26、 If the conductivity is 38.0 to 39.9% IACS (22.0 to 23.1 MS/m), if the longitudinal tensile properties meet specified requirements, and if the longitudinal yield strength does not exceed the specified minimum by more than 11.9 ksi (82 MPa), rings are acceptable. 3.3.2.3 If the conductivity is below
27、40.0% IACS and the longitudinal yield strength exceeds the specified minimum value by more than 11.9 ksi (82 MPa), rings shall be given additional precipitation heat treatment. If after such treatment, rings meet the requirements of 3.3.1.1 and 3.3.2.1 or 3.3.2.2, rings are acceptable. 3.3.2.4 If th
28、e conductivity is below 38.0% IACS (22.0 MS/m), rings are not acceptable but may be re-heat treated or given additional precipitation heat treatment to meet the requirements of 3.3.1.1 and 3.3.2.1 or 3.3.2.2. 3.3.3 Stress-Corrosion Cracking Resistance: Specimens, cut from a ring so that the axis of
29、loading of the specimen is parallel to the short-transverse direction of the ring, shall show no evidence of stress-corrosion cracking when stressed to 75% of the specified minimum longitudinal yield strength.3.4 Quality: Rings, as received by purchaser, shall be uniform in quality and condition, so
30、und, and free from foreign materials and from imperfections detrimental to usage of the rings.

31、ONS: 4.1 Responsibility for Inspection: The vendor of rings 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 rings conform
32、to specified requirements.4.2 Classification of Tests: 4.2.1 Acceptance Tests: Composition (3.1), longitudinal tensile properties (3.3.1.1), and conductivity (3.3.2) are acceptance tests and, except for composition, shall be performed on each lot. 4.2.2 Periodic Tests: Transverse tensile properties
33、(3.3.1.2 and 3.3.1.3) and stress-corrosion resistance (3.3.3) are periodic tests and shall be performed at a frequency selected by the vendor unless frequency of testing is specified by purchaser. 4.3 Sampling and Testing: Shall be in accordance with AMS 2355. 4.4 Reports: The vendor of rings shall
34、furnish with each shipment a report stating that the product conforms to the composition, tolerances, and nondestructive tests, and showing the numerical results of tests on each inspection lot to determine conformance to the other acceptance test requirements. This report shall include the purchase
35、 order number, inspection lot number(s), AMS 4174D, size, and quantity. The report shall also identify the producer, the product form, and the size of the mill product. 4.5 Resampling and Retesting: Shall be in accordance with AMS 2355. 5. PREPARATION FOR DELIVERY: 5.1 Identification: Shall be as ag
36、reed upon by purchaser and vendor. 5.2 Packaging: Rings shall be prepared for shipment in accordance with ASTM B 660 and in compliance with applicable rules and regulations pertaining to the handling, packaging, and transportation of the rings to ensure carrier acceptance and safe delivery.

NOTES: 8.1 A change bar (|) located in the left margin is for the convenience of the user in locating areas where technical revisions, not edito
39、rial changes, have been made to the previous issue of a specification. An (R) symbol to the left of the document title indicates a complete revision of the specification, including technical revision. Change bars and (R) are not used in original publications, nor in specifications that contain edito
40、rial changes only. 8.2 Hardness of Solution and Precipitation Heat Treated Rings: 8.2.1 Hardness should be 125 HB/10/500 or 130 HB/10/1000. Hardness has been used to verify that rings have been properly processed, but an out-of-range hardness number is not always indicative of rings with out-of-spec
