Steel Authority of India Limited (SAIL), in a major technological breakthrough, has developed the capability to produce Super Duplex Stainless Steel in SS 32205 grade at its Salem Steel Plant (SSP).
Currently, SAIL is among the few Indian steelmakers which has developed this grade of steel. This grade of stainless steel is mainly imported so far.
The Super Duplex Stainless Steel has superior corrosion resistance with higher strength and formability. Due to these characteristics, it can be effectively used in various applications in corrosion prone areas, mainly in chemical processing equipment (transport and storage, pressure vessels, tanks, piping and heat exhaust), oil & gas exploration (process equipment, pipes, tubing, marine & other high chloride environments), pulp & paper industries (digesters and bleaching equipment), food processing equipment and biofuel plants.
