1. Introduction to Hastelloy G-30 Materials

      Hastelloy G-30 is a nickel-based high-temperature alloy composed of nickel, chromium, cobalt, tungsten and other elements, with a nickel content of about 37%. It is a high chromium content nickel-based alloy, which has excellent corrosion resistance than most other nickel-based and iron-based alloys for commercial phosphoric acid and mixed environments of many hyperoxidizing 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 welded products are suitable for various chemical treatment projects.
