FAQ

What is super duplex stainless steel?

Super duplex refers to a group of high-performance stainless steels that contain approximately 25% chromium in their composition. Like other duplex steels, super duplex has a unique microstructure consisting of both austenitic and ferritic grains.

What grade is super duplex stainless steel?

Our super duplex stainless steel grades, including 2507, Zeron 100, Ferralium 255, Ferrinox 255, and Grade UR52N+, are highly alloyed and possess exceptional corrosion resistance that rivals high-performance austenitic grades.

What is the price of 1kg super duplex stainless steel?

The price of super duplex stainless steel is approximately Rs 500*/Kg. Contact us to know More.

What are the properties of super duplex steel?

Super Duplex is a type of stainless steel alloy that contains a combination of austenitic and ferritic microstructures, along with iron, chromium, nickel, and molybdenum. This alloy exhibits strong resistance to pitting corrosion and high tensile strength, as well as superior resistance to stress corrosion cracking at moderate temperatures compared to conventional austenitic stainless steels.
