Kev piav qhia
2205
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 degree 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 degree F. 2205 yog welded nrog E2209 lossis ER2209 muab tub lim.
