  • Properties:

    Austenitic chromium-nickel-molybdenum-copper with low carbon content which resists intergranular corrosion in the temperature range up to 400° C. Possesses a very good resistance to sulphuric acid of any concentration up to about 60° C, as well as to phosphoric acid and organic acids.Excellent resistance to stress corrosion cracking, and pitting and crevice corrosion in the media containing chloride ions.

     

  • Applications:

    Applications in highly corrosive fileds where agressive chemicals are used, e.g. machines and plants cooled by seawater and offshore components. In the chemical industry where resistance to the attack of pure acids as well as acids containing chloride ions (sulphuric acid in in particular), of organic acids and mixed acids is required in the higher pressure and temperature ranges. The enhances resistance to crevice corrosion permits use also for applications where incrustation must be expected, and / or where the formation of gaps cannot be avoided by design precautions.
