Characteristics of Hastelloy G30
Hastelloy G-30 is a nickel-based alloy with high chromium content. It has better corrosion resistance than most other nickel-based and iron-based alloys in the mixed environment of phosphoric acid and phosphoric acid and many highly oxidizing acid media, such as nitric acid/hydrochloric acid, nitric acid/hydrofluoric acid and sulfuric acid.G-30 alloy can prevent the formation of grain boundary precipitation in the welding heat affected zone, so its as-welded products are suitable for various chemical treatment engineering applications.
Typical applications of Hastelloy G30
Hastelloy G-30 is commonly used in phosphoric acid, sulfuric acid and nitric acid equipment; Reprocessing of nuclear fuel; Nuclear waste disposal; Pickling operation; Petrochemical products; Chemical fertilizer production; Pesticides; Gold extraction and other fields.
