Alloy 2304

Alloy 2304 - Duplex Stainless Steel

Alloy 2304 is a duplex stainless steel combining high corrosion resistance with superior mechanical strength. With a balanced structure of ferrite and austenite, it provides outstanding stress corrosion cracking resistance, making it ideal for applications in mildly to moderately aggressive environments. It serves as a cost-effective and high-performance alternative to traditional austenitic grades like 304 and 316.
