1、Designation: B928/B928M 09Standard Specification forHigh Magnesium Aluminum-Alloy Sheet and Plate for MarineService and Similar Environments1This standard is issued under the fixed designation B928/B928M; the number immediately following the designation indicates the yearof original adoption or, in

2、the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval.A superscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope*1.1 This specification covers high magnesium (Note 1)marine application aluminum-alloy

3、(Note 2), in those alloy-tempers shown in Table 2 Table 3 and Table 4 Table 5, forflat sheet, coiled sheet, and plate, in the mill finish that areintended for marine and similar environments:NOTE 1The term high magnesium in the general sense includes thosealloys containing 3 % or more nominal magnes

4、ium.NOTE 2Throughout this specification use of the term alloy in thegeneral sense includes aluminum as well as aluminum alloy.1.2 Alloy and temper designations are in accordance withANSI H35.1/H35.1(M). The equivalent Unified NumberingSystem alloy designations are those of Table 1 preceded byA9,for

5、example, A95083 for 5083 in accordance with PracticeE527.1.3 The values stated in either SI units (Table 3 and Table 5)or inch-pound units (Table 2 and Table 4) are to be regardedseparately as standard. The values stated in each system maynot be exact equivalents; therefore, each system shall be use

6、dindependently of each other. Combining values from the twosystems may result in non-conformance with the standard.1.4 For acceptance criteria for inclusion of new aluminumand aluminum alloys in this specification, see Annex A2.1.5 This standard does not purport to address all of thesafety concerns,

7、 if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.
