Combining values from the two systems may result in non-conformance with the standard. Selection will depend on axtm and service conditions, mechanical properties, and corrosion-resistant characteristics.

If the casting grade does not require heat treatment, the bar used for the test specimen shall not be heat treated. Materials shall conform to specified chemical composition and tensile property requirements, and weldability qualifications.
It is a9900 responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
Make a transverse side the manufacturer and purchaser. All other surface features must meet the acceptance criteria class in Table 2.
A — 05 Standard Specification for Castings, Iron-Nickel-Chromium and Asstm Alloys, Specially Controlled for Pressure Retaining Parts for Corrosive Service1 This standard is issued under aa990 fixed designation A ; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision.
The bar shall be solution heat treated per the requirements of Table 4 in production furnaces to satm same procedure as the castings it represents. Asmt comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. All surfaces to be welded and at least 1 in. Each class imposes specific requirements for three different NDE meth- ods. This specification covers iron-nickel-chromium and nickel alloy castings specially processed with restricted melt practices, weldability testing, and nondestructive examination NDE requirements for use in pressure retaining parts with corrosive service environments.
Also includes scrapped machinery and fabricated items, chips, and turnings. Within the text, the SI units are shown in parentheses. A superscript epsilon e indicates an editorial change since the last revision or reapproval. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.
Dimensional tolerances should be included on the casting drawing. If the second casting passes, then no additional radiography beyond the normal amount is required. Current edition approved September 10, Materials shall conform to specified chemical composition and tensile property requirements, and weldability qualifications.
This standard is subject to revision at any time by the responsible technical committee and must be reviewed every? If that second casting fails, all remaining castings shall be radiographed in only the rejectable areas found on the first and second castings. Fusion disconti- manufacturer and purchaser.

If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below. Nondestructive examination requirements such as casting thickness shall be evaluated by visual, radiographic, and liquid penetrant inspection.
A number in parentheses indicates the year of last reapproval.

Selection will depend on design and service conditions, mechanical proper- ties, and corrosion-resistant characteristics. If the second casting passes, then no additional radiography beyond the normal amount is re- quired.
The distinguishing require- ments of this specification are as follows. Class D will be supplied unless otherwise specified.

Since these grades possess varying degrees of suitability for service in corrosive environments, it is the responsibility of the purchaser to determine which grade shall be furnished. Such requirements may include, but are not 9. A number in parentheses indicates the year of last reapproval. Repair by Welding
