|Publication Date:||1 March 2020|
|ICS Code (Stainless steels):||77.140.20|
This specification covers austenitic stainless steel forgings for boilers, pressure vessels, high temperature parts, and associated equipment.
Supplementary requirements are provided for use when additional testing, inspection, or processing is required. In addition, supplementary requirements from Specification A788/A788M may be specified when appropriate.
This specification includes the austenitic steel forgings that were a part of Specification A336/A336M.
The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.
Unless the order specifies the applicable "M" specification designation, the material shall be furnished to the inch-pound units.
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.
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.
