1: Product Details
Duplex 2304 is a 23% chromium, 4% nickel, molybdenum-free duplex stainless steel whose structure is a balance of
ferritic and austenitic. It has general corrosion resistance similar or better than Alloys 304L and 316L but with yield strength
nearly double that of austenitic stainless steels. Its duplex microstructure and low nickel and high chromium contents also
allows Duplex 2304 to demonstrate improved stress corrosion resistant properties compared to 304 and 316. It is typically
suitable for all applications in the -58oF to 572oF (-50oC to 300oC) temperature range and is designed to feature high
mechanical strength, good weldability, good corrosion resistance, high resistance to stress corrosion cracking, good
machinability, low thermal expansion, good fatigue properties, high thermal conductivity, and easy fabrication.
Applications:
Duplex 2304 is generally used in the same applications in which Alloys 304 and 316L are used.

*Propeller and pump shafts for seawater service
*Plants for uranium and isotope separation in the production of nuclear fuel
*Pumps and valves used in the manufacture of chlorinated hydrocarbons
*Monoethanolamine (MEA) reboiler tubes
Corrosion Resistance:
*Due to its high chromium content of 23%,the corrosion resistance properties are practically equivalent to those of Alloy 316L
*Its duplex microstructure and low nickel and high chromium contents allows Duplex 2304 to have improved stress corrosion
resistance properties compared to the 304L and 316L standard austenitic grades.
*More resistant to pitting and crevice corrosion resistance that Alloy 316L
*Outperforms Alloys 304L and 316L in stress corrosion cracking resistance in chloride containing aqueous
solutions:
*Its corrosion rate in boiling nitric acid (65%) is higher than that of Alloy 316L
*Its high yield strength allows Duplex 2304 to perform well in abrasion/corrosion applications
Structure:
*Microstructure of Duplex 2304 is very stable compared to molybdenum containing duplex stainless steels
*Contains approximately equal amounts of ferritic and austenitic in microstructure after annealing in a temperature about.
