Characteristics & Properties of Hastelloy C-22
Hastelloy C-22(UNS N06022) alloy is an all-around nickel-chromium-molybdenum-tungsten alloy with better overall corrosion resistance than other existing nickel-chromium-molybdenum alloys, including Hastelloy C-276, C-4 alloy and 625 alloy. Hastelloy C-22 alloy has good resistance to pitting, crevice corrosion and stress corrosion cracking. It has excellent resistance to oxidizing aqueous media, including wet chlorine, nitric acid or mixed acids containing oxidizing acids with chloride ions. At the same time, Hastelloy C-22 alloy also has ideal resistance to reducing and oxidizing environments encountered in the process. Relying on this versatile performance, it can be used in some troublesome environments or in factories with multiple production purposes. Hastelloy C-22 alloy has an exceptional resistance to various chemical environments, including strong oxidizing substances such as ferric chloride, cupric chloride, chlorine, hot contaminated solutions (organic and inorganic), formic acid, acetic acid, acetic anhydride, seawater and salt solutions. Hastelloy C-22 alloy has the ability to resist the formation of grain boundary precipitation in the heat-affected zone of welding, so that it can also be used in many chemical processes in the welded state.
Corrosion resistance
The corrosion resistance of Hastelloy C-22 is its most outstanding feature, and it is suitable for a variety of corrosive environments:
Oxidizing media: such as nitric acid, chromic acid, hypochlorite, etc.
Reducing media: such as sulfuric acid, hydrochloric acid, phosphoric acid, etc.
Local corrosion: It has strong resistance to pitting, crevice corrosion and stress corrosion cracking (SCC).
Mixed acid environment: complex media such as sulfuric acid + hydrochloric acid, nitric acid + hydrofluoric acid.
High temperature corrosion: It can still maintain good corrosion resistance at high temperatures.
Comparison with other alloys
Compared with Hastelloy C-276, C-22 has a higher chromium content and stronger oxidation resistance.
Compared with stainless steel, C-22 has significantly better pitting and crevice corrosion resistance in chloride environments.
Processing performance
Hastelloy C-22 has good processing performance, but its high strength and work hardening tendency should be noted:
Cold processing: It can be processed by cold rolling, cold drawing, etc., but attention should be paid to work hardening.
Hot working: The hot working temperature range is 950-1200°C, and overheating should be avoided.
Welding: TIG (tungsten inert gas shielded welding), MIG (metal inert gas shielded welding), plasma arc welding and other methods can be used. Heat treatment is usually not required after welding, but heat input needs to be controlled to avoid intergranular corrosion.
Application areas
Hastelloy C-22 is widely used in the following fields:
Chemical industry: used to manufacture reactors, heat exchangers, pipelines, valves and other equipment, especially in strong acid, strong alkali and mixed acid environments.
Oil and gas: used for downhole tools, valves, pumps, pipelines, etc., to resist corrosion from hydrogen sulfide, carbon dioxide and chlorides.
Environmental protection field: used for flue gas desulfurization (FGD) systems, wastewater treatment equipment, etc.
Pharmaceutical industry: used for high-purity equipment to resist corrosive media.
Nuclear industry: used for nuclear waste treatment equipment to resist corrosion from radioactive media.
