SAE AMS2423F

This specification covers the engineering requirements for electrodeposition of a hard nickel and the properties of the deposit. AMS2423F is the result of a Five-Year Review and update with the addition of preplate stress relief and electrical contact locations to ordering information and 3.1.3, update wording to include application to new or overhauled parts and deleted statement regarding diffusion as it is not applicable (1.2), updated wording for stress relief treatment (3.1.1.1.3), addition of pretreatments for other basis metals (3.2.1), addition of standard wording for direct dimensional measurement of thickness (3.4.1), revision of adhesion test method to agree with that used in similar specifications (3.4.4.1), addition of ASTM B571 grind-saw test for adhesion of higher thicknesses as it is a better test (3.4.4.1), rewording of machined adhesion test to agree with that used in similar specifications (3.4.4.2), addition of hardness limit for hydrogen embrittlement to agree with similar specifications (3.4.5), change hardness from acceptance test to periodic test to agree with similar specifications (4.2.1 and 4.2.2), added standard wording for suspension of periodic testing (4.2.2.1), revision of definition of lot, moved hydrogen embrittlement test method from 3.4.5 to 4.3.3.1, updated wording for Approval (4.4), and added fixture/contact locations to control factors.
