A number in parentheses indicates the year of last reapproval. This standard has been approved for use by agencies of the Department of Defense.

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. Current edition approved May 1, Originally approved in The last approved version of this historical standard ast referenced on www. When master heats are used to prepare melts, a melt analysis shall 4a94 reported. General Conditions for Delivery 4.

Fe Ni Cr 3. Order M or M30C when weldability is required. Element to be analyzed and reported for information only. Furnace or air cool to room temperature. It may be subsequently age hardened to the hardness specified in Table 3 and finished machined or ground.

B For cross sections over 6 in. NOTE 1—Proper heat treatment of these alloys is usually aetm to enhance corrosion resistance and, in some cases, to meet mechanical properties. Minimum heat-treat temperatures are specified; however, it is sometimes necessary to a4494 treat at higher temperatures, hold for some minimum time at temperature, and then rapidly cool the castings atm order to enhance the corrosion resistance and meet mechanical properties.

When Class 3 is specified, grade M25S shall be supplied in the age-hardened condition.

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 alloy families are: Chemical composition shall be reported to the purchaser or his representative.

Test results shall conform to the tensile sstm specified in Table 3.

Nickel-Copper

Test bars shall be poured in special blocks from the same heat as the castings represented. If the castings are not heat treated, the bar used for the test specimen must not be heat treated.

B 65 [] B HB minimum for the age hardened condition. Workmanship, Finish, and Appearance 9. Cleaning may be accomplished by blasting with clean sand or metallic corrosionresistant shot or by other approved methods. However, the chills, chaplets and affected cast astmm must be completely removed.

Repair by Welding The composition of deposited weld metal shall be similar to that of the castings. All atm weld repairs shall be considered minor. Major and minor weld repairs aatm be subject to the same quality standards as are used to inspect the castings. If post-weld heat treatment is required, it must be specified along with the grade.

If required, it shall be performed in accordance with Section 6. Rejection and Rehearing In case of dissatisfaction with the results of the tests, the manufacturer may make claim for a rehearing within that time. To minimize small defects caused by dislodged particles of molding sand, the number of cast identification marks shall be minimized.

The marking of heat numbers on individual castings shall be agreed upon by the manufacturer and the purchaser. Markings shall be in such position as not to injure the usefulness of the casting. Liquid Penetrant Examination S6. The test location, number of tests, and hardness values shall be agreed upon between the manufacturer and purchaser. Hardness determinations shall be made on two different representative areas of each casting or coupon.

The weld test to be used shall be agreed upon between the purchaser and manufacturer. The presence of cracks shall be cause for rejection. The lot represented by the test specimen shall be accepted if it complies with the following crack requirements: This specimen may be the same one to be used for the bend specimen.

Cracks originating at the weld bead undercuts, at weld slag inclusions, or at casting defects shall not be cause for rejection. Approved May 1, ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard.

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.
