3. TECHNICAL REQUIREMENTS:
3.1 Composition:
Shall conform to the percentages by weight shown in Table 1, determined in accordance with
AMS 2355 or MAM 2355.
3.2Condition:
Solution heat treated, stress relieved by stretching to produce a nominal permanent set of 2% but notless than 1-1/2% nor more than 3%, and precipitation heat treated to the -T651 temper.Heat
treatment shall be performed in accordance with AMS 2772.
3.2.1 Plate shall receive no straightening operations after stretching.3.3 Properties:
Plate shall conform to the following requirements, determined in accordance with AMS 2355 orMAM 2355 on the mill produced product except as specified in 3.3.3.
3.3.1 Tensile Properties: Shall be as shown in Table 2.
3.3.3 Alternate Testing for Demonstration of Fracture Toughness: When specified, Itie producer shall guarantee that plate meets the fracture toughness requirements based on correlation of notch tensile strength/tensile yield strength (NTS/TYS) ratio, determined in accordance with 3.3.3.1 in lieu of fracture toughness testing (3.3.2). Sampling and testing requirements, and lot acceptance criteria shall be as agreed upon
3.3.3.1 Notch tensile strength shall be determined in accordance with ASTM E 338 except that specimens from plate 0.250 to 0.750 inch (6.35 to 19.05 mm). exclusive, in nominal thickness shall conform to Figure 1 of this specification and specimens from plate 0.750 inch (19.05 mm) and over in nominal thickness shall conform to Figure 2 of this specification except that, for plate 1.250 to 1.500 inches (31.75 to 38.10 mm) in nominal thickness. a 1.060 inch (26.92 mm) notched cylindrical specimen in accordance with ASTM E 602 may be used (See 8.3). Notch tensile tests shall be made in both the longitudinal and long-transverse directions, and the notch tensile strength values determined for each direction shall be divided by the tensile yield strength determined for the same direction to obtain NTS/TYS ratios. Notch tensile tests shall be conducted in both the L and LT directions on the first production lot shipped to the purchaser. Tests in the L direction shall be performed on subsequent lots, unless otherwise specified. Acceptance values for NTS/TYS shall be specified based on evidence of documented correlation between the NTS/TYS ratio and fracture toughness values (3.3.5) as demonstrated and maintained by the producer.
3.4 Quality:
Plate, as received by purchaser. shall be uniform in quality and condition, sound, and tree from
foreign materials and from imperfections detrimental to usage of the plate.
3.4.1 Each plate 0.5 inch (13 mm) and over in nominal thickness shall be ultrasonically inspected in accordance with ASTM B 594 and shall meet ultrasonic Class B.
3.5 Tolerances:
Shall conform to all applicable requirements of ANSI H35.2 or ANSI H35.2M.
4. QUALITY ASSURANCE PROVISIONS:
4.1 Responsibility for Inspection:
The vendor of plate shall supply all samples for vendo(s 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 plate conforms to specified requirements.
4.2 Classification of Tests:
4,2.1 Acceptance Tests: Composition, tensile properties (3.3.1) and fracture toughness (3.3.2) or, when specified, alternate testing for demonstration of fracture toughness (3.3.3), are acceptance tests and except for composition, shall be performed on each inspection lot.
4.2.2 Periodic Tests: When alternate testing for demonstration of fracture toughness (3.3.3) is specified, fracture toughness (3.3.2) is a periodic test and shall be performed at a frequency to maintain statistical correlation as selected by the vendor unless frequency of testing is specified by purchaser.
4.3 Sampling and Testing:
Shall be in accordance with AMS 2355 or MAM 2355, and as follows:
4.3.1 When alternate fracture toughness testing (3.3.3) is specified, sampling and testing requirements for use of notch tensile strength/tensile yield strength (NTS/TYS) ratio (3.3.3.1) must be specified.
