Duplex Stainless Steel Pipe and Tube

Duplex stainless steel presents a  microstructure with a roughly 50/50 ratio of ferritic/austenitic stainless steels. Duplex grades offer excellent resistance to corrosion with twice the design strength of austenitic and ferritic stainless steels. Thanks to their slightly lower nickel content, Duplex alloy grades are often a cost-effective alternative to nickel alloys, even in the most demanding of applications.
