(Specification)Standard Specification for Steel Forgings, Austenitic, for Pressure and High Temperature Parts
Standard Specification for Steel Forgings, Austenitic, for Pressure and High Temperature Parts
ABSTRACT
This specification covers austenitic stainless steel forgings for pressure and high temperature parts such as boilers, pressure vessels, and associated equipment. The grades covered here are F304, F304H, F304L, F304N, F304LN, F309H, F310, F310H, F316, F316H, F316L, F316N, F316LN, F321, F321H, F347, F347H, F348, F348H, FXM-19, FXM-11, and F46. Materials shall be produced by melting, forging, and rough machining, and shall be furnished by heat treatment in solution treated condition (solution annealing and quenching in water, oil, or a polymer water solution). Stainless steel specimens shall undergo heat and product analyses to evaluate the conformance of individual grades to specified elemental chemical compositions. Forgings shall also be examined for the adherence of each grade to required grain sizes and mechanical properties, which include tensile strength, yield strength, elongation, and reduction of area.
SCOPE
1.1 This specification covers austenitic stainless steel forgings for boilers, pressure vessels, high temperature parts, and associated equipment.
1.2 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.
1.3 This specification includes the austenitic steel forgings that were a part of Specification A336/A336M.
1.4 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.
1.5 Unless the order specifies the applicable “M” specification designation, the material shall be furnished to the inch-pound units.
1.6 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.
1.7 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.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
