(Specification)Standard Specification for Steel, Sheet, Cold-Rolled, Carbon, Structural, High-Strength Low-Alloy, Produced by Twin-Roll Casting Process
Standard Specification for Steel, Sheet, Cold-Rolled, Carbon, Structural, High-Strength Low-Alloy, Produced by Twin-Roll Casting Process
ABSTRACT
This specification covers cold-rolled, carbon, structural, and high-strength low-alloy, in coils and cut lengths produced by the twin-roll casting process. Cold-rolled steel sheet is available in the following designations: commercial steel, drawing steel, structural steel, and high-strength low-alloy steel. Sheet steel grades defined by this specification are suitable for welding if appropriate welding conditions are selected. For certain welding processes, if more restrictive composition limits are desirable, they shall be specified at the time of inquiry and confirmed at the time of ordering. The material shall be capable of being bent, at room temperature, in any direction through 180° flat on itself without cracking on the outside of the bent portion. Two tension tests shall be made from each heat or from each 50 tons [45,000 kg]. Yield strength shall be determined by either the 0.2 % offset method or the 0.5 % extension under load method unless otherwise specified.
SCOPE
1.1 This specification covers cold-rolled, carbon, structural, and high-strength low-alloy, in coils and cut lengths produced by the twin-roll casting process.
1.2 Cold rolled steel sheet produced by the twin-roll casting process is available in the designations as listed in 4.1.
1.3 This specification does not apply to steel strip as described in Specification A109/A109M.
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.
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.6 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.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
