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.

It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

1.3 The maximum thickness of plates furnished under this specification is 4 in. [100 mm] for Class 1 and 6 in. [150 mm] for Class 2 and Class 3.
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.
