17、ished shape and size by hot working.5.3 When specified on the order, sample forging may be sectioned and etched to show flow lines and the condition in regardto internal imperfections. When so specified, the question of acceptable and unacceptable metal flow shall be subject to agreementbetween the
18、manufacturer and the purchaser prior to order entry.5.4 When specified on the order, the manufacturer shall submit for approval of the purchaser a sketch showing the shape of therough forging before machining, or before heat treating for mechanical properties.5.5 The grain size shall be as fine as p
19、racticable and precautions shall be taken to minimize grain growth.5.6 Material of types other than XM-9 shall be furnished in the solution-annealed condition, or in the equalized andover-tempered condition, as noted in Table 2, unless otherwise specified by the purchaser.5.6.1 Types 630, XM-16, and
20、 XM-25 may be furnished in the solution-annealed or age-hardened condition.6.

21、t Methods,Practices, and Terminology A751.7. Mechanical Properties7.1 The material, as represented by mechanical test specimens, shall conform to the mechanical property requirements specifiedin Table 2 and shall be capable of developing the properties in Table 3 when heat treated as specified in Ta
22、ble 3.7.2 The yield strength shall be determined by the offset method as described in the current edition of Test Methods andDefinitions A370. The limiting permanent offset shall be 0.2 % of the gage length of the specimen.7.3 The impact strength shall be determined at 70 to 80F 20 to 25C, by Charpy
23、 V-notch specimen Type A as described inTest Methods and Definitions A370.7.4 Material tensile tested and, when specified, impact tested in the transverse direction (perpendicular to the forging flow lines)and meeting the requirements shown in Table 3 need not be tested in the longitudinal direction

Prolongations for Tests8.1 Subject to Section 7, the forgings shall be produced with prolongat
30、ions for testing, unless otherwise specified. The producermay elect to submit an extra forging to represent each test lot instead of prolongations, or the test specimens can be taken fromthe forgings themselves.9. Number of Tests9.1 For all classes of forgings weighing from 5000 to 7000 lb 2300 to 3
31、200 kg each, at least one tension test shall be madefrom each forging.9.2 For all classes of forgings weighing more than 7000 lb 3200 kg each, one tension test shall be made from each end of eachforging. In the case of ring forgings, the tension test specimen shall be removed from each of two locati
32、ons on the periphery,approximately 180 apart, or insofar as practicable, from opposite ends of the forging.9.3 For forgings weighing less than 5000 lb 2300 kg each, one tension test shall be made from each size classification for eachheat in each heat-treating charge. Where continuous heat-treating
33、furnaces are used, tests shall be made on 10 % of the forgingsof each size classification from each heat subjected to the same heat-treatment practice.10.
