Standard Specification for Brass Rod, Bar, and Shapes 1

Transcription

1 Designation: B 2 03 Standard Specification for Brass Rod, Bar, and Shapes This standard is issued under the fixed designation B 2; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A superscript epsilon (e) indicates an editorial change since the last revision or reapproval.. Scope. This specification establishes requirements for brass rod (round, hexagonal, and octagonal), bar (rectangular and square), and shapes of UNS Alloys C2000, C200, C200, C200, C200, C20, C2000, and C20..2 Units The values stated in either inch-pound or SI units are to be regarded separately as standard. Within the text and tables, the SI units are shown in brackets. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard. 2. Referenced Documents 2.

B For rectangular bar, the Parallel Surfaces refers to thickness APPENDIXES (Nonmandatory Information) X. METRIC EQUIVALENTS X. The SI unit for strength properties now shown is in accordance with the International System of Units (SI). The derived SI unit for force is the newton (N), which is defined as that force which when applied to a body having a mass of one kilogram gives it an acceleration of one metre per second squared (N = kg m/s 2 ). The derived SI unit for pressure or stress is the newton per square metre (N/m 2 ), which has been named the pascal (Pa) by the General Conference on Weights and Measures. Since ksi = 6 4 Pa the metric equivalents are expressed as megapascal (MPa), which is the same as MN/m 2 and N/mm 2. 6

7 B2 03 X2. RATIONALE (COMMENTARY) X2. This specification is a new Standard Specification for Brass Rod, Bar, and Shapes. Federal Specification QQ-B-626, which covered a number of binary brass and leaded brass alloys in rods, shapes, forgings, and flat products, was cancelled by Rev D, Notice 2, February 2,. ASTM Specifications B 36/B 36M, B 6/B 6M, B 2/B 2M, and B 24/B 24M were referenced replacements for future procurement. X2.2 The above listed ASTM standards do not cover, in particular, UNS alloys C200 and C20 in rod and bar. As there continues to be significant commerce in these and other binary brass products, this specification for Brass Rod, Bar, and Shapes has been written by Subcommittee B0.02. X2.3 Alloys included are C2000, C200, C200, C200, C200, C20, C2000, and C20 in rod and bar sizes up to 4.0 in. in diameter, and shapes. X2.4 This specification completes the general product coverage for binary brass: B 36/B 36M for flat products; B /B M for wire; B 3 for seamless tube; B for welded tube; and this specification for rod, bar, and shapes. ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard. Users of this standard are expressly advised that deteration of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility. This standard is subject to revision at any time by the responsible technical committee and must be reviewed every five years and if not revised, either reapproved or withdrawn. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below.
