stelliting?
(OP)
Dear all,
what is a stellite?Is it a separate alloy material or Does stelliting mean some form of welding the base material for corrosion protection?
I would greatly appreciate any response.

The filler metal was applied using SMAW, GTAW and OAW.
I think the name is a trade name from Stoody.

I wanted a confirmation whether it is used for valve seats.Do you know exactly what type of valves and what type of seating are stellitised?
thanks once again.

By all the responses I would guess that stelliting is done where the seating has a metal to metal contact.
Now,what about the media's (say,water) temperature?Is it always high (say more than 200degrees)or perhaps there is a relation between the stellitised seat and the temparature?
Thanks to all!

Stellite gave us a lot of problems in severe conditions and high temperatures, and many manufacturers told us it was an old solution for such services, and that now they recommended other materials like Tungsten carbide or many other alloys, applied using plasma coating that gave better results. We contacted a shop who made some tests with some parts and provided much better results.
After this I moved to another job

The reason I wish to do this is to prevent corrosion of these parts. I priced out getting them nickel plated and it was $100 for that service. I do have a oxyacetylene torch and No. 6 Stellite rods. I have had these Stellite rods for twenty years but don't know how to use them.
I did some searching on the web and found that inhaling fumes from this process would be hazardous to my health and that I need to use a three times carburising flame. I don't know what a "three times carburising flame" is.
Do I need to use a flux (I don't think so)? Another concern is that I might make the parts not fit onto the grinder after I finish the application because the coating might not be thin and also not uniform.
Can I heat up a pot of stellite similar to melting lead and just dip the parts in to coat them?
My other choice is to heat up a pot of brass and coat them with that.
Thanks in advance,
Steve
