A — 05 Standard Specification for Castings, Iron-Nickel-Chromium and Nickel Alloys, Specially Controlled for Pressure Retaining Parts for Corrosive Service1 This standard is issued under the 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. If the casting grade does not require heat treatment, the bar used for the test specimen shall not be heat treated.

If the second casting passes, then no additional radiography beyond the normal amount is re- quired. A As-cast Quench in water or rapid cool by other means as agreed upon by the manufacturer and purchaser. Dimensional tolerances should be included on the casting drawing. 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.

Originally approved in Make a transverse side the manufacturer and purchaser. Selection will depend on design and service conditions, mechanical proper- ties, and corrosion-resistant characteristics. 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.

Dimensional tolerances should be included on the casting drawing. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. If that second casting fails, all remaining castings shall be radiographed in only the rejectable areas found on the first and second castings. Within the text, the SI units are shown in brackets or parentheses.

Nondestructive examination requirements such as casting thickness shall be evaluated by visual, radiographic, and liquid penetrant inspection. All other surface features must meet the acceptance criteria class in Table 2.

Within the text, the SI units are zstm in parentheses. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.
