ASTM B247M-20

Standard Specification for Aluminum and Aluminum-Alloy Die Forgings, Hand Forgings, and Rolled Ring Forgings (Metric)

ABSTRACT
This specification covers aluminum and aluminum-alloy die forgings, hand forgings, and rolled ring forgings and includes the following UNS alloy designations: A91100, A92014, A92018, A92025, A92219, A92618, A93003, A94032, A95083, A96061, A96066, A96151, A97049, A97050, A97075, A97076, and A97175. Tempers covered by this specification includes: H112, T4, T6, T61, T73, T74, T7352, T7452, T7454, T652, T852, and H111 as well as F and 01 types. The forgings may be manufactured by pressing, hammering, or rolling, at the option of the producer. Requirements for quality assurance, chemical analysis, tension and hardness tests, heat treatment, heat-treat response, and stress corrosion resistance and stress-corrosion cracking test are detailed. The forgings shall conform to the chemical composition requirements prescribed for aluminum, silicon, iron, copper, manganese, magnesium, chromium, nickel, zinc, zirconium, and titanium. Forgings having the specified thickness shall meet the requirements specified for the mechanical properties such as tensile strength, yield strength, elongation, and Brinell hardness.
SCOPE
1.1 This specification covers aluminum-alloy (Note 1) die forgings, hand forgings, and rolled ring forgings as shown in Tables 2-4 and in Section 10 for heat-treatable alloy forgings supplied in the F and 01 tempers. The maximum thicknesses for forgings within the scope of this specification are as indicated in those tables.  
Note 1: Throughout this specification use of the term alloy in the general sense includes aluminum as well as aluminum alloy.
Note 2: For forging stock supplied as rolled or cold-finished bar or rod see Specification B211/B211M. For forging stock supplied as extruded bar or rod see Specification B221M.      
1.2 Alloy and temper designations are in accordance with ANSI H35.1/H35.1(M). The equivalent Unified Numbering System alloy designations are those of Table 1 preceded by A9, for example, A91100 for aluminum 1100 in accordance with Practice E527.  
1.3 For acceptance criteria for inclusion of new aluminum and aluminum alloys in this specification, see Annex A2.  
1.4 This specification is the SI companion to Specification B247.  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

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 adequately 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.
