(Specification)Standard Specification for Pressure Vessel Plates, Heat-Treated, Carbon-Manganese-Silicon Steel
Standard Specification for Pressure Vessel Plates, Heat-Treated, Carbon-Manganese-Silicon Steel
ABSTRACT
This specification covers the standard for heat-treated carbon manganese-silicon steel plates intended for fusion welded pressure vessels and structures. The steel shall be killed and undergo normalization, quenching and tempering. Heat and product analyses shall be performed on the materials and results shall conform to the required values in chemical composition in carbon, manganese, phosphorus, sulfur, silicon, copper, nickel, chromium and molybdenum. Mechanical testing like tension test shall be done on the plates and shall conform to the required tensile strength, yield strength, and elongation.
SCOPE
1.1 This specification2 covers heat-treated carbon-manganese-silicon steel plates intended for fusion welded pressure vessels and structures.
1.2 Plates furnished under this specification are available in the following three classes:

1.3 The maximum thickness of plates is limited only by the capacity of the material to meet the specified mechanical property requirements.
1.4 The values stated in either inch-pound units or SI units are to be regarded separately 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 is to be used independently of the other without combining values in any way.
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.

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.
