Standard for ASTM A CF8 is a cast austenitic material for pressure containing parts, which covered by ASTM A and ASTM. A standard. CF8 Chemical Requirements in those. Referenced Documents. ASTM Standards: A /A M Specification for Steel Castings, Carbon,. Suitable for Fusion Welding, for High-Temperature Ser-.

A number in parentheses indicates the year of last reapproval. This standard has been approved for use by agencies of the U. Department of Defense. Referenced Documents 1. Since these grades possess varying degrees of suitability for service at high temperatures or in corrosive environments, it is the responsibility of the downloadr to determine which grade shall be furnished. Selection will depend on design and service conditions, mechanical properties, and high-temperature or corrosion-resistant characteristics, or both. The Supplementary requirements shall apply only when specified individually by the downloadr in the download order or contract. General Conditions for Delivery 3. 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.

Method 1.

General Conditions for Delivery are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each 3.

Failure to 1. In contract specifies the applicable M specification designation case of conflict between the requirements of this specification SI units , the inch-pound units shall apply. Published June Originally Standards volume information, refer to the standards Document Summary page on approved in Failure to comply with the 7.

In case of con- chemical composition prescribed in Table 2. Combining values from the two systems may result in Figure 5 Effect of elevated temperature on static and centrifugally cast CF8 with a ferrite Seat Retainer Manual Override.

Duplex stainless steel is designed to combine improved resistance to stress corrosion cracking. If austenitic stainless steels are welded at a high temperature, carbon can combine with the chromium to form chromium carbide in the heat Page It is the joining together of four valves: top fill, bottom fill,.

Unacceptable visual surface discontinuities shall be removed and their removal verified by visual examination of the resultant cavities. Process 5. Repair by Welding Heat Treatment 6. When castings are produced with Supplementary Requirement S6 specified, weld repairs shall be inspected by liquid penetrant examination to the same standards that are used to inspect the castings.

NOTE 2—Proper heat treatment of these alloys is usually necessary to enhance corrosion resistance and in some cases to meet mechanical properties. Minimum heat-treat temperatures are specified; however, it is sometimes necessary to heat-treat at higher temperatures, hold for some minimum time at temperature, and then rapidly cool the castings in order to enhance the corrosion resistance and meet mechanical properties.

NOTE 3—When austenitic steel castings are to be used in services where they will be subject to stress corrosion, the downloadr should so indicate in his order and such castings should be solution-heat treated following all weld repairs. B Castings of these grades shall be held at the specified temperature for a minimum of 4 hours. Keywords Columbium Niobium D CD4MCu has also been removed.
