2205 yog ib tug duplex (austenitic-ferritic) stainless hlau uas muaj li ntawm 40 - 50% ferrite nyob rau hauv lub annealed mob. 2205 tau ua ib qho kev daws teeb meem rau chloride kev nyuaj siab corrosion cracking teeb meem ntsib nrog 304/304L los yog 316/316L stainless. Lub siab chromium, molybdenum thiab nitrogen cov ntsiab lus muab kev tiv thaiv corrosion zoo tshaj rau 316/316L thiab 317L stainless hauv ntau qhov chaw. 2205 tsis pom zoo rau kev ua haujlwm kub siab tshaj 600 ° F.
Lub zog tsim ntawm 2205 yog qhov siab dua 316/316L, feem ntau tso cai rau kev tsim kho phab ntsa. 2205 muaj kev cuam tshuam zoo rau qhov kub thiab txias hauv qab - 40 ° F. 2205 yog welded nrog E2209 lossis ER2209 muab tub lim.
