Take 2205 grade as an example, Cr 22%, Mo 3%, N 0.15%, its PREN value reaches 33-34, which is much higher than 304 stainless steel (PREN\u224818) and 316 stainless steel (PREN\u224824). More importantly, duplex stainless steel shows strong resistance to chloride stress corrosion cracking (SCC) – in a seawater environment containing chloride ions, ordinary austenitic stainless steel may crack within a few months, while duplex stainless steel can be used safely for decades.<\/p>\n
