2304/ S32304 duplex stainless steel plate

• Introduction of 2304/ S32304 duplex stainless steel plate:
  • UNS S32304 is a 23% chromium, 4% nickel, molybdenum-free duplex stainless steel
  • The alloy 2304 has corrosion resistance properties similar to 316L
  • Furthermore, its mechanical properties, such as yield strength, are twice those of 304L/316L austenitic grades
  • This allows the designer to save weight, particularly for properly designed pressure vessel applications
  • The alloy is particularly suitable for applications covering the -50ºC/+300ºC (-58ºF/572ºF) temperature range
  • Lower temperatures may also be considered but need some restrictions, particularly for welded structures
  • With its duplex microstructure and low nickel and high chromium contents, the alloy has improved stress corrosion resistance properties compared to 304L and 316L austenitic grades

• Applications:
  • • Generally where 304L and 316L are used
  • • Pulp and paper industry (chip storage tanks, white and black liquor tanks, digestors)
  • • Caustic solutions, organic acids (SCC resistance)
  • • Food industry
  • • Pressure vessels (weight savings)
  • • Mining (abrasion/corrosion)
