Standard Specification for Steel Forgings, General Requirements
|Publication Date:||1 March 2018|
|ICS Code (Iron and steel forgings):||77.140.85|
This specification2 covers a group of common requirements that, unless otherwise specified in the individual product specification, shall apply to steel forgings under any of the following specifications issued by ASTM:
A1021/A1021M Martensitic Stainless Steel Forgings and Forging Stock for High-Temperature Service
A1049/A1049M Stainless Steel Forgings, Ferritic/Austenitic (Duplex), for Pressure Vessels and Related Components
In case of conflict in requirements, the requirements of the individual product specifications shall prevail over those of this specification.
The purchaser may specify additional requirements (see 4.2.3) that do not negate any of the provisions of either this specification or of the individual product specifications. The acceptance of any such additional requirements shall be dependent on negotiations with the supplier and must be included in the order.
If, by agreement, forgings are to be supplied in a partially completed condition, that is, all of the provisions of the product specification have not been filled, then the material marking (see Section 17) and certification (see Section 16) shall reflect the extent to which the product specification requirements have been met.
As noted in the Certification Section (16), the number and year date of this specification, as well as that of the product specification, are required to be included in the product certification.
When the SI version of a product specification is required by the purchase order, Specification A788/A788M shall be used in conjunction with Test Methods A1058 instead of Test Methods and Definitions A370.
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.
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.
