Special Alloys > Stainless Steel Alloy 2304, Duplex 2304

Duplex 2304 aka Alloy 2304, a duplex stainless steel free of molybdenum. Its structure contains a balance of austenitic and ferritic elements. The element is often used to replace Alloys 304L and 316L.

Here are some of the properties of Duplex 2304-

  • Exceptional corrosion resistance property.
  • Yield strength consists double than 304L/316L)
  • Broad range of temperature variance for applications covering between -50ºC/+300ºC
  • Resistance to crevice corrosion and pitting
  • Enhanced machinability and weldability


  • Pressure vessels industry
  • Mining industry
  • Water treatment industry
  • Construction and architecture industry
  • Pulp and paper industry
  • Food industry

Chemical Composition-

  • Iron- In Balanced proportion
  • Chromium- Between 21.5-24.5%
  • Nickel- Between 3.0-3.5%
  • Manganese- Up to 2.5% max
  • Copper- Between .05%-2.0%
  • Nitrogen- Between .05-2.0%
  • Silicon- Up to 1% max

We proffers a broad range of sizes and forms of Duplex 2304, all of them meet the leading industry standards like ASME, EURONORM, ASTM, and DIN.
