Zoo heev tiv thaiv hydrogen sulfide kev nyuaj siab corrosion cracking.
Nyob rau hauv acidic roj thiab roj zoo ib puag ncig uas muaj H₂S, INCOLOY 028 nthuav tawm zoo heev tiv thaiv sulfide kev nyuaj siab corrosion cracking (SSC), ua tau raws li qhov yuav tsum tau ntawm NACE MR0175 / ISO 15156 tus qauv rau cov khoom siv hlau siv hauv acidic ib puag ncig.
Zoo heev tiv taus pitting thiab crevice corrosion.
Lub synergistic nyhuv ntawm siab chromium, molybdenum, thiab nitrogen endows lub alloy nrog superior pitting kuj sib npaug (PREN> 40) nyob rau hauv chloride- muaj ib puag ncig, ua rau nws haum rau hnyav corrosive tej yam kev mob xws li seawater, brines, thiab acidic ntsev tov.
Zoo mechanical zog thiab workability
Nws muaj lub zog nruab nrab thiab zoo heev ductility, cia nws txias thiab kub ua haujlwm, tsim, thiab welded siv cov txheej txheem pa. Nws yog tsim rau kev tsim cov khoom sib xws xws li cov kav dej roj, cov khoom siv hluav taws xob, cov khoom siv, thiab cov kav dej.
Corrosion kuj stability nyob rau hauv ib tug dav kub ntau yam
Nws tuav ruaj khov corrosion kuj nyob rau hauv acidic media los ntawm ambient kub mus rau high kub, thiab yog tshwj xeeb tshaj yog haum rau acidic gas thiab kua ib puag ncig xws li kub tsis tshua muaj mus txog 200 degree.
