Nital Etch Inspect

CDHammis,
Can you list some of the pertinent specs? I want to make sure that the nital etch in question specifically pertains to grinding defect observation, and not any general microstructure evaluation. In general, nital is applied to steel components in order to reveal martensite. When used properly, a nital etch will differentiate ferrite, tempered martensite, and untempered martensite, which is why it is specified for observing grinding burns.
