Why not ask the vendor about the difference? Maybe stellite would be better for the application than SS316? What does the as yet unmentioned duty actually require?

Stellite should be a better alloy than SS316 in the respect of
corrosion and wear resistance. Solid Stellite has proven its application as a
better material for engine valve service. The service expectation of engine
valve should be more severe than the plate in a check valve.

Solid Stellite will be a better option than SS 316 . No doubt in that . The main thing is why is vendor offering such high grade when SS 316 has been selected in the VDS ( vms ) . Could u specify the sservice please. it seems to be intresting. Is the Valve swing type?...
Stellite is the most expensive, but worth the money if you have a very corrosive or erosive environment, like superheated steam or exhaust that must be throttled.For normal service,a cheaper SS may be used.
