Zoo heev tiv thaiv sulfide kev nyuaj siab corrosion cracking
Nyob rau hauv acidic roj thiab roj zoo ib puag ncig uas muaj H₂S, INCOLOY 925 nthuav tawm zoo heev tiv thaiv sulfide kev nyuaj siab corrosion cracking (SSC) thiab hydrogen embrittlement, ua tau raws li qhov yuav tsum tau ntawm NACE MR0175 / ISO 15156 rau qib siab tshaj plaws alloy npaj rau siv nyob rau hauv acidic ib puag ncig.
Ultra{0}}siab zog thiab zoo toughness
Los ntawm nag lossis daus hardening kev kho cua sov, INCOLOY 925 tuaj yeem ua tiav lub zog tawm mus txog 965 MPa lossis siab dua, thaum tuav cov ductility zoo, toughness, thiab cuam tshuam tsis kam, ua rau nws haum rau siab - load underground cov cuab yeej thiab cov khoom hauv lub taub hau.
Zoo heev tiv taus pitting thiab crevice corrosion
Chromium thiab molybdenum cov ntsiab lus endows lub alloy nrog zoo heev pitting kuj sib npaug (PREN ≈ 38) nyob rau hauv chloride - muaj ib puag ncig, ua rau nws haum rau hnyav corrosive tej yam kev mob xws li seawater, acidic brines, thiab oilfield ua dej.
Machining thiab vuam zog
Nws tuaj yeem raug ua haujlwm kub, ua haujlwm txias, thiab vuam siv cov txheej txheem sib xyaw. Nws yog qhov tsim nyog rau kev tsim cov khoom ua haujlwm- zoo li cov cuab yeej downhole, valve Cheebtsam, thiab cov kav dej.
