However, the chills, chaplets and affected cast material must be completely removed. Asttm chemical composition requirements of the alloys are presented. This specimen may be the same one to be used for the bend specimen. Markings shall be in such position as not to injure the usefulness of the casting.
The composition of deposited weld metal shall be similar to that of the castings. The awtm property requirements including the heat treatment procedure for the castings are presented in detail.
Rejection and Rehearing If required, it shall be performed in accordance with Section 6.
Cast Grade: CY40
Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. It is required that one tension test shall be made from each master heat except for grades M25S and CY5SnBiM when the master heat is used to pour the castings. Test results shall conform to the specified tensile requirements.
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.
B For cross sections over 6 in. Approved May 1, B 65  If the castings are not heat treated, the bar used for the test specimen must not be heat treated. Element to be analyzed and reported for information only. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application.

To minimize small defects caused by dislodged particles of molding sand, the number of cast identification marks shall be minimized. Asym may be accomplished by blasting with clean sand or metallic corrosionresistant shot or by other approved methods.

It may be subsequently age hardened to the atsm specified in Table 3 and finished machined or ground. This standard has been approved for use by agencies of the Department of Defense.
When Class 3 is specified, astmm M25S shall be supplied in the age-hardened condition. The presence of cracks shall be cause for rejection. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
General Conditions for Delivery 4. The test location, number of tests, and hardness values shall be agreed upon between awtm manufacturer and purchaser. ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard. If post-weld heat treatment is required, qstm must be specified along with the grade. Test results shall conform to the tensile requirements specified in Table 3.
The producer shall report for information all elements in Table 1 for which a limit is given for any alloy in the same alloy family. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.
Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. B HB minimum for the age hardened condition.
The lot represented by the test specimen shall be accepted if it complies with the following crack requirements:
