Applications and Uses of Duplex Stainless Steels

Stainless steels are preferred for their superior corrosion resistance. Its derivatives are formed by altering composition of the various alloying elements. They are broadly divided into- austenitic, ferritic, martensitic, duplex and precipitation hardened stainless steels. This article will focus on the brief history, classification, properties and applications of Duplex Stainless steel.<br><br>Visit- https://www.ambicasteels.com/blog/applications-and-uses-of-duplex-stainless-steels/

  1. Duplex Stainless Steels APPLICATIONS AND USES ADVANTAGE Chemical processing, transport and storage – pressure vessels, tanks, piping, and heat exchangers Oil and gas exploration and processing equipment – piping, tubing, and heat exchangers Marine and other high chloride environments Pulp and paper industry – digesters, bleaching equipment, and stock- handling systems Cargo tanks for ships and trucks Food processing equipment Biofuels plants Higher strength permits use of thinner gauges which is useful when lighter fabrications are desired Stainless steel prices are based mainly on one particular commodity i.e. Nickel. Duplex stainless steel have relatively low Nickel content, thus making it immune to commodity price fluctuations. Both the above factors make Duplex stainless steel relatively cheaper with superior properties for specific applications.
