AMS-C-26074 Cancellation Revision C has just been issued. Titled “Electroless Nickel Coatings,” the specification covers the requirements for electroless (autocatalytic chemical reduction) deposition of nickel-phosphorous alloy coatings on metal and composite surfaces.
The document replaced MIL-C-26074 for all users except for NAVSEA Nuclear personnel. With this cancellation, users are directed to AMS-2404 for replacement purposes and AMS-2404 or AMS-2433 for new design. The table on the first page of the cancellation revision lists the correlation information to match the classes and grades of AMS-C-26074 with AMS-2404.
As we blogged about before, the AMS-C-26074 was generated to replace MIL-C-26074 and was taken directly from the source document. After the release of AMS-C-26074 Revision A, the specification was cancelled in favor of the reinstated MIL-C-26074 Revision E. The mil spec was then replaced by MIL-DTL-26074 Revision F which is a controlled distribution document for NAVSEA use only. So the AMS-C-26074 was reinstated as a replacement for the balance of users with the release of Revision B.
Since that time, AMS-2404 has been updated to resolve issues of technical equivalency. So at last the AMS-C-26074 has been put to bed!
