Hastelloy G-30 (UNS N06030 / W.Nr. 2.4603), is a highly versatile nickel-chromium-iron-molybdenum alloy known for its outstanding resistance to corrosion in a wide range of harsh environments. With its unique composition and properties, Hastelloy G30 finds extensive applications in industries such as chemical processing, petrochemicals, pollution control, and waste treatment, among others.
Hastelloy Alloy G30 is composed primarily of nickel (Ni), chromium (Cr), iron (Fe), and molybdenum (Mo), with additions of tungsten (W) and cobalt (Co) for enhanced performance. This alloy 30 offers exceptional resistance to both oxidizing and reducing acids, making it suitable for handling corrosive media such as sulfuric acid, phosphoric acid, hydrochloric acid, and nitric acid.

Key properties of Hastelloy G30 include:
HASTELLOY G-30 is an improved version of nickel-chromium-iron molybdenum-copper alloy G-3. With higher chromium, added cobalt and tungsten the nickel HASTELLOY G-30 shows superior corrosion resistance over most other nickel and iron based alloys in commercial phosphoric acids as well as complex environments containing highly oxidizing acids such as nitric/hydrochloric, nitric/hydrofluoric and sulfuric acids. Alloy G30 resists the formation of grain boundary precipitates in the heat-affected zone, making it suitable in the as-welded condition.
HASTELLOY G-30 is basically the same as other high alloys in regard to formability. It is generally stiffer than an austenitic. Because of its good ductility, cold working is relatively easy and is the preferred method of forming. The alloy is easily weldable using Gas-Tungsten Arc, Gas Metal Arc and shielded Metal Arc. The welding characteristics are similar to those of G-3.
Hastelloy G30 vs G3 vs C276 - Which One Do You Need?
Hastelloy G30 is often compared to G-3 and C-276 when selecting a corrosion-resistant nickel alloy. While G-3 offers good performance in phosphoric acid, G30 adds chromium, tungsten, and cobalt to improve resistance to oxidizing and mixed-acid environments. C-276 remains the benchmark for general chloride-induced corrosion, but G30 can outperform it in highly oxidizing acid mixtures such as nitric/hydrochloric and nitric/hydrofluoric media. For buyers in chemical processing and fertilizer plants, G30 sheet and plate are often the more economical long-life choice when oxidizing acids dominate the service conditions.
