ASTM-A1088:2019 Edition

1.1 This specification covers cold-rolled, complex phase (CP) grade, dual phase (DP) grade, and transformation induced plasticity (TRIP) grade steel sheet in coils and cut lengths.

1.2 Product furnished under this specification shall conform to the applicable requirements of the latest issue of Specification A568/A568M, unless otherwise provided herein.

1.3 The product is available in a number of designations and grades with mandatory chemical requirements and mandatory mechanical properties that are achieved through thermal or thermal-mechanical treatments, and are designed to be compatible with automotive application requirements.

1.4 The grade designation nomenclature of the product differs from other cold-rolled sheet products having mandatory mechanical properties in that ordering is to tensile, rather than yield strength values.

1.5 The text of this specification references notes and footnotes that provide explanatory material. These notes and footnotes, excluding those in tables and figures, shall not be considered as requirements of this specification.

1.6 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.7 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.

1.8 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.
