S3555j2W yog cov huab cua qis-zog, cov tuam tsev thiab lwm yam kev ua haujlwm zoo thiab kev ua haujlwm zoo thiab ua haujlwm zoo thiab ua haujlwm zoo. lub neej thiab kev saib xyuas tsawg nyob rau hauv cov chaw hnyav ib puag ncig.
1.}} kev siv tshuaj lom neeg thiab alloy tsim
Cov tshuaj lom neeg muaj pes tsawg leeg ntawm S3555j2W yog nyob ntawm cov roj carbon, ua ke nrog cov chromium, tooj thiab npib chromium, tooj los ua kom muaj zog ntxiv rau theem {}}
Cov pa roj carbon (c): Cov ntsiab lus tsawg dua los yog sib npaug 0 {.}}}}}}}}
Manganese (mn): {0.45-1.60%, txhim kho kev nruj thiab ua kom tawv nqaij tsis kam, thiab txhim kho}
Chromium (CR) thiab tooj (Cu): Account rau {}}}}}} txhim kho atmospheric corrosion.
Nickel (NI) thiab Molybdenum (MO): Cov ntsiab lus tsawg dua lossis muaj sib npaug thiab tsawg dua lossis muaj kev sib luag rau cov tub rog thiab kev hloov kho kom haum rau ib puag ncig.
Phosphorus (p) thiab Sulfur (s): nruj me ntsis tswj tau tsawg dua lossis sib npaug ntawm 035%, txo qis cais cais, thiab ua kom vending zoo.
{{02. kev sib cuam tshuam ntawm cov khoom siv tshuab cov khoom siv thiab cov tuab
Cov cuab yeej ua haujlwm ntawm S355j2W qhia cov yam ntxwv gremient nrog cov kev hloov tuab, ntsib cov qauv sib txawv:
Paib lub zog: ntau dua los yog sib npaug ntawm 355 MPa thaum lub tuab yog tsawg dua los yog sib npaug rau ntawm 265 MPa thaum lub thickness nce ntxiv rau 150mm.
Tensile lub zog: {{{470-630 mpa mpa kom meej qhov ruaj khov ntawm cov khoom ruaj khov .
Elongation: ntau dua los yog sib npaug rau 22% thaum lub thickness yog tsawg dua los yog sib npaug lossis ntau dua lossis muaj zog ntxiv thiab deformation muaj peev xwm.
Kev cuam tshuam cov tawv: {{-20℃cuam tshuam lub zog loj dua los yog sib npaug rau kev ua kom tsis txhob muaj huab cua nyob hauv qhov chaw kub tsawg {}}
{{03. huab cua tiv thaiv mechanism thiab ib puag ncig zoo
Kev Tiv Thaiv Yus Tus Kheej
Thaum raug rau qhov chaw nyob ib puag ncig, tsuas yog tsim ntawm -Feooh txheej, thiab cov xim hloov pauv ntawm lub sijhawm tsaus nti, thiab cov xim roj ntsha
Cov txiaj ntsig ib puag ncig
Piv nrog tsoos galvanizing lossis txheej tiv thaiv tiv thaiv corrosion, tsis tas yuav tsum siv tshuaj lom neeg siv tshuaj, yuav tsum tau txo cov kev pa tawm; kev tsim lub neej ntev txo tau cov zaus ntawm cov khoom hloov, uas yog nyob rau hauv kab nrog lub tswv yim ntawm kev loj hlob ntawm kev txhim kho.
4.} cov chaw thov tseem ceeb
Txuas hniav thiab kev tsim qauv
Hla-hiav txwv txuas: siv rau cov nqaj tseem ceeb xws li cov nqaj tseem ceeb thiab cov piers, tiv taus cov kev tsim lub neej ntau dua 100 xyoo.
High-res vaj tse: raws li kab hlau rhuav phab ntsa txhawb nqa thiab ru tsev qauv thaum txhim kho cua thiab av qeeg tsis kam.
Lub nkoj nkoj thiab cov khoom siv marine engineering
Hull lawj: Dej hiav txwv corrosion txuas ntxiv mus txuas ntxiv rau kev kho lub voj voog thiab txo cov kev ua haujlwm ntawm cov nkoj dej hiav txwv.
Offshore Platforms: siv rau cov yeeb nkab thav duab thiab cov pawg ua hauv pawg kom tiv thaiv tidal cuam tshuam thiab microbial txuas .
Lub Zog thiab Kev Siv Kev Tiv Thaiv Kev Tiv Thaiv
Cua Fais Fab Ntauwd: Haum rau cov ntsev ntau POB ZEB
Dej phwj tank: withstand acid thiab alkali nruab nrab kev yaig thiab txo qhov xav tau kev tu ntawm kev tiv thaiv corrosion.
Cov Khoom Siv Tsheb Thauj Mus Los
Freight Thawv: Kev tiv thaiv tus kheej ntawm sab xeb txheej, hloov mus rau ib puag ncig huab cua thoob ntiaj teb.
Railway lub tsheb ncej: Siab zog thiab nkees ua kom muaj kev ruaj ntseg siab kev nyab xeeb {}}
