Duplex Alloys belong to stainless steel category where a two phase mixed microstructure is their main characteristic. The proportion of both austenite and ferrite in the ALLOY 1.4362 lean duplex (austenitic-ferritic) stainless steel is almost always in an equal ratio. Amongst duplex alloys, grade 2304 is stainless steel that has a composition of about 23% chromium with around 4% nickel. Since the content of molybdenum in the alloy is trivial, manufacturers refer to this alloy as a molybdenum-free duplex grade. Because the composition of Alloy 2304 Lean Duplex Products is similar to that of grade316L, the corrosion resistance properties of both the alloys tend to be similar.

Furthermore, the mechanical properties of lean duplex stainless steel s32304 are almost two times that of both austenitic grades, i.e. alloy 304L as well as alloy 316L. The higher mechanical property is what permits the designer, to save weight, especially if he is designing vessels for high pressure applications. The SAF 2304® lean duplex material is considered to be suitable for those tasks which are involved between temperature ranges of  -50 °C to +300 °C. Lean duplex grades have moderate resistance to pitting, which is attributed to a PREN value ranging between 22 – 27.

Typically EDX /LDX 2304 Stainless Steel, was ideated more latterly for less imperious utilisation, expressly in industries reloving both building and construction. though the corrosion resistance properties of EDX 2304 Duplex stainless tend to be similar to that of grade 316L, the benefit of using them is their resistance to stress related corrosion cracking as well as a higher boost to their mechanical properties. A combination of the aforementioned properties can be a great asset to businesses when strength is an important factor, say for e.g., the use of lean duplex UNS S32304 in the construction of bridges, pressure vessels or even tie bars.
