Super Duplex Steel

Super Duplex stainless, 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 Super Duplex has a higher molybdenum and chromium content which gives the material greater corrosion resistance than standard duplex grades. The balanced duel phase microstructure combines high strength with cost effective corrosion resistance particularly in high chloride environments. Super Duplex has the same benefits as its counterpart – it has lower alloying costs when compared with similar ferritic and austenitic grades with equipment corrosion resistance in chloride containing environments due to the material’s 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 Sheets & Plates, Super Duplex Steel Forged Fittings, Super Duplex Steel Valves, Super Duplex Steel pipe fittings, Super Duplex Steel flanges.
