ASTM A827/A827M-02(2007)
(Specification)Standard Specification for Plates, Carbon Steel, for Forging and Similar Applications
Standard Specification for Plates, Carbon Steel, for Forging and Similar Applications
ABSTRACT
This specification covers carbon steel plates, intended for forging, quenching-and-tempering, and similar applications in which uniformity of composition and freedom from injurious imperfections are important. Heat analysis of steel shall conform to the chemical requirements for carbon, manganese, phosphorus, sulfur, and silicon.
SCOPE
1.1 This specification covers carbon steel plates, forging quality, intended for forging, quenching-and-tempering, and similar applications in which uniformity of composition and freedom from injurious imperfections are important.
1.2 The plates are available in six grades, or chemical compositions.
1.3 When the steel is to be welded, it is presupposed that a welding procedure suitable for the grade of steel and intended use or service will be utilized. See Appendix X3 of Specification A 6/A 6M for information on weldability.
1.4 The values stated in either inch-pound or SI units are to be regarded as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values from the two systems may result in nonconformance with the specification.
