Organization: ASTM International
Publication Date: 1 March 2018
Status: active
Page Count: 9
ICS Code (Steels for pressure purposes): 77.140.30
scope:

1.1 This specification2 covers quenched and tempered vacuum-treated carbon and alloy steel forgings for pressure vessels such as those used in reactor systems. Specifically, it covers forgings for vessel closures, shells, flanges, tube sheets, rings, heads, and similar parts.

1.2 All grades are considered weldable under proper conditions. Welding technique is of fundamental importance, and it is presupposed that welding procedure and inspection will be in accordance with approved methods for the grade of material used.

1.3 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.

1.4 Unless the order specifies the applicable "M" specification designation, the material shall be furnished to the inch-pound units.

Note 1: Grades 1 and 1A are composed of different chemistries but have the same mechanical requirements.

Note 2: Designations have been changed as follows:

  Current Formerly
Grade 1 Class 1
Grade 1A Class 1A
Grade 2 Class 1 Class 2
Grade 2 Class 2 Class 2A
Grade 3 Class 1 Class 3
Grade 3 Class 2 Class 3A
Grade 4N Class 1 Class 4
Grade 4N Class 2 Class 4A
Grade 4N Class 3 Class 4B
Grade 5 Class 1 Class 5
Grade 5 Class 2 Class 5A
Grade 22 Class 3 Class 22B
Grade 22 Classes 4, 5, 6, and 7  
Grade 3V Class 3V

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.
