Thank you for your suggestion .My safety valve is consolidated type 1700-S2 if you have any more information please recommend me again

Since the loading on the Valve seat in a Safety Valve is of Impact nature and Stellite is poor in withstanding Impact loads, generally Stelliting of Seats of a Safety Valve is not recommended.
