Ingredient comparison
The main component of C22 alloy includes more than 50% nickel, and also contains higher elements such as chromium, molybdenum and tungsten. These components enable it to maintain strength and plasticity at high temperatures, making it suitable for high-temperature equipment.
The main components of C276 alloy include 57% nickel, 16% molybdenum, 16% chromium, 5% iron, 4% tungsten and 2.5% cobalt. These ingredients allow it to perform well in chlorine-containing environments while providing high strength and hardness.
Corrosion resistance comparison
C22 alloy has excellent corrosion resistance, especially in high-concentration chloride environments. It has good resistance to wet chlorine, nitric acid, oxidizing acids containing chloride ions, etc.
C22 alloy is more corrosion-resistant than C276 in oxidizing acids and acids containing dissolved oxygen, iron ions, liquid chlorine, etc.
C276 alloy is one of the most corrosion-resistant modern metal materials and is especially suitable for chemical process industries containing oxidizing and reducing media. It has significant corrosion resistance to moist chlorine, hypochlorite, chlorine dioxide solutions, etc., and also has good corrosion resistance to high-concentration chloride salt solutions such as ferric chloride and copper chloride.
Comparison of application scenarios
Due to its excellent corrosion resistance, C22 alloy is widely used in chemical, petrochemical and other fields, especially in environments containing high concentrations of chloride. It is suitable for manufacturing corrosion-resistant equipment, such as reactors, towers, heat exchangers, etc.
C276 alloy is widely used in chemical industry, petrochemical industry, marine engineering and other fields. Due to its excellent corrosion resistance and processability, C276 alloy performs well in a variety of oxidizing and reducing media, and is especially suitable for chlorine-containing environments.
