MIL-HDBK-698A

Abstract

<strong>PREFACE</strong> <br>This is one of a group of handbooks covering the metallic and nonmetallic materials used in the design and construction of military equipment, which are designated as MIL-HDBK-XXX. <br>The purpose- of these handbooks is to provide, in condensed form, technical information and data of direct usefulness to design engineers. The data, especially selected from a very large number of industrial and government publications, have been checked for suitability for use in design. Wherever practicable, the various types, classes, and grades of materials are identified with applicable government specifications authorized for use in connection with drawings; the corresponding technical society specifications and commercial designations are shown for information. <br>The numerical values for properties listed in the handbook, which duplicate specification requirements, are in agreement with the values in issues of the specifications in effect during the preparation of this handbook, Because of revisions or amendments to specifications taking place after publication, the handbook values may, in some instances, differ from those shown in current specifications. In connection with procurement, it should be understood that the governing requirements are those of the specifications of the issue listed in the contract. <br>Current issues of specifications should be determined by consulting the latest issue of the Department of Defense Index of Specifications and Standards (DODISS) and supplements thereto. <br>Appreciation is expressed to the American Society for Metals (ASM), the American Society for Testing and Materials (ASTM), and the Copper Development Association (CDA) for approval to use some of their data in the preparation of this handbook. <br>This revision of the handbook was prepared by the Army Materials and Mechanics Research Center.
