    Stainless Steel 2304

     

     

    Duplex 2304, also called Alloy 2304, is a molybdenum-free duplex stainless steel.

    It has a structure that is a balance of ferritic and austenitic and is often used as a replacement for Alloys 304L and 316L. Some of Duplex 2304 stainless steel’s other properties include:

     

    • Outstanding corrosion resistance
    • Yield strength (twice that of 304L/316L)
    • Suitable for applications covering -50ºC/+300ºC temperature range
    • Resistance to pitting and crevice corrosion
    • Improved machinability and weldability
