Test results shall conform to the tensile requirements specified in Table 3. The chemical composition requirements of the alloys are presented. Test bars shall be poured in special blocks from the same heat as the castings represented.

Link to Active This link will always route wstm the current Active version of the standard.

Rejection and Rehearing If the castings are not heat treated, the bar used for the test specimen must not be heat treated. A number in parentheses indicates the year of last reapproval. In case of dissatisfaction with the results of the tests, the manufacturer may make claim for a rehearing within that time.

ASTM A / AM – 18a Standard Specification for Castings, Nickel and Nickel Alloy

Cracks originating astn the weld bead undercuts, at weld slag inclusions, or at casting defects shall not be cause for rejection.

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.


We need your help! When Class 3 is specified, grade M25S shall be supplied in the age-hardened condition. This specification covers nickel, nickel-copper, nickel-copper-silicon, nickel-molybdenum, nickel-chromium, and nickel-molybdenum-chromium alloy castings for corrosion resistant service.

ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard. We are a non-profit group that run this website to share documents. Test results shall conform to the specified a94 requirements.

Historical Version s – view previous versions of standard. When master heats are used to prepare melts, a melt analysis shall be reported.

To minimize small defects caused by dislodged particles of molding sand, the number of cast identification marks shall be minimized. Combining values from the two systems may result in nonconformance with the standard. B For cross sections over 6 in.

Approved May 1, Fe Ni Cr 3. Cleaning may be accomplished by blasting with clean sand or metallic corrosionresistant shot or by other approved methods. The castings shall be heat treated. However, the chills, chaplets and affected cast material must be completely removed. Chemical composition shall be reported to the purchaser or his representative. Furnace or air cool to room temperature.

ASTM A494 Grade CY40

Element to be analyzed and reported for information only. NOTE 1—Proper heat treatment of these alloys is usually necessary to enhance corrosion resistance and, in some cases, to meet mechanical properties.

The presence of cracks shall be cause for rejection. Permission rights to photocopy the standard may also be secured from the ASTM website www. The tensile property requirements including the heat treatment procedure for the castings are presented in detail. Liquid Penetrant Examination S6. Hardness aetm shall be made on two different representative areas of each casting or coupon.


It is informational only and not an official part of the standard; the aztm text of the standard itself must be referred to for its use and application. When Class 3 is specified, grade M25S shall be supplied in the age-hardened condition. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.

The test location, number of tests, and hardness values shall be agreed upon between the manufacturer and purchaser. Please copy and paste this embed script to where you want to embed Embed Script. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

B HB minimum for the age hardened condition. If post-weld heat treatment is required, it must be specified along x494 the grade. Major and minor weld repairs shall be subject to the same quality standards as are used to inspect the castings. Order M or M30C when weldability is required. We need your help to maintenance this website. It may be subsequently age hardened to the hardness specified in Table 3 and finished machined or ground.
