Super Duplex Stainless Steel

The phrase "super duplex" refers to a group of high-performance stainless steels having an alloy composition that contains about 25% chromium. The duplex family of alloys, as the name implies, has steel grains that are both austenitic and ferritic in their microstructure. The special mix of mechanical and physical qualities of Super Duplex is provided by its duplex nature.

Similar to its predecessor, Super Duplex has advantages in that it has cheaper production costs when compared to ferritic and austenitic grades of like composition. In today's petrochemical, pulp, and paper sectors, super duplex materials are frequently utilized in applications like pumps, valves, fasteners, pipelines, and connections, as well as petroleum and natural gas components.
