Duplex stainless steel is more durable with twice as much strength & better performance index than a regular traditional stainless steel. Hence a lighter product can bring about a better performance. The alloys used to arrive at duplex quality steel renders unique feature like high resistance to pitting, cracking & corrosion to the ultimate outcome thereby making duplex steel a much favored product in the stainless steel industry. Super duplex stainless steel on the other hand, has got a greater strength & corrosion resistance index than a duplex stainless steel due to the presence of additional chromium, nitrogen and molybdenum. The same material is used while manufacturing duplex stainless steel however the usage ratio is different in both cases & change in ration results in increased strength, & corrosion resistance.
Super duplex stainless steels are best suited for some robust applications in the heavy engineering industry. For example, mining, petrochemical, engine, marine, pulp & paper industries are in need of super duplex steel for its superior quality & unique features. Every industry has its customised technique & thus product specification for super duplex or duplex stainless steel vary among industries.
