Abstract

PREFACE <br>This is one of a group of handbooks covering metallic and nonmetallic materials used in the design and construction of military equipment. <br>The purpose of this handbook is to provide, in condensed form, technical information and data of direct usefulness to design engineers. The data, especially selected from a number of government and industrial 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. The corresponding technical society specifications and commercial designations are shown for information. <br>The numerical values for properties listed in this handbook, which duplicate specification requirements, are in agreement with the values in issues of the specifications in effect at the date of this handbook. Because of revisions or amendments to specifications taking place after publication, the 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>This revision of the handbook was prepared by the Metals and Ceramics Information Center of Battelle Columbus Laboratories and the Army Materials and Mechanics Research Center. Corn. ments on this handbook are invited. They should be addressed to Director, US Army Materials and Mechanics Research Center, Watertown, Massachusetts 02172, ATTN: AM XMR.MS.
