G-30® Alloy
UNS N06030
Trade Name: Hastelloy®
HASTELLOY® G-30® alloy is a high chromium nickel-base alloy which shows superior corrosion resistance over most other nickel- and iron-base alloys in commercial phosphoric acids as well as many complex environments containing highly oxidizing acids such as nitric/hydrochloric, nitric/hydrofluoric and sulfuric acids.
The resistance of G-30 alloy to the formation of grain boundary precipitates in the heat-affected zone makes it suitable for use in most chemical process applications in the as-welded condition. (Information provided by Haynes International, Inc.)
