Cov qauv rau high - kub tiv taus bolts thiab cov ntawv thov ntawm ob lub stuple steel bolts

Nyob rau hauv tam sim no sivhigh - kub tiv taus bolts, cov khoom lag luam ua los ntawm cov hlwv me me 2205 tau siv dav. Duplex stainless hlau 2205 bolts muaj qhov hloov tau yooj yim thiab qis dua li 250} Kev ua haujlwm nyob ib puag ncig ntawm -60), thiab lawv tuaj yeem tiv thaiv tsawg xyoo ntawm -60 Piv txwv li, 42Crmo chromium alloy hlau bolts tuaj yeem ua haujlwm ruaj khov rau thaum lub sijhawm luv luv, tab sis lawv cov khoom siv tshuab hluav taws xob zoo li rov ua dua; Hauv kev sib piv, Duplex Stainless hlau 2205 Bolts tswj kev ua tau ruaj khov nyob rau hauv xws li ib puag ncig cov kev ib puag ncig.

Yuav ua li cas paub qhov txawv stainless hlau bolts ntawm cov khoom sib txawv ntawm cov khoom sib txawv? Hom 304 stainless hlau bolts yog cim "A2-70" ntawm lub taub hau, thiab "A4-80" lossis "A4-80")

Qhov sib txawv ntawm qhov siab siab ntawm siab - cov kev tiv thaiv kub tsis taus bolts thiab bolts dog dig

Coob tus neeg yuam kev ntseeg tias siab - nqus tau lub zog thiab lub zog {{1} Lub zog Bolts, tab sis qhov no tsis yog. Cov tub ntxhais sib txawv ntawm lawv cov lus dag nyob rau hauv cov khoom siv ntau dua li cov qauv siv kub heev? Txawm li cas los xij, 42clo cov khoom tseem nyob ruaj khov nyob rau ntawm qhov kub (nyob ib ncig ntawm 360 degree) tsis muaj lub zog txo los yog hardness txo; Cov qhob hlau zoo nkauj (xws li cov hlau roj carbon lossis ua haujlwm feem ntau tsuas yog ua haujlwm hauv qab xyoo dhau los Yog li ntawd, siab - kub tiv taus bolts ua los ntawm 42crmo tau siv dav hauv qhov kev ua haujlwm siab xws li cov hlab ntsha siab thiab cov dej pheeb.

Tsis tas li ntawd, nyob rau hauv high - qhov kev ua kom muaj zog ntawm cov pa hluav taws xob muaj peev xwm tiv thaiv li 80} Kev co hauv lub zog ntawm 80} 42Cro siab - nqus kub heev bolts tuaj yeem tiv kwv yees li ntawm 200 deeg ua ntej loosening. Cov xeeb ceem no ntawm siab - cov dej kub tsis tuaj yeem hloov los ntawm cov bolts dog dig los ntawm cov bolts dog dig los ntawm cov bolts dog dig los ntawm cov bolts dog dig los ntawm cov bolts dog dig los ntawm cov bolts dog dig los ntawm cov bolts dog dig los ntawm cov bolts zoo tib yam; Kev hloov pauv yooj yim tuaj yeem yooj yim ua rau cov khoom poob vim li cas rau cov nyom, thiab cov kev pheej hmoo tsis txaus ntseeg tsis tuaj yeem zam ua ntej los ntawm cov tswv yim ceev.

High - Cov khoom siv kub tsis muaj txiaj ntsig rau cov piv txwv rau cov khoom, nws lub zog ua piv txwv, nws zoo li ntawm 12.9 {4 4 4}} bolts bolts. Tom qab kev tsim khoom, nws xav tau kev kho cua sov thiab cov oxide cov oxide dub; Galvanizing lossis Nickel plating yog feem ntau tsis tsim nyog, vim hais tias nyob rau hauv he} Cov txheej txheem ua tsis tiav, tsis yog tsuas yog ua haujlwm ntawm cov bolts vim muaj kub-kub ua tsis tiav.

Thaum lees txais siab - cov ntaub ntawv kub tawm yog qhov tseem ceeb tshaj plaws, thiab nws kuj tau raws li cov qauv kev tsim qauv- ob qho tseem ceeb. Yog tias cov khoom siv tau poob qis, txawm tias muaj kev nyuaj siab, nws tsis tuaj yeem ua tiav qhov kev ua tau zoo ntawm 42CRMO lossis 2205 chav hlau hauv siab- qhov chaw ib puag ncig. Yog li ntawd, thaum lub sij hawm txais, nws yog qhov tseem ceeb kom cov neeg xa khoom los muab cov ntawv xov xwm batch thiab cov ntaub ntawv tsom xam; Rau qhov sib txawv ib puag ncig, cov neeg ua haujlwm uas cuam tshuam yuav tsum tau txais kev cob qhia kev pab tshaj lij thiab cov qauv coj los ua kev ntsuas siab ntawm- tiv taus bolts.

Cov yam ntxwv thiab cov ntawv thov ntawm ob lub steeler steel bolts (noj 2205 ua piv txwv)
 

Duplex stainless hlau bolts twb tau ua lub luag haujlwm tseem ceeb thaum lub sijhawm tsim kho ntawm Hong Kong {0} hhau} Macau Macau choj. Thaum Lub Kaum Hlis 23, 2018, Hong Kong- hhuhai {}} Macau Choj tau qhib rau kev tsheb. Qhov no 55 {{9} ki} kilitometer Super Tus nqi ntawm Hong Kong, thiab Macau tau teeb tsa cov nqi logistic txuas ntxiv thiab txhawb kev txhim kho kev txhim kho ntawm peb thaj chaw. Hauv txoj haujlwm no, kev siv ntawm domonically tsim thiab tsim cov hlau stuplex stainless hlau tau mus txog 1,200 tons, ua kom tiav cov kev vam khom dhau los ntawm kev tsim kho stepless.

Yav dhau los,Duplex Stainless Hlau BoltsSiv hauv cov phiaj xwm hauv tsev hauv tsev feem ntau xav tau los ua; Txawm li cas los xij, kev lag luam lag luam uas tau koom nrog kev tsim kho Hong Kong {}} Qhov no tsis tsuas yog muab cov cim ua haujlwm rau cov neeg ua haujlwm hauv tsev tab sis kuj ua rau lawv lub zog ua kom muaj zog, tso lub hauv paus rau kev lag luam 'txoj siv thiab kev taug kev thiab kev taug kev ".

Duplex stainless hlau bolts (xws li 2205) tuaj yeem ntsib high-}}}}}}}}}}}}}}}}}}} Tus choj yuav tsum tau ua rau cov choj, feem ntau yog vim peb tus cwj pwm tseem ceeb:

Zoo heev corrosion: Nws corrosion kuj yog farIn ntau rau ntawm 304 stainless hlau bolts. Txuas hniav yog nyob rau hauv ib puag ncig cov tub rog ib puag ncig, qhov twg yog cov pa dej hiav txwv, uas muaj kwv yees li ntawm 2}} Kev tawm tsam corrosion nyob rau hauv ib puag ncig marine.

Siab zog ua tau zoo: Lub zog tensile ntawm 2205 duplex stainless hlau bolts yog li 850mpa}}}}}} {} {{{{ Nws qhov kev sim siab tiag tiag tau dhau los ntawm cov roj carbon steel 8.8-lub zog loj dua los yog sib npaug ntawm 640MPA), muab lub zog txhim khu kev lav kom ntau dua lossis muaj kev sib luag rau 640MPA), muab lub zog kom zoo dua lossis muaj zog kom muaj zog lav rau txoj kev sib txuas ntawm cov choj sib txuas. Lub zog siab ntawm ob lub stainless hlau los ntawm nws cov ntsiab lus derritic-ferritic-qhov tseeb (tsawg dua lossis sib npaug ntawm cov kev pheej hmoo ntawm cov pa roj carbon monoxide.

Zoo Vuam Compatibility: Hauv kev tsim kho choj, qee cov kab ke sib txuas yuav tsum tau kho los ntawm vuam. Lub Bolts Duplex steel bolts tuaj yeem sib haum nrog thaj chaw welded yam tsis muaj kev ua phem rau kev ua phem rau cov cua sov; Bolts zoo tib yam stainless hlau bolts, yog hais tias ze rau welded thaj chaw, ua tsis tau raws li cov cua kub, thiab ua tsis tau raws li kev sib txuas nrog kev sib txuas nrog. Qhov txiaj ntsig no kom zoo tshaj plaws ntawm cov ntsiab lus tsim nyog ntawm alloying ntsiab (xws li nitrogen) nyob rau hauv 2205 chav hlau, muab nws zoo thermal stability.

Ntxiv rau cov choj, 2205 duplexStainless Hlau Boltstseem muaj dav siv hauv cov chaw roj av roj av, Biofuelling, zaub mov ntim khoom siv, thiab lwm yam.: Nyob rau hauv roj av ntim khoom, thiab lwm yam zoo. Hauv Biofuel thiab cov zaub mov ua zaub mov, lawv cov khoom noj muaj txiaj ntsig zoo thiab nag lossis nag lossis nag lossis daus tuaj yeem ua kom pom kev huv thiab tsis txhob muaj paug ntawm cov khoom.

Cov Ntawv Sau Npe Ntxiv

Kev Hais Qhia Ntxiv ntawm cov khoom ua haujlwm ntawm qhov kub: cov lus dhau los uas "Duplex Stainless Hlau 2205 tuaj yeem tiv taus 600℃lossis 800 degree" tsis raug. Qhov tseeb, kev pabcuam txuas ntxiv kub ntawm 220 yuav tsum tsis pub tshaj 300 qib siab, thiab qhov siab tshaj plaws {Term kev pab kub yog li 400 degree. Tshaj li qhov no yuav ua rau tsis txaus ntseeg ntawm cov qauv duplex, txo qis corrosion tsis kam thiab lub zog.

Kev kho rau hauv qhov rooj vuam: Hauv kev tsim kho choj, bolts lawv tus kheej feem ntau tsis yog kev puas tsuaj ncaj qha los ntawm kev puas tsuaj rau kev ua kom muaj kev puas tsuaj rau kev ua haujlwm vim yog qhov siab tshaj plaws.

Kev kho rau cov ntsiab lus Carbon: Ib qho ntawm cov ntsiab lus zoo ntawm cov hlau duplex (xws li 2205) yog nws cov pa roj carbon qis, tsis yog "kuj yog". Cov ntsiab lus muaj roj carbon qis yog tus yuam sij rau nws qhov tseem ceeb ua rau muaj kev sib cuam tshuam ntawm cov ntsiab lus carbon monoxide (xws li 304).
