1.What is G30 material?
G30 material usually refers to Hastelloy G30, which is a nickel - based high - temperature alloy.The following is a detailed introduction:
2.What is the meaning of G30?
In the context of materials, G30 generally represents Hastelloy G30. It is designated as UNS N06030 or DIN 2.4603.
Besides, G30 may also have other meanings in different fields, such as "Group of 30" in the economic and financial field, which is an informal organization composed of 30 central bankers, thinkers, practitioners, and academics worldwide
3.What is the composition of Hastelloy G30?
It is mainly composed of nickel (Ni) as the matrix, with a chromium (Cr) content of 28.0 - 31.5%, a molybdenum (Mo) content of 4.0 - 6.0%, and an iron (Fe) content of 13.0 - 17.0%. It also contains a small amount of copper (Cu, 1.0 - 2.4%), tungsten (W, 1.5 - 4.0%), cobalt (Co, ≤5.0%), and trace elements such as silicon (Si, ≤0.8%), manganese (Mn, ≤1.5%), carbon (C, ≤0.03%), niobium plus tantalum (Cb + Ta, 0.3 - 1.5%), phosphorus (P, ≤0.04%), and sulfur (S, ≤0.02%).




4.What is the difference between Hastelloy G30 and C276?
Corrosion - resistance characteristics: G30 has excellent corrosion resistance in phosphoric acid environments and is also resistant to pitting, crevice corrosion, and stress corrosion cracking in chloride environments. It can also be used in sulfuric acid, hydrochloric acid, and hydrofluoric acid environments. C276 has excellent corrosion resistance in both oxidizing and reducing environments, and is particularly good at resisting pitting, crevice corrosion, and stress corrosion cracking. It is one of the few materials that can resist the corrosion of wet chlorine, hypochlorite, and chlorine dioxide solutions, and also has significant corrosion resistance to high - concentration chloride solutions.
Application scenarios: G30 is mainly used in phosphoric acid, sulfuric acid, and nitric acid processing industries, as well as nuclear fuel reprocessing, nuclear waste treatment, pickling operations, petrochemical products, fertilizer production, and other fields. C276 is widely used in chemical processing, oil and gas industries, paper pulp and paper - making industry, FGD systems, and equipment and components operating in acidic gas environments.
Temperature resistance: C276 can be used in high - temperature environments of up to 1900°F, while G30 can be used in high - temperature environments of up to 1800°F.
Range of resistant media: C276 has a wider range of resistance to inorganic and organic chemicals than G30.
