The Duplex Stainless Steel Wire Mesh UNS 2304 (China Brand: 00Cr23Ni4N) is a kind of duplex stainless steel wire mesh with low alloy and developed by Swedish. Its solid solution temperature is around 1000℃. The organization is 40%-50% ferrite and 50%-60% austenite with common features of duplex stainless steel. American standard is UNS S32304 Swedish trade mark is SAF 2304.
Corrosion Resisting Property of UNS S32304 Duplex Stainless Steel Wire Mesh：
UNS S32304 super duplex’s PRE is 25 almost same with 316L stainless steel. In terms of corrosion resistance especially when the medium environment is bad( such as seawater with higher content of chloride ions) it has excellent resistance to pitting corrosion crevice corrosion stress corrosion and corrosion fatigue properties.
Alloy 2304 is a 23% chromium 4% nickel molybdenum-free duplex stainless steel. The Alloy 2304 has corrosion resistance properties similar to 316L. Furthermore its mechanical properties i.e. yield strength are twice those of 304/316 austenitic grades. This allows the designer to save weight.
The alloy is particularly suitable for applications covering the -50C/+300C (-58F/572F) temperature range. Lower temperatures may also be considered but need some restrictions particularly for filter structures.With its duplex microstructure and low nickel and high chromium contents the alloy has improved stress corrosion resistance properties compared to 304 and 316 austenitic grades.
