The alloy families are: This specification covers nickel, nickel-copper, nickel-copper-silicon, nickel-molybdenum, nickel-chromium, and nickel-molybdenum-chromium alloy castings for corrosion resistant service. If the castings are not heat treated, the bar used for the test specimen must not be heat treated. 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.

Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. Hardness determinations shall be made on two different representative areas of each casting or coupon. B HB minimum for the age hardened condition. General Conditions for Delivery 4. Please fill this form, we will try to respond as soon as possible.

The tensile property requirements including the heat treatment procedure for the castings are presented in detail. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Order M or M30C when weldability is required. The last approved version of this historical standard is referenced on www. B For cross sections over 6 in.

If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below. 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. When master heats are used to prepare melts, a melt analysis shall be reported.

The chemical composition requirements of the alloys are presented.

Markings shall be in such position as not to injure the usefulness of the casting. This standard has been approved for use by agencies of the Department of Defense. Asym minimize small defects caused by dislodged particles of molding sand, the number of cast identification marks shall be minimized.

If required, it shall be performed in accordance with Section 6.

Combining values from the two systems may result in nonconformance with the standard. 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.

We are a non-profit group that run this website to share documents. If post-weld heat treatment is required, it must be specified along with the grade. However, the chills, chaplets and affected cast material must be completely removed. Test bars shall be poured in special blocks from the same heat as the castings represented.

Cleaning may be accomplished by blasting with clean sand or metallic corrosionresistant shot or by other approved methods. In case of dissatisfaction with the results of the tests, the manufacturer may astj claim for a rehearing within that time. Work Item s – proposed revisions of this standard.

This standard is subject to revision at any time atsm the responsible technical committee and must be reviewed every five years and if not revised, either reapproved or withdrawn. Repair by Welding NOTE 1—Proper heat treatment of these alloys is usually necessary to awtm corrosion resistance and, in some cases, to meet mechanical properties.

The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Chemical composition shall be reported to the purchaser or his representative.
