质和奥氏体合金钢锅炉，过热器和热交换器管的标准规范。该规范涵盖了无缝铁素体和奥氏体钢锅炉，过热器和热交换器管。在其指定中包含字母H的等级与不包含字母H的类似等级的要求不同。这些不同的要求提供的蠕变解脱强度比在没有这些不同要求的相似等级中正常达到的更高。管子应通过无缝过程制成，并应按照指定的方式进行热成品或冷完成。TP347HFG级应冷结束。热处理应分别进行，除了加热热形成外。铁质合金和铁质不锈钢应被重新加热。另一方面，奥氏体不锈钢管应在热处理状态下提供。或者，在热形成后立即，虽然管的温度不低于最低溶液温度，但管子可以单独淬灭水或通过其他方式迅速冷却。应对每个管进行张力测试，硬度测试，扁平测试和燃烧测试。 Also, each tube shall be subjected to the nondestructive electric test or hydrostatic test.

scope

1.1此规格2涵盖了无缝铁素体和奥斯丁钢锅炉，过热器和热量交换器，指定的T5级，TP304等。这些钢列在表1和2中。

(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）或者，代替该比率最小值，该材料在硬化条件下的最小硬度应为275 hv，定义为在奥氏体化和冷却为室温，但在回火之前定义。硬度测试应在产品的中间厚度进行。硬度测试频率应为每个热处理量的两个产品样本，并且应在材料测试报告中报告硬度测试结果。
（d）术语niobium（nb）和哥伦布（CB）是同一元素的替代名称。
(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）对于这些合金，没有共同的年级名称。UNS数字独特地标识了这些合金。
（d）对于需要许多绘图的小直径或薄壁，或两者兼而有之，TP304L，TP304LN，TP316L和TP316LN的碳最大为0.040％。
（e）S30434级的（Ti + 1/2 nb）不少于2次，不超过碳含量的4倍。
(F) Grade TP347LN shall have an Nb content of not less than 15 times the carbon content.
（g）TP348级的NB + TA含量应不少于碳含量的10倍，不超过1.10％。
（H）TP348H级的NB + TA含量应不少于碳含量的8倍，而不得超过1.10％。
(I) Iron shall be determined arithmetically by difference of 100 minus the sum of the other specified elements.
（J）Al + Ti应为0.85％；最大1.20％。
（k）TP444级应具有Ni + Cu = 1.00最大。
(L) Grade TP444 shall have Ti + Nb content not less than 0.20 + 4(C+N) and not more than 0.80 %.
（M）N08020的NB + TA含量应不少于碳含量的8倍，不超过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通常提供给该规范的管道尺寸和厚度为1/8英寸。[3.2毫米]内直径至5英寸。[127毫米]外直径为0.015至0.500至0.500英寸[0.4至12.7 mm]在最小壁厚或按顺序指定的情况下，平均壁厚。可以提供具有其他直径的管，只要该管道符合本规范的所有其他要求。

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.
