High resistance to intercrystalline, stress and pitting corrosion - are the properties that describe Duplex steel. It is also capable of operating at temperatures up to 250 ℃ Due to low coefficient of thermal expansion. In contrast to ordinary austenitic acid-resistant steel grades, the described steel exhibits increased strength and resistance to abrasive wear and erosion. Its main applications include: shipbuilding, chemical, petrochemical, paper, energy and cryogenic industries. It is most often used for the production of parts and components, for example: pumps, refrigerators, screws, hollow bars, shafts, valves, aircraft components, tanks and containers intended for the transportation of chemicals (chemical tankers), desalination installations (pipelines), agitators, the arms of the rotating platforms, off-shore installations, pressure vessels, rotors and fans, press rolls, parts for machines used in the paper industry and installations in the processing and petrochemical industries, where chloride is present.
