1、Designation: A 705/A 705M 95 (Reapproved 2004)Standard Specification forAge-Hardening Stainless Steel Forgings1This standard is issued under the fixed designationA 705/A 705M; the number immediately following the designation indicates the yearof original adoption or, in the case of revision, the yea

2、r 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.1. Scope1.1 This specification2covers age-hardening stainless steelforgings for general use.1.2 The values stated in either

3、inch-pound units or SI(metric) units are to be regarded separately as standards; withinthe text and tables, the SI units are shown in brackets. Thevalues stated in each system are not exact equivalents; there-fore, each system must be used independent of the other.Combining values from the two syste

4、ms may result in noncon-formance with the specification.1.3 Unless the order specifies an “M” designation, thematerial shall be furnished to inch-pound units.NOTE 1Bar products are covered by Specification A 564/A 564M.2.

Theproducer may elect to submit an extra forging to represent eachtest lot instead of p

33、rolongations, or the test specimens can betaken from the forgings themselves.9. Number of Tests9.1 For all classes of forgings weighing from 5000 to 7000lb 2300 to 3200 kg each, at least one tension test shall bemade from each forging.9.2 For all classes of forgings weighing more than 7000 lb3200 kg

34、 each, one tension test shall be made from each endof each forging. In the case of ring forgings, the tension testspecimen shall be removed from each of two locations on theperiphery, approximately 180 apart, or insofar as practicable,from opposite ends of the forging.9.3 For forgings weighing less

35、than 5000 lb 2300 kg each,one tension test shall be made from each size classification foreach heat in each heat-treating charge. Where continuousheat-treating furnaces are used, tests shall be made on 10 % ofthe forgings of each size classification from each heat subjectedto the same heat-treatment
