介绍 | ATI 2304 alloy is a lean duplex stainless steel (LDSS) that contains 23% Cr, 4% Ni, and very little Mo. The corrosion resistance of ATI 2304 LDSS is similar to that of Type 316L, but its strength is much higher. The strength advantage that duplex alloys have compared to austenitic grades often allows for significant weight savings to be realized in applications where the design thickness is related to yield or tensile strength. If an alloy with similar corrosion resistance and even higher strength than ATI 2304 LDSS is desired, ATI 2102® and ATI 2003® lean duplex alloys should be considered. ATI 2304 LDSS has a duplex microstructure that consists of a nearly equal mixture of ferrite and austenite. The microstructure and composition of ATI 2304 alloy provide stress-corrosion cracking resistance that is superior to that of Types 304 or 316. |
