This abstract is a brief summary of the referenced standard. Combining values from the two systems may result in non-conformance with the standard. The lot represented by the test specimen shall be accepted if it complies with the following crack requirements: Fe Ni Cr 3. Current edition approved May 1, All other weld repairs shall be considered minor. Chemical composition shall be reported to the purchaser or his representative. 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.

The values stated in each system may not be x494 equivalents; therefore, each system shall be used independently of the other. This standard is subject to revision at any time by the responsible technical committee and 4a94 be reviewed every five years and if not revised, either reapproved or withdrawn.

This specification covers nickel, nickel-copper, nickel-copper-silicon, nickel-molybdenum, nickel-chromium, and nickel-molybdenum-chromium alloy castings for corrosion resistant service. The test location, number of tests, and hardness values shall be agreed upon between the manufacturer and purchaser.

It may be subsequently age hardened to the hardness specified in Table 3 and finished machined or ground. This specimen may be the same one to be used for the bend specimen. Test bars shall be poured in special blocks from the same heat as the castings represented.

Repair by Welding 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. We need your help! Order M or M30C when weldability is required. The composition of deposited weld metal shall be similar to that of the castings. If post-weld heat treatment is required, it must be specified along with the grade.

Element to be analyzed and reported for information only.
