Due to the two phases that are present in its metallurgical structure, duplex steel, often known as duplex grades, is a type of stainless steel. Compared to other aesthetically pleasing stainless steel, this duplex steel is intended to provide superior strength and resistance against corrosion. Their primary function is to offer resistance against corrosion caused by chloride stress and chloride pitting. They contain more molybdenum and chromium than other austenitic stainless steels. The excellent performance of this duplex steel buttweld in the environment leads to the early stopping of austenitic grades. These duplex steels offer resistance to sulphide stress corrosion as well as protection against the chloride environment.
