[MW:3181] Re: Weld over lay on the inner surface of an elbow

Yes , you can have the hardfacing on the inner surface with stainless steel material. But the austenitica SS are not good for erosion. For better erosion resistance you need to choose martensitic SS overlay or matensitic steel alloys

We have a problem of erosion by steam + water jet.

 

Material of the elbow is A234-WPBW Thickness: 0.75" Diameter: 28" Long Radius

 

We would like to have hard facing on the inner surface without the need for PWHT.

 

 

Can any one suggest suitable WPS for the same?
