Note 3 — The committee formulating this specification has included nine grades of materials that are considered astn represent basic types of ferritic alloy steels suitable for valves, flanges, fittings, and other pressure-containing parts.
This mandatory stress relief or reheat-treatment shall be in accordance with the quali? Major repairs shall be inspected to the same quality standards that are used to inspect the castings. Heat treatments shall be performed after castings have been allowed to cool. Additional alloy steels that may better ful?
This specification covers steel castings, martensitic stainless steel and alloys steel castings for valves, flanges, fittings, and other pressure-containing parts intended aa217 for high-temperature and corrosive service.
Mandatory Postweld Heat Treatment S Examination of Weld Preparation S It is not intended to imply that these grades possess equal degrees of weldability; therefore, it is the responsibility of the purchaser to establish for himself a suitable welding technique.
V and Cb contribute to precipitation strengthening by forming? Additional alloy steels that may better fulfill certain types of service will be considered for inclusion in this specification by the committee as the need becomes apparent.
A2217 values from the two systems may result in non-conformance with the standard. Historical Version s – view previous versions of standard. Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm.

When methods involving high temperature are used in the removal of discontinuities, castings shall be preheated to at least the minimum temperatures in Table 3.
All castings with major repair welds shall be thermally stress relieved or completely reheat-treated. The grades of steels covered here are: Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility. Heat treatment shall consist of normalizing and tempering for Grade C12A and tempering for all other grades. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters.
Selection will depend on design and service conditions, mechanical properties, and the high-temperature and corrosion-resistant characteristics Note 3.

Note 3—The committee formulating this specification has included nine grades of materials that are considered to represent basic types of ferritic alloy steels suitable for valves, flanges, fittings, and other pressure-containing parts. The values stated in each system are not exact atsm therefore, each system must be used independently of the other. A superscript epsilon e indicates an editorial change since the last revision or reapproval. Since these grades possess varying degrees of suitability for high-temperature and corrosion-resistant service, it is also the responsibility of the purchaser to determine which grade shall be furnished, due consideration being given to the requirements of the applicable construction codes.
