[MW:5814] Hard-facing overlay versus Corrosion resistent overlay

Dear All,

 

According to ASME IX the difference between Hard-facing overlay and Corrosion resistant overlay is limited to the type of tests that is required on PQR and WPS ?

 

According to ASME, how to define if certain overlay is a Corrosion resistant or a Hard-face?

 

Thanks
