5、eding AMS2259E Chemical Check Analysis Limits Wrought Low-Alloy and Carbon Steels RATIONALE AMS2259F results from a Five-Year Review and update of this document that corrects the upper manganese limit in Table 3. 1. SCOPE 1.1 Purpose This specification defines limits of variation for determining acc
6、eptability of the composition of wrought low-alloy and carbon steel parts and material acquired from a producer. 1.1.1 Check analysis limits for elements or for ranges of elements not listed herein shall be as specified in the applicable material specification or as agreed upon by purchaser and prod
7、ucer. 1.2 Application When specifically referenced in the material specification, the purchaser may apply check analysis limits to determine the acceptability of parts and materials at purchasers final acceptance test or verification test operation. Use of check analysis limits is not permitted for
8、ladle or ingot analyses, or for other acceptance testing by the producer. 2. APPLICABLE DOCUMENTS The issue of the following documents in effect on the date of the purchase order forms a part of this specification to the extent specified herein. The supplier may work to a subsequent revision of a do
9、cument unless a specific document issue is specified. When the referenced document has been cancelled and no superseding document has been specified, the last published issue of that document shall apply. 2.1 SAE Publications Available from SAE International, 400 Commonwealth Drive, Warrendale, PA 1

TECHNICAL REQUIREMENTS 3.1 Analytical Procedures Referee analysis shall be by any method acceptable to purchaser and producer. 3.2 Definitions 3.2.1
12、 Check (Product or Verification) Analysis Analysis made by purchaser of parts or materials to verify the composition of a heat or lot or to determine variations in the composition within a heat or lot. Acceptance or rejection of a heat or lot of material or batch of parts may be made by applying var
13、iation limits as described in 3.2.2. In the analysis of finished parts, limits do not apply to elements whose percentage can be varied by fabricating techniques employed (for example carbon in steel) unless the sample is taken in such a manner as to exclude such variations. 3.2.2 Variation Limit, Un
14、der Minimum or Over Maximum Given in 3.3 is the amount an individual determination for a specified element may vary under or over the specified composition limit. In no case shall the reported determinations of any element (except lead) in a heat, using the same analytical procedure, vary both above
15、 and below the specified range. Lead may vary both above and below the specified range. Dimensional sizes shown in paragraph titles or text or in column headings refer to the cross-sectional area of the product being analyzed. 3.2.3 Remainder Shows the basis element from which the alloy is made and
16、is assumed to be present in an amount approximately equal to the difference between 100% and the sum percentage of the alloying elements and listed impurities. Analysis for and reporting of the basis element are not required. 3.2.4 Residual Elements, Each, Maximum The maximum amount of an individual
17、 element not mentioned specifically in the specified composition that may be present. Producer normally will analyze only for elements which are possible to be present because of raw materials or manufacturing processes and which may affect the product significantly. Others will analyze for impuriti
18、es as they deem necessary. 3.2.5 Residual Elements, Total, Maximum The sum percentage of the residual elements (see 3.2.4) found. It shall not be concluded from this statement that an analysis need be made for each element of the periodic table not mentioned specifically in the composition section.
19、3.3 Check Analysis Variation Limits 3.3.1 Carbon Steels Variations for carbon, phosphorus, and sulfur do not apply to rimmed or capped steels. Variations for phosphorous and sulfur do not apply to rephosphorized or resulfurized steels. Boron is not subject to check analysis variation limits. SAE INT

Sample material shall be free from scale, grease, dirt, and other foreign materials, and shall be taken in such a manner as to prevent alteration of the ch
47、emical composition of the sample. If finished parts are too hard for machining, they may be tempered in a protective atmosphere prior to sampling. Sampling shall be in accordance with ASTM E1806, insofar as practical. 5. PREPARATION FOR DELIVERY Not applicable. 6. ACKNOWLEDGMENT Not applicable. 7. R
