What is Super Duplex 1.4501?

Working material number 1.4501 is an improved variant of Duplex. Super Duplex is a form of stainless steel (SS) formed from an alloy (a solid solution of one or more metals in another metal) of austenite and ferrite. Normally, the ratio of the alloy between 40:60 and 50:50. Super Duplex has a number of advantages over standard stainless steel, namely:

  • It can handle a higher tensile strength handle as standard stainless steel
  • In addition, it offers better resistance to localized corrosion

Super Duplex is a form of Duplex in which the PREN value, or pitting corrosion (resistance to localized corrosion), is above 40. Although there are some alternatives with equivalent characteristics, each form of Duplex has less cost in production making its use very cost-effective.

  • Oil and gas industry;
  • Chemicals and petrochemicals;
  • Bio-industry;
  • Food industry;
  • Marine applications;
  • Water treatment and desalination plants;
  • Paper processing industry.

SUPER DUPLEX FEATURES

By choosing a suitable composition, it is possible to produce stainless steel grades produced with a structure consisting of both ferrite and austenite. This group of stainless steel grades are known as duplex stainless steels. Relative to the austenitic stainless steel grades., Duplex is characterized in particular by good mechanical properties combined with high corrosion resistance (up to a temperature of approximately 315ºC). In particular, Duplex materials are also easy to weld and machine,why they are widely used in, among others:
