Short Description:

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.

Product Description

Hastelloy G-30 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 G-30 Characteristic:

Hastelloy G-30 offers superior corrosion resistance to commercial phosphoric acid and many complex environments containing strong oxidizing acids such as nitric acid/hydrochloric acid, nitric acid/hydrofluoric acid and sulfuric acid. dIt can prevent the formation of grain boundary precipitation in the welding heat affected zone, so that it can adapt to many kinds of chemical working conditions in the welding state.
