DIN X2 Cr Ni MoN 25.7.4  is a ferritic - austenitic (duplex) stainless steel, which combined a number of ferritic steel and austenitic steel, the performance of the most useful, as the chromium and molybdenum content of steel is high, so it has a very good resistance to pitting corrosion, crevice corrosion and uniform corrosion. way to ensure that the microstructure of the steel with high resistance to stress corrosion cracking capacity, but also high mechanical strength.

DIN X2 Cr Ni MoN 25.7.4  stainless steel used in oil and gas industry; sea Dan Potian oil platform (heat exchanger tubes, water treatment and water supply systems, fire systems, sprinkler systems, steady water system; petrochemical industry equipment; desalination (desalination) equipment (and equipment in the high-pressure pipe, water pipe); both require high strength at the same time requiring high corrosion resistance of the mechanical and structural components; fuel (waste) gas purification equipment.
