    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


    Performance Table


    For a stainless steel to be labeled Duplex 2304, it must contain a number of different components including:


    • Fe Balanced
    • Cr 21.5-24.5%
    • Ni 3.0-3.5%
    • Mn 2.5% max
    • Cu .05%-2.0%
    • N .05-2.0%
    • Si 1% max

    • Pulp and paper industry (pipes, storage tanks)
    • Food industry
    • Pressure vessels
    • Mining
    • Exposure to caustic solutions and organic acids
    • Water treatment
    • Construction and architecture
