HFS is Hard Faced Stellite with Stellite being trademark for Co-Cr as per Note g of API 600 Table 8.
The difference between 2 offers is one is Stellited.
Anyone else?

when trim(Wedge, Seatring,...) is 13%cr+Stellite in specification, I do not know base material should be 13%cr and we must apply an overlay welding by stellite? or only base material can be A105 and two layer must be applly with 13%cr and then Stelllite after that?
please help me
