ASTM A638\/A638M-23<\/h3>\n

Redline Standard: Standard Specification for Precipitation Hardening Iron Base Superalloy Bars, Forgings, and Forging Stock for High-Temperature Service<\/h4>\n
\n

ASTM A638\/A638M<\/h4>\n

Scope<\/strong><\/p>\n

\n

1.1<\/span> This specification2<\/span><\/span> covers hot-finished or cold-finished precipitation hardening iron base superalloy bars, forgings, and forging stock for high-temperature service. The mechanical properties of these alloys are developed by suitable solution treating and precipitation hardening treatments.<\/p>\n<\/p><\/div>\n

\n

1.2<\/span> Two grades of iron base alloy are covered. Selection will depend upon design, service conditions, mechanical properties, and elevated temperature characteristics.<\/p>\n<\/p><\/div>\n

\n

1.3<\/span> The values stated in either SI units or inch-pound units are to be regarded separately as standard. SI units are shown in brackets. 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.<\/p>\n<\/p><\/div>\n

\n

1.4<\/span> Unless the order specifies an \u201cM\u201d designation, the material shall be furnished to inch-pound units.<\/p>\n<\/p><\/div>\n

\n

1.5<\/span> 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.<\/i><\/p>\n<\/p><\/div>\n
