ScopeSupplementary to the he
5、at or cast analysis, a product analysis may be made on steel in thesemifinished or finished form. For definitions and methods of sampling steel for product chemical analysis,refer to SAE J408.A product analysis is a chemical analysis of the semifinished or finished steel to determine conformance to
6、thespecification requirements. The range of the specified chemical composition is normally expanded to take intoaccount deviations associated with analytical reproducibility and the heterogeneity of the steel. Individualdeterminations may vary from the specified heat or cast analysis ranges or limit
7、s to the extent shown in Tables1 through 5. The several determinations of any element in a heat or cast may not vary both above and belowthe specified range except for lead. Tables 1 through 5 provide permissible limits for various steel forms andcomposition types.Rimmed or capped steels are not sub
8、ject to product analysis limits because they are characterized by aninherently large variation in chemical composition. Also, for rephosphorized and resulfurized steels, theproduct analysis tolerance limits are not applicable for phosphorus and sulfur because of the degree to whichthese elements seg
9、regate.Boron is not subject to product analysis tolerances.2. References2.1 Applicable PublicationsThe following publications form a part of this specification to the extent specifiedherein.
