5、 2007-08 Reaffirmed 2011-10 Superseding AMS 2809 Identification Titanium and Titanium Alloy Wrought Products RATIONALE AMS 2809A results from a Five Year Review and update of this specification. 1. SCOPE This specification covers procedures for identifying wrought products of titanium and titanium a
6、lloys. 2. APPLICABLE DOCUMENTS None. 3. TECHNICAL REQUIREMENTS 3.1 Bars and Wire Shall be identified as follows: 3.1.1 Each straight bar over 0.500 inch (12.50 mm) in nominal diameter or least width of flat surface shall be marked in a row of characters recurring at intervals not greater than 3 feet
7、 (900 mm) with the material specification number and its revision letter, if any, heat number, and manufacturers identification. The characters shall be of such size as to be legible, shall be applied using a suitable marking fluid whose residue shall contain not more than traces of halogen-bearing
8、compounds, and shall be removable in hot alkaline cleaning solution without rubbing. The markings shall have no deleterious effect on the product or its performance and shall be sufficiently stable to withstand normal handling. 3.1.2 Straight bars and wire 0.500 inch (12.50 mm) and under in nominal
9、diameter or least width of flat surface shall be securely bundled and identified by a durable tag marked with the purchase order number, the material specification number and its revision letter, if any, heat number, nominal size, and manufacturers identification and attached to each bundle or shall
10、 be boxed and the box marked with the same information. 3.1.3 Coiled bars and wire shall be securely bundled and identified by a durable tag marked with the purchase order number, the material specification number and its revision letter, if any, heat number, nominal size, and manufacturers identifi
11、cation and attached to each coil or shall be boxed and the box marked with the same information. SAE AMS 2809A Page 2 of 3 3.2 Sheet, Strip, and Plate Shall be identified as follows: 3.2.1 Each sheet, strip, and plate shall be marked on one face, in the respective location indicated below, with the
12、material specification number and its revision letter, if any, heat number, manufacturers identification, and nominal thickness. The characters shall be applied using a suitable marking fluid whose residue shall contain not more than traces of halogen-bearing compounds, and shall be removable in hot
13、 alkaline cleaning solution without rubbing. The markings shall have no deleterious effect on the product or its performance and shall be sufficiently stable to withstand normal handling. 3.2.1.1 Flat strip 6 inches (150 mm) and under in width shall be marked in one or more lengthwise rows of charac
14、ters recurring at intervals not greater than 3 feet (900 mm). 3.2.1.2 Flat sheet, flat strip over 6 inches (150 mm) in width and plate shall be marked in lengthwise rows of characters recurring at intervals not greater than 3 feet (900 mm), the rows being spaced not more than 6 inches (150 mm) apart
15、 and alternately staggered. 3.2.1.3 Coiled sheet and strip shall be marked near both the outside and inside ends of the coil; the markings shall be applied as in 3.2.1 or shall appear on a durable tag or label attached to the coil and marked with the information of 3.2.1. When the product is wound o
16、n cores, the tag or label may be attached to the core. 3.3 Aircraft Tubing Shall be identified as follows: 3.3.1 Aircraft Tubing Other Than Hydraulic 3.3.1.1 Straight tubes 0.029 inch (0.75 mm) and over in wall thickness and 0.500 inch (12.50 mm) and over in nominal OD, minor axis, or least width of
17、 flat surface shall be marked in a row of characters recurring at intervals not greater than 3 feet (900 mm) with the material specification number and its revision letter, if any, heat number, manufacturers identification, and nominal wall thickness. The characters shall be of such size as to be le
18、gible, shall be applied using a suitable marking fluid whose residue shall contain not more than traces of halogen-bearing compounds, and shall be removable in hot alkaline cleaning solution without rubbing. The markings shall have no deleterious effect on the tubing or its performance and shall be
19、sufficiently stable to withstand normal handling. 3.3.1.2 Straight tubes under 0.029 inch (0.75 mm) in wall thickness or under 0.500 inch (12.50 mm) in nominal OD, minor axis, or least width of flat surface shall be securely bundled and identified by a durable tag marked with the information of 3.3.
20、1 and attached to each bundle or shall be boxed and the box marked with the same information. 3.3.1.3 Coiled tubing shall be securely bundled and identified by a durable tag marked with the purchase order number, the material specification number and its revision letter, if any, heat number, nominal
21、 OD and wall thickness, and manufacturers identification and attached to each coil or shall be boxed and the box marked with the same information. 3.3.2 Aircraft Hydraulic Tubing 3.3.2.1 Straight tubing 0.029 inch (0.75 mm) and over in wall thickness and 0.250 inch (6.25 mm) and over in OD, minor ax
22、is, or least width of flat surface shall be marked in a row of characters recurring at intervals not greater than 3 feet (900 mm) with the material specification number and its revision letter, if any, heat number, manufacturers identification, and nominal wall thickness. The characters shall be of
23、such size as to be legible, shall be applied using a suitable marking fluid whose residue shall contain not more than traces of halogen-bearing compounds, and shall be removable in hot alkaline cleaning solution without rubbing. The markings shall have no deleterious effect on the tubing or its perf
24、ormance and shall be sufficiently stable to withstand normal handling. SAE AMS 2809A Page 3 of 3 3.3.2.2 Straight tubing under 0.029 inch (0.75 mm) in wall thickness or under 0.250 inch (6.25 mm) in nominal OD, minor axis, or least width of flat surface shall be securely bundled and identified by a
25、durable tag marked with the information of 3.3.2.1 and attached to each bundle or shall be boxed and the box marked with the same information. 3.3.2.3 Coiled tubing shall be securely bundled and identified by a durable tag marked with the purchase order number, the material specification number and

30、IONS Not applicable. 5. PREPARATION FOR DELIVERY Not applicable. 6. ACKNOWLEDGMENT Not applicable. 7. REJECTIONS Product not identified in accordance with this specification or with modifications authorized by purchaser will be subject to rejection. 8. NOTES 8.1 A change bar (|) located in the left
31、margin is for the convenience of the user in locating areas where technical revisions, not editorial 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. Cha
32、nge bars and (R) are not used in original publications, nor in specifications that contain editorial changes only. 8.2 Terms used in AMS are clarified in ARP1917. 8.3 Dimensions and properties in inch/pound units and the Fahrenheit temperatures are primary; dimensions and properties in SI units and
33、the Celsius temperatures are shown as the approximate equivalents of the primary units and are presented only for information. 8.4 Similar Specifications FED-STD-184 is listed for information and shall not be construed as an acceptable alternate unless all requirements of this AMS are met.
