Hastelloy C-22 is a highly corrosion-resistant superalloy that is widely used in chemical engineering, petroleum industry and nuclear industry. Among them, Hasteloy C-22 Hastelloy is known worldwide for its excellent corrosion resistance.
Hastelloy C-22 is a nickel-molybdenum alloy that contains about 56% nickel, 13% molybdenum, 3% chromium, and 2% iron. This alloy has excellent corrosion resistance, especially against acidic media. It is resistant to a variety of non-oxidizing acids, oxidizing acids, and salt solutions, including nitric acid, sulfuric acid, phosphoric acid, chloride, and salt.
Hastelloy C-22 has excellent oxidation resistance and is able to be used stably for a long time at high temperatures. Its corrosion resistance is particularly outstanding in sulfide and chloride media, which can effectively resist corrosion and stress corrosion cracking. As a result, Hastelloy C-22 is widely used in highly corrosive environments such as chemical equipment, exhaust gas scrubbers, and nuclear reactors.
In addition, Hastaloy C-22 Hastelloy also has good weldability and machinability, which can meet the requirements of different engineering projects. It can be joined by conventional welding methods and is able to maintain its excellent corrosion resistance during the welding process. At the same time, the alloy has excellent cold working properties and can be formed by pressure processing and cold rolling.
In conclusion, Hastelloy C-22 Hastelloy plays an important role in chemical engineering, petroleum industry and nuclear industry as an excellent corrosion-resistant superalloy. It is widely favored for its excellent corrosion resistance, excellent oxidation resistance, and good weldability. Whether used in chemical plants, environmental facilities, or nuclear facilities, Hastaloy C-22 provides a reliable material solution for engineering projects.
