Scope

1.1 This specification covers commercial, structural, highstrength low-alloy, and ultra-high strength steel sheet in coils and cut lengths produced by the twin-roll casting process. 1.2 The steel sheet is available in the designations listed in Section 4. 1.3 The material is available in the following sizes: Thickness: 0.027 to 0.078 in. [0.7 to 2.0 mm] Width: up to 79 in. [2000 mm] 1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. NOTE 1—A description of the Twin-roll Casting Process is included in Appendix X1. 1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
