Cleaning cobalt alloys [South Africa] 

+++

Will a hot caustic cleaner etch or otherwise damage tools made of a cobalt alloy if it is used to remove cutting fluids?

Well, I guess it would depend on the particular alloy used- but all of the commercial alloys I normally think of (MP35N, Elgiloy, L-605, Stellite 6B) would laugh at hot caustic slutions. Nor would I expect hot caustic solutions to affect cemented carbides with cobalt binder.
