Application
Chemical plant, oil refinery, petrochemical plants, bleaching tanks for the paper industry, combustion gas desulfurisation plants, application in sea water, sulphuric and phosphoric acid. Due to the low C-content, the resistance to intergranular corrosion is also guaranteed in the welded condition.
