Duplex stainless steels bars have enormous hardness making them the first choice for applications that need strength. Duplex stainless steels are called "duplex" because they have a two-phase microstructure consisting of grains of ferritic and austenitic stainless steel. This structure provides a unique set of benefits. Duplex steel is about twice as strong as regular austenitic or ferritic stainless steel. It is corrosion-resistant and significantly has better toughness and ductility than ferritic grades. As a top duplex stainless steel manufacturer in India, we remain extremely particular about the physical and mechanical properties of our bars.
