Duplex Stainless Steel Flanges

Duplex Stainless steel is a variant of stainless steel in which high levels of chromium, nickel and molybdenum help improve pitting corrosion resistance. The presence of nitrogen help in structural hardening, increasing the yield strength and ultimate strength, without altering the toughness. Duplex stainless steel consists of grains of both ferritic and austenitic stainless steel. Embedded in the same material. It is generally tougher than ferritic steel and has strength almost double of that of austenitic steel. It has excellent corrosion resistance. It successfully combats inter granular corrosion. It also prevents stress corrosion cracking in chloride and sulfide environments. The term Duplex is based on the concept that they have a two phase Micro-structure consisting of grains of ferritic and austenitic stainless steel formulated in the same material. The term Super Duplex denotes high-performance Duplex steel based on elevated contents of chromium, nickel, and molybdenum to improve pitting corrosion resistance while additions of nitrogen promoted structural hardening, raising the yield strength and ultimate strength values without impairing toughness.

Duplex Stainless Steel Flanges and duplex fittings are generally lower in cost, as the lower percentage of alloying element is used in the manufacture of duplex stainless steel. The yield strength of duplex stainless steel products is higher compared to austenitic Stainless steel products, as a result of which users can purchase relatively lower thickness duplex pipes and duplex fittings. Duplex stainless steel has better ductility than ferritic steel. It cannot be hardened by heat treatment, but can be work hardened. It can also be welded easily using all the standards methods of welding. Post weld distortion and residual stresses are reduced on account of low thermal expansion. This variant of stainless steel has a wide range of applications. It is used by the chemical processing industry for transportation and storage purposes. It is also used by the oil and gas plants and offshore rigs. It is also used in the oil and gas refineries. Due to resistance to stress corrosion cracking in the presence of chloride ions, it is suitable for use in marine environments. The pulp and paper industry also uses Duplex stainless steel. Moreover, it is used in pollution control equipment.
