Material Introduction

                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.

                SuperDuplex 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.

Benefits of UNS31803 SuperDuplex Stainless Steel

                Benefits of using UNS31803 SuperDuplex stainless steel include:


  •                         Improved corrosion resistance in comparison to Duplex

  •                         Greater tensile and yield strength

  •                         Good ductility and toughness

  •                         Good stress corrosion cracking resistance (SSC)

  •                         Opportunity for purchases to reduce their material costs without compromising on quality

Applications of UNS31803 SuperDuplex Stainless Steel

                SuperDuplex is used in the oil and gas industry, on offshore platforms, in heat exchangers, chemical processing equipment pressure vessels and boilers.
