C276 alloy is suitable for various chemical process industries involving oxidizing and reducing media. Its high molybdenum and chromium content enables resistance to chloride ion attack, while tungsten further enhances its corrosion resistance. C276 is one of the few materials that can withstand corrosion from moist chlorine gas, hypochlorites, and chlorine dioxide solutions. This alloy exhibits significant corrosion resistance to high concentrations of chloride salt solutions, such as ferric chloride and copper chloride.

C-276 Application Scope and Fields Include:

C276 alloy is widely used in the chemical and petrochemical industries, such as in components and catalytic systems contacting chloride-containing organic substances. This material is particularly suitable for use in high-temperature environments, mixed with impurities, and inorganic acids and organic acids (such as formic acid and acetic acid), as well as in seawater corrosion conditions.

Cold working of the C-276 alloy increases its strength. During impact testing, V-notch specimens are made from 10mm thick sheets that have been annealed. If the specimen is welded, it will exhibit some ductility within the same temperature range due to the weld seam. The impact test results for the sheets are as shown in the table below.
