ASTM A240 / A240M:S31803 (UNRT S31803): Cov roj carbon qis, siv dav hauv cov kev siv corrosion dav dav {}}
S32205 (UNRAWT S32205): Tseem hu ua 2205 duplex, qib siab-ua tau zoo nrog kev txhim kho lub zog thiab corrosion tsis kam .
ASTM A789 / A789M: Npog seamless thiab welded tubing rau cov kev siv dav dav . qib zoo li S31803 thiab S32203 muaj nyob ntawm no.
ASTM A790 / A790M: Qhia txog cov yeeb nkab-steel-steel fresh suav nrog S32750, Super Duplex), thiab S32304 (LEAR DUPLEX) {}}
{{02.} Cov Khoom Siv Neeg Kho Tshuab DupleX Stainless Hlau
Siab Zog: Kwv yees ob zaug ntxiv rau lub zog ntawm Austenitic Stainless hlau (e {}}}}} {.
Dual microstructure: Balanced ferrite-Austenite kaujses muab kev sib xyaw ntawm lub zog thiab ductility .
3.}}}}}}}}}}}}}}} Cov Tshuaj Muaj Zog Ntawm Ob Tus Hlau Stainless
Chromium (cr): Txhim kho corrosion tsis kam .Npib tsib caug (ni): Stuffilizes Austenite thiab txhim kho Ductility .
Molybdenum (mo): Boosts tsis kam rau pitting thiab crevice corrosion .
Nitrogen (n): Nce lub zog thiab txhim kho corrosion tsis kam .
4. Daim ntawv thov ntawm cov hlau tsis muaj roj
Roj thiab Roj Kev Lag Luam:Lub sam thiaj li, cov khoom siv, thiab cov fittings (tiv taus chloride-induced kev nyuaj siab corrosion).
Offshore platforms thiab cov khoom siv tshuaj lom neeg .
Tshuaj lom neeg thiab petrochemical ua:Reactors, kev sib pauv cua sov, thiab tso tsheb hlau luam (resistions acids thiab txhoj puab ib txhis) .
Marine engineering:Marine qauv, dej hiav txwv nruab, thiab nkoj nkoj (tiv thaiv zoo heev rau dej hiav txwv corrosion) {}}}}
Daim Ntawv Thiab Picp Kev Lag Luam:Cov cuab yeej siv tau los ua cov tshuaj tiv thaiv kom dawb thiab acidic / alkaline daws .
Dej thiab Wastewater Kev Kho Mob:Twj, li qub, thiab kav dej hauv chloride ib puag ncig .
Desalination Nroj Tsuag:Cheebtsam hauv dej hiav txwv desalination tshuab .
Kev Siv Khoom Zoo thiab Tsim Tsa:High-zog cov ntawv thov hauv cov choj, vaj tse, thiab cov khoom zoo nkauj.
{{05. Cov txiaj ntsig ntawm Duplex Stainless Hlau
Zoo tshaj corrosion Kuj:Kev tiv thaiv zoo heev rau pitting, crevice corrosion, thiab kev nyuaj siab corrosion cracking (e {}}}, seawater, .
Siab lub zog thiab kev ruaj khov:Siab dua lub zog dua li Austenic qib, txo cov khoom siv tuab thiab qhov hnyav hauv cov ntawv thov txheej txheem .
Nqi-Zoo:Qis dua npib tsib xee cov ntsiab lus piv rau cov hlau ua kom qis dua, ua rau lawv muaj kev lag luam ntau rau cov kev siv high-corrosion.
Zoo Weldability:Kev tsim nyog vuam cov kev coj ua (e {{{0} g}}}}}}}}}}}}}} microsion tiv thaiv .
Yooj yim ntawm cov fabrication:Sib txuas ua ke ntawm cov qauv ntawm cov hlau tsis muaj tshuaj tiv thaiv cov hlau nrog lub zog ntawm cov qib ferritic .
Siab Thermal Thiab Siab Kuj:Haum rau kev kub-thiab cov ntawv thov kev siab siab hauv cov tshuaj thiab lub zog dectors.
Ib puag ncig tus phooj ywg:Rov qab siv dua thiab feem ntau yuav tsum tau cov khoom tsawg dua vim muaj lub zog siab, txo qhov kev cuam tshuam ib puag ncig .
