    Black Finish 2304 Duplex Stainless Steel Round Bar Corrosion Resistance

    UNS ASTM Duplex 2304 Stainless Steel Round Bar Bright or Black Finish

    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.

    2. Processing

    Weldability

    Can be successfully welded by TIG manual and automatic, PLASMA, MIG, SMAW, SAW, FCAW
    Duplex microstructure renders the alloy less sensitive to hot cracking
    Pre-heating and post welding is not required
    Filler metal should be a balanced ferrite/austenitic type


    Machinability

    Exhibits improved machinability properties particularly when considering drilling
    Low speeds and high feeds will minimize this alloys tendency to work harden
