Hastelloy G-30 is a high chromium nickel-base alloy which has superior corrosion resistance over most other nickel and iron-base alloys in commercial phosphoric acid as well as many complex environments containing highly oxidizing acids such as nitric/hydrochloric, nitric/hydrofluoric and sulfuric acids. It resists the formation of grain boundary precipitates in the heat-affected zone, making it suitable for use in most chemical process environments in the as-welded condition. Applications: Chemical processing involving phosphoric acid, sulfuric acid and nitric acid; nuclear fuel reprocessing; nuclear waste processing; pickling operations; petrochemical; fertilizer manufacture; pesticide manufacture; and gold ore extraction.
