Full Description
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 and health practices and determine the applicability of regulatory limitations prior to use.
