The heat analysis shall be obtained from one remelted ingot, or the product of one remelted ingot, from each primary melt. No comments were found for ASTM A – 11 standard test methods, practices, and terminology for chemical analysis of steel products.
Cast or Heat Analysis 5. A number in parentheses indicates the year of last reapproval.
Last previous edition approved in as A — Customer comments No comments were found for ASTM A – 11 standard atm methods, practices, and terminology for chemical analysis of steel products. This standard is subject to revision at any time by the responsible technical committee and must be reviewed every ve years and if not revised, either reapproved or withdrawn. NOTE astj recommendations should be employed to reduce the number of signicant gures, such as from It is neither practical nor necessary to specify limits for every unspecied element that might be present, despite the fact that the presence of many of these elements is often routinely determined by the producer.
See Table 1 for normal elements and ranges for stainless steels. 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. NOTE 4—All commercial metals contain small amounts of various elements in addition to those which are specied.
Several independent laboratories should be used for certication of these standards and their results statistically reviewed and merged. Normal elements and ranges for stainless steels are as follows: Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters.
NOTE 1—All of the chemical analysis procedures referenced in this document include precision statements with reproducibility data with the exception of Test Methods E The results of such analyses shall conform to the requirements specied in the material specication. If signicant variations in heat or cast size are involved, a weighted average heat or cast analysis, based on the relative quantity of metal in each heat or cast, shall be reported.
It applies only to product analysis and becomes meaningful only when the heat analysis of an element falls close to one of the specied limits. Through the new facility methane will 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. It is intended that these test methods, practices, and terminology will contain all requirements for the determination of chemical composition of steel, stainless steel, or related alloys so that product specications will need contain only special modications and exceptions.
Approved April 1, It includes both wet chemical and instrumental techniques. Current edition approved June 1, ASTM A – 11 standard test methods, practices, and terminology for chemical analysis of steel products 0. The analysis shall meet the specied limits for heat analysis.

Committee A01 has identied the location of selected changes to this standard since the last issue A — 01 that may impact the use of this standard.
Examples of denitive analytical methods include gravimetric, coulometry, titrimetric based on normality, and mass spectrometry. See Table 2 for normal elements and ranges for stainless steels.
A superscript epsilon e indicates an editorial change since the last revision or reapproval. It does not apply to cast or heat analyses determined to show conformance to specied chemical limits.
The selection of a laboratory to perform the referee analysis shall be a matter of agreement between the supplier and the purchaser. This standard w751 been approved for use by agencies of the Department of Defense. Unspecied Elements Note 4 7.
