ASTM A268\/A268M-22<\/h3>\n

Historical Standard: Standard Specification for Seamless and Welded Ferritic and Martensitic Stainless Steel Tubing for General Service<\/h4>\n
\n

ASTM A268\/A268M<\/h4>\n

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

\n

1.1<\/span> This specification2<\/span><\/span> covers a number of grades of nominal-wall-thickness, stainless steel tubing for general corrosion-resisting and high-temperature service. Most of these grades are commonly known as the \u201cstraight-chromium\u201d types and are characterized by being ferromagnetic. Two of these grades, TP410 and UNS S 41500 (Table 1<\/span>), are amenable to hardening by heat treatment, and the high-chromium, ferritic alloys are sensitive to notch-brittleness on slow cooling to ordinary temperatures. These features should be recognized in the use of these materials.<\/p>\n

\n

1.2<\/span> An optional supplementary requirement is provided, and when desired, shall be so stated in the order.<\/p>\n<\/p><\/div>\n

\n

1.3<\/span> The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. 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. The inch-pound units shall apply unless the \u201cM\u201d designation of this specification is specified in the order.<\/p>\n<\/p><\/div>\n

\n

1.4<\/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
