Chemical Composition6.1 Chemical AnalysisSamples for chemical analysis and method of analysis shall be in accordance with Test Methods,Practices, and Terminology A751.6.2 Heat AnalysisAn analysis of each
43、 heat of steel shall be made by the steel manufacturer to determine the percentages ofthe specified elements. If secondary melting processes are employed, the heat analysis shall be obtained from one remelted ingotor the product of one remelted ingot of each primary melt. The chemical composition th
44、us determined, or that determined froma product analysis made by the tubular product manufacturer shall conform to the requirements specified.6.2.1 For steels ordered under product specifications referencing this specification of general requirements, the steel shall notcontain an unspecified elemen
45、t, other than nitrogen for stainless steels, for the ordered grade to the extent that the steel conformsto the requirements of another grade for which that element is a specified element having a required minimum content.
