Duplex Steel S31803 Steel Pipes supplier

Duplex Steels have a two-phase microstructure consisting of grains of ferritic and austenitic Duplex Steel. The word “duplex” denotes the two-phase microstructure of ferritic and austenitic steel grains. The ferritic and austenitic Duplex Steel grades have approximately equal proportions (i.e., 50% each) in Duplex Steel. The main difference between Stainless Steel and Duplex Steel is in composition i.e. they have a higher chromium content of 20–28% higher molybdenum, up to 5% lower nickel, up to 9% and 0.05–0.50% nitrogen content.

Duplex Steel S31803 Pipes properties

Duplex Steel S31803 Pipes are extremely corrosion resistant having high resistance to intergranular corrosion. Duplex Steel S31803 Pipes exhibit very high resistance to stress corrosion cracking even in chloride and sulphide environments. The high chromium content of Duplex Steel that protects against corrosion. At low temperatures Duplex Steel S31803 Pipes have superior ductility than the ferritic and martensitic grades and can readily be used down to at least -50 °C. Duplex Steel S31803 Pipes provides high mechanical strength and exceptional corrosion resistance properties.
