what material is this? is it coated?
what material is this? is it coated?
(OP)
hello, please take a look at the attached picture.
this cap is used as a mechanical stop in lever operated ball valves (it's got no "structural" duty as it's not subject to loads)
seems clear to me that's a casting (CS or cast iron) but i'm not sure if the material is also coated in some way, or just oxidized by atmosphere?
thanks for your help
