Duplex stainless steel tubes are a unique category of stainless steel that combine the properties of both austenitic and ferritic stainless steels. This special composition allows duplex stainless steel to exhibit higher strength, improved corrosion resistance, and enhanced durability compared to traditional stainless steel grades. The term "duplex" refers to the dual-phase microstructure of these alloys, which consists of approximately equal parts of ferrite and austenite.
