Re: [MW:5815] Hard-facing overlay versus Corrosion resistent overlay

Hi,
 
corrosion resistant overlay applying to prevent corrosion of equipment when corrosive chemical service.
hard facing overlay applying to prevent wear when contact with another metal. eg. bearings, wear plate.

Thanks & Regards

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
