1、Designation: A965/A965M 12A965/A965M 13Standard Specification forSteel Forgings, Austenitic, for Pressure and HighTemperature Parts1This standard is issued under the fixed designation A965/A965M; the number immediately following the designation indicates the yearof original adoption or, in the case
2、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.1. Scope*1.1 This specification covers austenitic stainless steel forgings for boilers, pressure vessels,
3、 high temperature parts, andassociated equipment.1.2 Supplementary requirements are provided for use when additional testing, inspection, or processing is required. In addition,supplementary requirements from Specification A788/A788M may be specified when appropriate.1.3 This specification includes
4、the austenitic steel forgings that were a part of Specification A336/A336M.1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in eachsystem may not be exact equivalents; therefore, each system shall be used independently of the o
5、ther. Combining values from thetwo systems may result in non-conformance with the standard.1.5 Unless the order specifies the applicable “M” specification designation, the material shall be furnished to the inch-poundunits.1.6 This standard does not purport to address all of the safety concerns, if
6、any, associated with its use. It is the responsibilityof the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatorylimitations prior to use.2.

37、m to the requirements for mechanical properties prescribed in Table 2 or, ifapplicable, Supplementary Requirement S2. The largest obtainable tension test specimen as specified in Test Methods andDefinitions A370 shall be used.8.2 Number of TestsThe number and location of tests are based on the heat-
38、treated weight of the forging(s) from the same heat,solution annealed in the same furnace charge.8.2.1 For forgings weighing less than 5000 lb 2250 kg as heat treated, one tension test shall be required on the basis of onetest per heat in each heat treatment load. This test shall be taken from a pro
39、longation of one of the forgings. Use of a separatelyforged test bar for the mechanical test specimens, instead of an integral prolongation, is acceptable for forgings weighing less than5000 lb 2250 kg, provided that the heat-treated cross section of the test bar is not less than the maximum heat-tr
40、eated cross sectionof the forgings it represents. The separately forged test bar shall be from the same heat as the forgings it represents and shallaccompany the forgings during heat treatment.8.2.2 When heat treatment is performed in continuous type furnaces equipped with recording pyrometers, such
41、 that completeheating records are available, a solution annealing charge may be considered as any continuous run not exceeding an 8 h period.8.2.3 For forgings weighing over 5000 lb 2250 kg, as heat treated, one tension test shall be taken from a prolongation on eachforging.8.3 The longitudinal axis
42、 of the tension test specimen shall be parallel to the direction of major working of the forging, exceptwhen Supplementary Requirement S2 is specified. For upset disk forgings the longitudinal axis of the specimen shall be in eitherthe tangential or radial direction.8.3.1 The location of the longitu
43、dinal axis of the tension test specimen shall be located midway between the parallel surfacesof the test extension, if added to the periphery of disks, or midway between the center and surface of solid forgings. For hollowforgings, or those heat treated after boring, the specimen shall be located at
44、 midwall. For the special case of forgings that are heattreated solid, but are subsequently bored, the tension test specimen may be taken at the location of the minimum inside diameterafter boring instead of the mid-radius position.9. Grain Size9.1 For Grades F304H, F316H, F309H, F310H, F321H, F347H
45、, and F348H, the grain size of the forgings shall be ascertainedaccording to Test Methods E112, after solution treatment. One sample shall be examined for each tensile specimen required in 8.2and shall be taken from the tension test location. The grain size shall be number 6, or coarser, over at lea
46、st 75 % of the surveyedarea.10. Repair Welding10.1 Repair welding of forgings may be permitted but only at the option of the purchaser. Such repair welds shall be made inaccordance with Section IX of the ASME Boiler and Pressure Vessel Code.11. Marking11.1 The marking requirements of Specification A
47、788/A788M apply.A F46 shall have a maximum copper content of 0.50. Max. unless min or a range is indicated. Where ellipses (.) appear in this table, there is no requirement and theelement need not be analyzed for or reported.B F347 shall have a columbium content of not less than ten times the carbon
48、 content and not more than 1.10 %. (Alternatively, Alternatively, tantalum may be substitutedfor part of the columbium as approved by the purchaser.) purchaser.C F321 shall have a titanium content of not less than 5x (C+N) and not more than 0.70 %.D F321H shall have a titanium content of not less th
49、an 4x (C+N) and not more than 0.70 %.A965/A965M 134TABLE 2 Tensile RequirementsAustenitic SteelsGradeF304 F304H F304L F304N F304LN F309H F310 F310H F316 F316H F316L F316N F316LN F321 F321H F347 F347H F348 F348H FXM-19 FXM-11 F46Tensile strengthmin, ksi MPa704857048565450805507048570485755157048570485704856545080550704857048570485704857048570485704851006909062078100540690Yield strength(0.2 % offset),min, ksi MPa302053020
