SAIL develops Super Duplex Stainless Steel


In a major technological breakthrough, Steel Authority of India Limited (SAIL) 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, said a press release by the company. 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, oil & gas exploration, pulp & paper industries, food processing equipment and bio fuel plants. 

Commenting on the achievement, SAIL Chairman Anil Kumar Chaudhary said, “Inspired by the Government’s clarion call for ‘Atmanirbhar Bharat’ and ‘Vocal for Local’, SAIL is relentlessly making efforts in developing steels, which can play important roles in these missions. The development of this high-end grade is an effort in that direction.”
