What is a Duplex Steel Flanges ?

Duplex Steel Flanges are extremely corrosion resistant, work hardenable alloys. Their microstructures consist of a mixture of austenite and ferrite phases. As a result, duplex stainless steels slip-on flanges display properties characteristic of both austenitic and ferritic stainless steels. This combination of properties can mean some compromise when compared with pure austenitic and pure ferritic grades. Duplex SS Blind Flanges are in most cases, tougher than ferritic stainless steel. Strengths of duplex flanges can in some cases be double that for austenitic stainless steels.
