Control factors of 4.4.2.2 shall apply. 3.4.2 Each master heat shall be qualified by evaluation of chemical, tensile, and stress-rupture specimens. 3.4.2.1 If replenishments are made at remelt as in 3.2.4, frequency of sampling and testing used by the vendor for qualification t

21、o 3.4.2 shall be acceptable to purchaser. 3.4.2.2 Tensile and stress-rupture tests of 3.4.2 are not required if these tests are conducted using integrally-cast specimens (4.3.3.2) or specimens machined-from-casting (4.3.3.3). 3.4.3 Chemical Analysis Specimens Shall be of any convenient size and shap

22、e. 3.4.4 Tensile and Stress-Rupture Specimens Shall be of standard proportions in accordance with ASTM E 8/E 8M (See 8.3), and ASTM E 139, respectively. 3.4.4.1 Separately-cast and integrally-cast specimens may be either cast to size, and/or cast oversize and subsequently machined to 0.250-inch (6.3

Properties other than those listed may be defined

27、as specified in AMS2362. 3.6.2.1 Specimens, maintained at 1800 F 3 (982 C 2) while a load sufficient to produce an initial axial stress of 22.0 ksi (152 MPa) or higher is applied continuously, shall not rupture in less than 30 hours. The test shall be continued to rupture without change of load. Elo

28、ngation after rupture, measured at room temperature, shall be not less than 5% in 4D. 3.6.2.2 The test of 3.6.2.1 may be conducted using incremental loading. In such case, the load required to produce an initial axial stress of 22.0 ksi (152 MPa) or higher shall be used to rupture or for 30 hours, w

29、hichever occurs first. After the 30 hours and at intervals of 8 hours, minimum, thereafter, the stress shall be increased in increments of 2.0 ksi (14.0 MPa). Time to rupture and elongation requirements shall be as specified in 3.6.2.1. 3.6.3 Hardness Not applicable. 3.7 Quality 3.7.1 Castings, as r

30、eceived by purchaser, shall be uniform in quality and condition, sound, and free from foreign materials and from imperfections detrimental to usage of the castings. Castings shall be free of cracks, laps, hot tears, and cold shuts, and free of scale and other process induced surface contamination wh

31、ich would obscure defects. 3.7.2 Castings shall be produced under radiographic control. This control shall consist of radiographic examination of each casting part number until foundry manufacturing controls in accordance with 4.4.2 have been established. Additional radiography shall be conducted in

32、 accordance with the frequency of inspection specified by purchaser, or as necessary to ensure continued maintenance of internal quality. 3.7.2.1 Radiographic inspection shall be conducted in accordance with ASTM E 1742/E 1742M or other method specified by purchaser. SAE INTERNATIONAL AMS5391H Page

33、5 of 9 3.7.3 When specified, castings shall be subjected to fluorescent penetrant inspection in accordance with ASTM E 1417/E 1417M or other method specified by purchaser. 3.7.4 Acceptance standards for radiographic, fluorescent penetrant, visual, and other inspection methods shall be as agreed upon

34、 by purchaser and vendor (See 8.2.9). AMS2175 may be used to specify acceptance standards (casting grade) and frequency of inspection (casting class). 3.7.4.1 When acceptance standards are not specified, Grade C of AMS2175 as applicable to steel castings shall apply for each specified method of insp

35、ection. 3.7.5 Castings shall not be peened, plugged, impregnated, or welded unless authorized by purchaser. 3.7.5.1 When authorized by purchaser, welding in accordance with AMS2694 or other welding program acceptable to purchaser may be used. 4. QUALITY ASSURANCE PROVISIONS 4.1 Responsibility for in

36、spection The vendor of castings shall supply all samples for vendors tests and shall be responsible for the performance of all required tests. Purchaser reserves the right to sample and to perform any confirmatory testing deemed necessary to ensure that the castings conform to specified requirements

37、. 4.2 Classification of Tests 4.2.1 Acceptance Tests Composition (3.1), room temperature tensile properties (3.6.1), stress rupture properties (3.6.2) and the applicable requirements of quality (3.7) are acceptance tests and shall be performed as specified in 4.3. 4.2.2 Periodic Tests Radiographic s

38、oundness (3.7.2) is a periodic test and shall be performed at a frequency selected by the vendor unless frequency of testing is specified by purchaser. 4.2.3 Preproduction Tests All technical requirements are preproduction tests and shall be performed on sample castings (4.3.2), when a change in con

39、trol factors occurs (4.4.2.2), and when purchaser deems confirmatory testing to be required. 4.3 Sampling and Testing The minimum testing performed by vendor shall be in accordance with the following: 4.3.1 One chemical analysis specimen or a casting from each master heat shall be tested for conform

40、ance with Table 1; if 3.4.2.1 applies, test frequency shall be acceptable to purchaser. 4.3.2 One preproduction casting in accordance with 4.4 shall be tested to requirements of the casting drawing and to all technical requirements. 4.3.2.1 Dimensional inspection sample quantity shall be as specifie

41、d by purchaser. 4.3.3 Tensile property and stress-rupture tests shall be conducted to determine conformance with 3.6.1 and 3.6.2. Sampling and test frequency is dependent upon the type and origin of the specimen specified by purchaser (See 3.4.4 and 3.6) or selected by vendor (See 4.3.3.4). When 3.4

42、.2.1 applies, specimen source and test frequency shall be acceptable to purchaser. 4.3.3.1 For separately-cast specimens in the as-cast condition, two specimens from each master heat shall be tested; one for conformance to Table 2 and one for conformance to 3.6.2. SAE INTERNATIONAL AMS5391H Page 6 o

43、f 9 4.3.3.2 For integrally-cast specimens in the as-cast condition, two specimens shall be randomly selected from each lot and tested for conformance with properties specified by purchaser (See 3.6 and 8.5). 4.3.3.3 For specimens machined-from-casting, one casting shall be randomly selected from eac

44、h lot and tested in the as-cast condition at each location shown on the engineering drawing for conformance with properties specified by purchaser (See 3.6 and 8.5). 4.3.3.3.1 When size and location of specimens are not shown, two specimens shall be tested, one from the thickest section and one from

45、 the thinnest section. Once established under 4.4.2.2, test locations may be changed only as agreed upon by purchaser and vendor. 4.3.3.4 When acceptable to purchaser, specimens machined-from-casting may be used in lieu of both separately-cast and integrally-cast specimens, and integrally-cast speci

46、mens may be used in lieu of separately-cast specimens. In each case, the resultant properties shall conform to the requirements of 3.6 or to alternative requirements specified by purchaser (See 8.5). 4.3.3.4.1 When specimens are selected for test as in 4.3.3.4 from an origin other than that specifie

47、d by purchaser, vendor shall include in the report of 4.5 a description of the source of the specimen that was tested. 4.3.3.5 When casting size, section thickness, gating method, or other factors do not permit conformance with 4.3.3.2 or 4.3.3.3, sampling and testing shall be agreed upon by purchas

48、er and vendor. 4.3.4 Castings shall be inspected in accordance with 3.7 to the methods, frequency, and acceptance standards specified by purchaser. 4.4 Approval 4.4.1 Sample casting(s) from new or reworked master patterns produced under the casting procedure of 4.4.2 shall be approved by purchaser b

49、efore castings for production use are supplied, unless such approval be waived by purchaser. 4.4.2 For each casting part number, vendor shall establish parameters for process control factors that will consistently produce castings and test specimens meeting the requirements of the casting drawing and this specification. These parameters shall constitute the approved casting procedure and shall be used for production of
