Re: [MW:31564] Re: Which is better material for Seat / Control Valves / Sour Service

SS 316 is suitable for this situation. 

SS 316  has superior resistance to corrosion for services which are corrosive for 13Cr (F6).

Dear Experts,

 

The Data sheet for Control Valve calls for Seat Material of Trim as Stellite 6 + ENP and Supplier is offering SS 316.

Whis is better - Is it Stellite 6 + ENP or SS 316?

 

Info: Service to be used is Sour Service.

Temperature : 60 Degree Centrigrade

Inlet Presure: Max. 0.5 bar g

Otlet Presure: Max. 0.3 bar g

 

Appreciate to see response ASAP.

 

Regards

VPV
