Nickel Hastelloy Alloy G30 UNS N06030

Hastelloy G-30 resists the formation of grain boundary precipitates in the heat-affected zone, making it suitable in the as-welded condition. Hastelloy G30 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.

Composition Features of Hastelloy G30:

The composition features of Hastelloy G-30 are mainly as follows:

Nickel-based alloy: The matrix of Hastelloy G-30 is a nickel-based alloy, which is one of the main reasons for its good oxidation resistance and corrosion resistance.

Hastelloy G-30 contains a certain amount of chromium, which is one of the main reasons for its good corrosion resistance.

Hastelloy G-30 contains a moderate amount of molybdenum and tungsten elements, which add to its high-temperature strength and oxidation resistance.

Hastelloy G-30 also contains small amounts of carbon, nitrogen, silicon, magnesium, and other elements, which have a certain improvement effect on the properties of the alloy.
