Microstructure
Alloy 600 muaj lub ntsej muag-centered cubic qauv thiab yog ib qho ruaj khov, austenitic solid-solution alloy.
Cov cim
Kev tiv thaiv corrosion zoo rau cov xov xwm ntawm kev txo qis, oxidation thiab nitridation;
Virtual kev tiv thaiv rau chloride-ion kev nyuaj siab-corrosion tawg txawm nyob rau hauv siab kub;
Zoo heev kuj ti high-kub corrosion nyob rau hauv drychlorine thiab hydrogen chloride.
Corrosion Resistance
Cov muaj pes tsawg leeg ntawm Alloy 600 ua rau nws tiv taus ntau yam corrosives. Cov ntsiab lus chromium ntawm cov hlau ua rau nws zoo tshaj plaws rau kev lag luam ntshiab npib tsib xee nyob rau hauv oxidizing mob, thiab nws cov ntsiab lus nickel siab ua rau nws khaws cov kev tiv thaiv ntau nyob rau hauv kev txo qis. Cov ntsiab lus npib tsib xee kuj muab kev tiv thaiv zoo rau cov tshuaj alkaline.
Cov hlau muaj kev ncaj ncees tiv thaiv kom muaj zog oxidizing acid kua. Txawm li cas los xij, cov nyhuv oxidizing ntawm cov huab cua yaj ib leeg tsis txaus los ua kom tiav passivity thiab kev ywj pheej los ntawm kev tawm tsam los ntawm huab cua-saturated ntxhia acids thiab qee cov concentrated organic acids.
