1.4462 duplex stainless steel pipes are used in pressure vessels, high pressure storage tanks, high pressure pipelines, heat exchangers (chemical processing industry), desalination and waste water treatment systems. Oil and gas pipelines, heat exchanger fittings, pulp and paper industry classifiers, bleaching equipment, storage and processing systems.
1) The corrosion resistance of the most common 2205 duplex stainless steel used in many media is better than that of ordinary 316L austenitic stainless steel, while super duplex stainless steel has extremely high corrosion resistance. In some media, such as acetic acid and formic acid It can even replace high-alloy austenitic stainless steel and even corrosion-resistant alloys.
2) It has good local corrosion resistance. Compared with austenitic stainless steel with the same alloy content, its wear resistance and corrosion fatigue resistance are better than austenitic stainless steel.
3) The coefficient of linear expansion is lower than that of austenitic stainless steel, which is close to that of carbon steel. It is suitable for connection with carbon steel and has important engineering significance, such as the production of composite plates or linings.
