Alloy B-3 also withstands sulfuric, acetic, formic and phosphoric acids, and other non-oxidizing media.

C2000 flanges have better temperature capabilities in hydrofluoric, sulfuric, and diluted hydrochloric acids due to the addition of copper.

Hastelloy G-30 is an improved version of nickel-chromium-iron-molybdenum-copper alloy G-3. With higher chromium, added cobalt and tungsten, the 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. The resistance of the 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.

HASTELLOY G-30 alloy is a high-chromium nickel-based alloy that exhibits corrosion resistance superior to most other nickel- and iron-based alloys in commercial phosphoric acid and in many complex environments containing highly oxidizing acids such as nitric/hydrochloric acid, Nitric/hydrofluoric and sulfuric acid. The resistance of G-30 alloy to the formation of grain boundary precipitates in the heat affected zone makes it suitable for the as-welded condition in most chemical processing applications.

The exceptional corrosion resistance of C22 has promoted its use in many different markets wherever harsh environments are encountered, including the chemical process, pharmaceutical, food processing, oil and gas, power generation, and the paper industries.
