T – Transverse axis of specimen perpendicular to direction of grain ow during rolling or forging. D Intermediate temperatures must meet the ductility requirements of the next highest suggested hardening or aging temperature, or both. This abstract is a brief summary of the referenced standard. 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.
Time refers to minimum time material is at temperature and may be extended to obtain required ductility properties. Type and stainless steels contain a large amount of ferrite in the microstructure and can have low ductility in forgings and large diameter bars. Mechanical Properties Requirements 7.
Billets or bars for reforging may be purchased to this specification. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.

Limits are in percent maximum unless shown as a range or stated otherwise. For billets and bars for forging see Specification A NOTE 3—A typical ordering description is as follows: 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.
Types aa564, XM, and XM may be furnished in the solution-annealed or age-hardened condition. Type XM is machinable in the as-received fully heat treated condition. Combining values from the two systems may result in nonconformance with the specification. Number of Tests 8.
