Max. Temp for plated silver

-----

Q. We do Silver Cyanide plating, and one of our customers wanted to know the maximum temperature that the silver plating could withstand. Specifically, on a gasket for sealing purposes. They currently use it up to 1250 °F with no ill effects.

A. Hi Chris
Specification AMS2410 [Techstreet affil. link] states that Silver plating on fasteners provides even lubrication up to a maximum of 1200 °F.

Similar specification AMS2411 [Techstreet affil. link] states that plated Silver prevents galling or seizing up to 1400 °F

I would assume these are approximate levels that Silver will withstand without ill effects.
Good luck,

Thanks for your help. I was having a hard time finding anything definitive.
