Active Standard ASTM A541 / A541M | Developed by Subcommittee: A01.06
Book of Standards Volume: 01.05
Historical (view previous versions of standard)
This specification covers quenched and tempered carbon and alloy steel forgings for pressure vessel components. Heat and product analyses shall be performed to evaluate material conformance with chemical composition requirements. Tension and Charpy V-notch tests shall also be carried out to assess material conformance with mechanical property requirements such as, tensile strength, yield strength, elongation, reduction of area, and Charpy value. Sampling of test specimens for mechanical examination shall be done by either one of four methods specified by the purchaser. Repair welding may also be made at the option of the purchaser.
This abstract is a brief summary of the referenced standard. 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.
1.1 This specification covers requirements for quenched and tempered carbon and alloy steel forgings for pressure vessel components.
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.
Note 1—Grades 1 and 1A have different chemistries but the same mechanical requirements.
