Super Duplex Steel

Home / Super Duplex Steel

SuperDuplex stainless like Duplex, is a mixed microstructure of austenite and ferrite (50/50) which has improved strength over ferritic and austenitic steel grades. The main difference is that Superduplex has a higher Molybdenum and Chromium content which gives the material greater corrosion resistance.

Super Duplex has the same benefits as its counterpart – it has lower production costs when compared with similar ferritic and austenitic grades and due to the materials increased tensile and yield strength, in many cases this gives the purchaser the welcomed option of purchasing smaller thicknesses without the need to compromise on quality and performance.

Available forms are Super Duplex Steel Pipes & Tubes, Super Duplex Steel Round Bars, Super Duplex Steel Fasteners, Super Duplex Steel Sheet, Super Duplex Steel Plate, Super Duplex Steel Forged Fittings, Super Duplex Steel Valves, Super Duplex Steel pipe fittings, Super Duplex Steel flanges.
