Standard Speci?cation for

Forged or Rolled Alloy and Stainless Steel Pipe Flanges, Forged Fittings, and Valves and Parts for High-Temperature Service1
This standard is issued under the ?xed designation A182/A182M; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A superscript epsilon (?) indicates an editorial change since the last revision or reapproval. This standard has been approved for use by agencies of the Department of Defense.

1. Scope* 1.1 This speci?cation2 covers forged low alloy and stainless steel piping components for use in pressure systems. Included are ?anges, ?ttings, valves, and similar parts to speci?ed dimensions or to dimensional standards, such as the ASME speci?cations that are referenced in Section 2. 1.2 For bars and products machined directly from bar (other than those directly addressed by this speci?cation; see 6.4), refer to Speci?cations A479/A479M and A739 for the similar grades available in those speci?cations. Products made to this speci?cation are limited to a maximum weight of 10 000 lb [4540 kg]. For larger products and products for other applications, refer to Speci?cations A336/A336M and A965/A965M for the similar ferritic and austenitic grades, respectively, available in those speci?cations. 1.3 Several grades of low alloy steels and ferritic, martensitic, austenitic, and ferritic-austenitic stainless steels are included in this speci?cation. Selection will depend upon design and service requirements. Several of the ferritic/austenitic (duplex) grades are also found in Speci?cation A1049/ A1049M. 1.4 Supplementary requirements are provided for use when additional testing or inspection is desired. These shall apply only when speci?ed individually by the purchaser in the order. 1.5 This speci?cation is expressed in both inch-pound units and in SI units. However, unless the order speci?es the applicable ※M§ speci?cation designation (SI units), the material shall be furnished to inch-pound units. 1.6 The values stated in either SI units or inch-pound units are to be regarded separately as the standard. Within the text,

8. Chemical Composition 8.1 A chemical heat analysis in accordance with Speci?cation A961/A961M shall be made and conform to the chemical composition prescribed in Table 2. 8.2 Grades to which lead, selenium, or other elements are added for the purpose of rendering the material free-machining shall not be used. 8.3 Starting material produced to a speci?cation that speci?cally requires the addition of any element beyond those listed in Table 2 for the applicable grade of material is not permitted. 8.4 Steel grades covered in this speci?cation shall not contain an unspeci?ed element, other than nitrogen in stainless steels, for the ordered grade to the extent that the steel conforms to the requirements of another grade for which that element is a speci?ed element having a required minimum content. For this requirement, a grade is de?ned as an alloy described individually and identi?ed by its own UNS designation or Grade designation and identi?cation symbol in Table 2. 8.5 Product Analysis〞The purchaser may make a product analysis on products supplied to this speci?cation in accordance with Speci?cation A961/A961M. 9. Mechanical Properties 9.1 The material shall conform to the requirements as to mechanical properties for the grade ordered as listed in Table 3. 9.2 Mechanical test specimens shall be obtained from production forgings, or from separately forged test blanks prepared from the stock used to make the ?nished product. In either case, mechanical test specimens shall not be removed until after all heat treatment is complete. If repair welding is required, test specimens shall not be removed until after post-weld heat treatment is complete, except for ferritic grades when the post-weld heat treatment is conducted at least 50 ∼F [30 ∼C] below the actual tempering temperature. When test blanks are used, they shall receive approximately the same working as the ?nished product. The test blanks shall be heat treated with the ?nished product and shall approximate the maximum cross section of the forgings they represent. 9.3 For normalized and tempered, or quenched and tempered forgings, the central axis of the test specimen shall correspond to the 1?4 T plane or deeper position where T is the maximum heat-treated thickness of the represented forging. In addition, for quenched and tempered forgings, the mid-length of the test specimen shall be at least T from any second heat-treated surface. When the section thickness does not permit this positioning, the test specimen shall be positioned as near as possible to the prescribed location, as agreed to by the purchaser and the supplier. 9.3.1 With prior purchase approval, the test specimen for ferritic steel forgings may be taken at a depth (t) corresponding to the distance from the area of signi?cant stress to the nearest heat-treated surface and at least twice this distance (2 t) from any second surface. However, the test depth shall not be nearer to one treated surface than 3?4 in. [19 mm] and to the second treated surface than 11?2 in. [38 mm]. This method of test specimen location would normally apply to contour-forged parts, or parts with thick cross-sectional areas where 1?4 T 3

T testing (see 9.3) is not practical. Sketches showing the exact test locations shall be approved by the purchaser when this method is used. 9.3.2 Metal Buffers〞The required distances from heattreated surfaces may be obtained with metal buffers instead of integral extensions. Buffer material may be carbon or low-alloy steel, and shall be joined to the forging with a partial penetration weld that seals the buffered surface. Specimens shall be located at 1?2-in. [13-mm] minimum from the buffered surface of the forging. Buffers shall be removed and the welded areas subjected to magnetic particle test to ensure freedom from cracks unless the welded areas are completely removed by subsequent machining. 9.4 For annealed low alloy steels, ferritic stainless steels, and martensitic stainless steels, and also for austenitic and ferritic-austenitic stainless steels, the test specimen may be taken from any convenient location. 9.5 Tension Tests: 9.5.1 Low Alloy Steels and Ferritic and Martensitic Stainless Steels〞One tension test shall be made for each heat in each heat treatment charge. 9.5.1.1 When the heat-treating cycles are the same and the furnaces (either batch or continuous type) are controlled within 625 ∼F [614 ∼C] and equipped with recording pyrometers so that complete records of heat treatment are available, then only one tension test from each heat of each forging type (see Note 1) and section size is required, instead of one test from each heat in each heat-treatment charge.
NOTE 1〞※Type§ in this case is used to describe the forging shape such as a ?ange, ell, tee, and the like.

9.5.2 Austenitic and Ferritic-Austenitic Stainless Steel Grades〞One tension test shall be made for each heat. 9.5.2.1 When heat treated in accordance with 7.1, the test blank or forging used to provide the test specimen shall be heat treated with a ?nished forged product. 9.5.2.2 When the alternative method in 7.3.1 is used, the test blank or forging used to provide the test specimen shall be forged and quenched under the same processing conditions as the forgings they represent. 9.5.3 Testing shall be performed in accordance with Test Methods and De?nitions A370 using the largest feasible of the round specimens. The gage length for measuring elongation shall be four times the diameter of the test section. 9.6 Hardness Tests: 9.6.1 Except when only one forging is produced, a minimum of two pieces per batch or continuous run as de?ned in 9.6.2 shall be hardness tested in accordance with Test Methods and De?nitions A370 to ensure that the forgings are within the hardness limits given for each grade in Table 3. The purchaser may verify that the requirement has been met by testing at any location on the forging provided such testing does not render the forging useless. 9.6.2 When the reduced number of tension tests permitted by 9.5.1.1 is applied, additional hardness tests shall be made on forgings or samples, as de?ned in 9.2, scattered throughout the load (see Note 2). At least eight samples shall be checked from each batch load, and at least one check per hour shall be made from a continuous run. When the furnace batch is less than

A182/A182M 每 10a
eight forgings, each forging shall be checked. If any check falls outside the prescribed limits, the entire lot of forgings shall be reheat treated and the requirements of 9.5.1 shall apply.
NOTE 2〞The tension test required in 9.5.1 is used to determine material capability and conformance in addition to verifying the adequacy of the heat-treatment cycle. Additional hardness tests in accordance with 9.6.2 are required when 9.5.1.1 is applied to ensure the prescribed heat-treating cycle and uniformity throughout the load.

9.6.3 When the alternative to the Ti/N ratio limit for F23 is applied, (see Note P in Table 2), a minimum of two pieces per batch or continuous run as de?ned in 9.6.2 shall be hardness tested, in the hardened condition (see 3.2.1), to ensure that the

forgings are within the hardness limit given for F23 in Note P of Table 2. The test samples shall be taken at the mid thickness of the thickest section of the product. Testing shall be performed in accordance with the Test Method E92 or with Test Methods and De?nitions A370. 9.7 Notch Toughness Requirements〞Grades F 3V, F 3VCb, and F 22V. 9.7.1 Impact test specimens shall be Charpy V-notch Type, as shown in Fig. 11a of Test Methods and De?nitions A370. The usage of subsize specimens due to material limitations must have prior purchaser approval.

All values are maximum unless otherwise stated. Where ellipses (...) appear in this table, there is no minimum and analysis for the element need not be determined or reported. Grade F 2 was formerly assigned to the 1 % chromium, 0.5 % molybdenum grade which is now Grade F 12. C The present grade F 5a (0.25 max carbon) previous to 1955 was assigned the identi?cation symbol F 5. Identi?cation symbol F 5 in 1955 was assigned to the 0.15 max carbon grade to be consistent with ASTM speci?cations for other products such as pipe, tubing, bolting, welding ?ttings, and the like. D Applies to both heat and product analyses. E For Grade F22V, rare earth metals (REM) may be added in place of calcium, subject to agreement between the producer and the purchaser. In that case the total amount of REM shall be determined and reported. F The ratio of Titanium to Nitrogen shall be $ 3.5. Alternatively, in lieu of this ratio limit, Grade F23 shall have a minimum hardness of 275 HV (26 HRC, 258 HBW) in the hardened condition (see 3.2.1). Hardness testing shall be performed in accordance with 9.6.3, and the hardness testing results shall be reported on the material test report (see 17.2.5). G Naming system developed and applied by ASTM. H Grade F XM-27Cb shall have a nickel plus copper content of 0.50 max %. Product analysis tolerance over the maximum speci?ed limit for carbon and nitrogen shall be 0.002 %. I Grades F 304, F 304L, F 316, and F 316L shall have a maximum nitrogen content of 0.10 %. J Grades F 304N, F 316N, F 304LN, and F 316LN shall have a nitrogen content of 0.10 to 0.16 %. K Grade F 316Ti shall have a titanium content not less than ?ve times the carbon plus nitrogen content and not more than 0.70 %. L Grade F 321 shall have a titanium content of not less than ?ve times the carbon content and not more than 0.70 %. M Grade F 321H shall have a titanium content of not less than four times the carbon content and not more than 0.70 %. N Grades F 347 and F 348 shall have a columbium content of not less than ten times the carbon content and not more than 1.10 %. O Grades F 347H and F 348H shall have a columbium content of not less than eight times the carbon content and not more than 1.10 %. P Grade F347LN shall have a columbium content of not less than 15 times the carbon content. Q % Cr + 3.3 3 % Mo + 16 3 % N = 40 min.
