Standard Classification for Temper Designations for Copper and Copper Alloys Wrought and Cast 1

Transcription

1 This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because it may not be technically possible to adequetely depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version of the standard as published by ASTM is to be considered the official document. Designation: B Standard Classification for Temper Designations for Copper and Copper Alloys Wrought and Cast This standard is issued under the fixed designation B 60; 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. This standard has been approved for use by agencies of the Department of Defense. This classification is under the jurisdiction of ASTM Committee B05 on Copper and Copper Alloys and is the direct responsibility of Subcommittee B05.9 on Editorial and Publications. Current edition approved April Oct. 0, Published August 200. November Originally published as B Last previous edition B 60 99a0.. Scope *. This is a classification of temper designations for copper and copper alloys wrought and cast. The temper designations are classified by the process or processes used in manufacturing the product involved and its resulting qualities. It is not a specification of copper and copper alloy products..2 The property requirements for the tempers are given in the applicable product specification. 2. Referenced Documents 2. ASTM Standards: B 846 Terminology for Copper and Copper Alloys 2. Terminology. For terminology related to copper and copper alloys, refer to Terminology B Significance and Use 4. Significance This classification establishes an alphanumeric code of the tempers of copper and copper alloy products. 4.2 Use The alphanumeric code is used to designate product tempers in specifications and published data The letters in the code identify the type of process used to produce the product temper. For example, H indicates a temper resulting from cold working. NOTE These letters are frequently the same as those used in temper systems of other metal products. 5. Classification of Tempers 5. Annealed Tempers, O Tempers produced by annealing to meet mechanical property requirements. 5.2 Annealed Tempers, OS Tempers produced by annealing to meet standard or special grain size requirements. 5. Manufactured Tempers, M Tempers produced in the product by the primary manufacturing operations of casting and hot working and controlled by the methods employed in the operations. 5.4 Cold-Worked Tempers, H Tempers produced by controlled amounts of cold work. 5.5 Cold-Worked (Drawn), Stress-Relieved Tempers, HR Tempers produced by controlled amounts of cold work followed by stress relief Order-Strengthening Tempers, HT Tempers produced by controlled amounts of cold work followed by a thermal treatment to produce order strengthening Treated Tempers, T Tempers that are based on heat treatments followed by rapid cooling Quench-Hardened Tempers, TQ Tempers produced by quench-hardening treatments Solution -Treated Temper, TB Tempers produced by solution heat-treating precipitation hardenable or spinodal hardenable alloys Solution - Cold-Worked Tempers, TD Tempers produced by controlled amounts of cold work of solution heat-treated precipitation hardenable or spinodal hardenable alloys. 2 Annual Book of ASTM Standards, Vol *A Summary of Changes section appears at the end of this standard.

Tube, As-Welded Tempers, WM Tempers that result from forming and welding when producing tube Tube, Welded and Annealed Temper, WO Temper that results from forming, welding, and annealing when producing tube Tube, Welded and Cold-Worked Tempers, WH Tempers that result from forming, welding, and cold working when producing tube Tube, Welded, Cold-Worked and Stress-Relieved Tempers, WR Tempers that result from forming, welding, cold working, and stress relieving when producing tube Tube, Welded, and Fully Finished Tempers, O, OS, H Tempers that result from both annealing a welded and cold-worked tube, or cold working, a welded cold-worked and annealed tube. With these treatments, the weld area has been transformed into a wrought structure, and the usual temper designations apply. 6. Temper Designation Codes 6. Annealed Tempers, O: 6..

8 B SUMMARY OF CHANGES Committee B05 has identified the location of selected changes to this standard since the B 60-99a last issue (B 60-0) that may impact the use of this standard: () Document was changed from a Practice to a Classification. (2) Scope section was revised to clarify intent of the standard as a classification and not as a terminology document. () A Referenced Document section was added. (4) A Significance and Use section was added. (5) The Terminology section O2 temper designation was modified added to reference terms located in Terminology B 846, and these terms were removed 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 determination 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.
