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.

United States13.3 If the requirements of this specification are in conflict with the requirements of Specification A788/A788M, therequirements of this specification shall prevail.3.4 If the forgings are intended for use under the ASME Boiler and Pressure Vessel Code
16、 at temperatures exceeding 1000F540C, then use Supplementary Requirement S7. Grain size requirements for service exceeding 1000F 540C should bespecified unless the required grade has the suffix “H.”4. Melting and Forging4.1 In addition to the melting and forging requirements of Specification A788/A7
17、88M, which may include SupplementaryRequirement S8, the following condition applies:4.1.1 A sufficient discard shall be made to secure freedom from injurious pipe and undue segregation.5. Machining5.1 Forged pressure vessels for steam power service shall have the inner surface machined or ground. Un
18、fired pressure vesselsshall have the inner surfaces sufficiently free of scale to permit inspection.5.2 When rough machining is performed, it may be done either before or after heat treatment.6. Heat Treatment6.1 Forgings shall be furnished in the solution treated condition. On completion of forging
19、 operations, the forgings shall besolution annealed and quenched in water, oil, or a polymer water solution. Direct quenching after completion of forging withoutsubsequent reheating to the temperatures prescribed in 6.2 6.5 is not permissible.6.2 For Grades F304H, F309H, F310H, F316H, F321H, F347H,
20、and F 348H, the minimum solution annealing temperature shallbe 1925F 1050C.6.3 Grades FXM-11 and FXM-19 shall be solution annealed at 1950F 1065C.6.4 Grade F46 shall be solution annealed in the temperature range of 2010 to 2140F 1100 to 1170C.6.5 The remaining grades in Table 1 shall be solution ann

Mechanical Properties8.1 RequirementsThe material shall conform to the requirements for mechanical properties prescribed in Table 2 or, ifapplicable, Supplementary Requirement S2. The largest obtainable tension t
25、est specimen as specified in Test Methods andDefinitions A370 or Test Methods A1058 shall be used.8.2 Number of TestsThe number and location of tests are based on the heat-treated weight of the forging(s) from the same heat,solution annealed in the same furnace charge.8.2.1 For forgings weighing les
26、s 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 prolongation of one of the forgings. Use of a separatelyforged test bar for the mechanical test specimens, instead of an integral p
27、rolongation, 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-treated cross sectionof the forgings it represents. The separately forged test bar shall be from the same heat as the forgings it
28、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 that completeheating records are available, a solution annealing charge may be considered as any continuous run not exceeding a
29、n 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 of the tension test specimen shall be parallel to the direction of major working of the forging, exceptwhen Supplementary Requi
30、rement 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 longitudinal axis of the tension test specimen shall be located midway between the parallel surfacesof the test extension, if added to
31、the periphery of disks, or midway between the center and surface of solid forgings.
