Spa -} hreasing hlauYog lub siab - Kev ua tau zoo cov ntaub ntawv siv dav hauv kev ua si sab nraud.
Paub rau nwszoo tshaj corrosion Kuj, Muaj zog, thiab muaj cov kev xaiv ruaj khov, nws tau dhau los ua kev xaiv zoo nyob rau hauv kev lag luam xws li ntim, kev thauj khoom, thiab sab nrauv qauv.
Kab lus piav qhiadab tsi spa -} h huab cua dav hlau yog, nws cov tshuaj thiab cov kws kho mob tshuab, thiab vim li cas nws muaj cov txiaj ntsig tseem ceeb tshaj cov pa roj carbon hlau.
Dab tsi yog spa -} hreasing steel?
Spa -} hreasing hlau, tseem hu uaatmospheric corrosion -} tiv taus hlau, yog qhov qis {- cov hlau alleoy uas yog cov lus dag ntawm cov hlau ua kom zoo li qub hlau thiab stainless hlau.
Nws yog tsim los ntawm kev ntxiv cov khoom siv xws li tooj liab, chromium, npib tsib xee, thiab vanadium rau cov hlau.
Cov ntsiab lus sib dhos no ua rau cov xim tuab thiab ruaj khov rau ntawm cov hlau saum npoo av, uas yuav cuam tshuam rau cov nkag mus ntxiv.
Qhov no txhais tau tiasSpa -} hreasing hlautsis tsuas yog muajLub zog, ductility, thiab nkees ua rau ntawm cov hlau zoo tib yam, tab sis kuj muab2-8 lub sij hawm zoo corrosion tsis kam.
Cov yam ntxwv tseem ceeb ntawm spa -} hreasing hlau
Siab corrosion tsis kam
Kev tiv thaiv Patina ntau heev txo cov xeb tsis xeb.
Ua tau zoo hauv kev lag luam thiab cov khoom siv hluav taws xob.
Txo ntev -} lub sij hawm tu cov nqi piv nrog cov hlau dog dig.
Cov Khoom Ruaj Ntseg Ruaj Ntseg
Paib lub zog ntau dua los yog sib npaug rau 355 mpa
Tensile lub zog loj dua los yog sib npaug rau 490 MPa
Zoo toughness thiab elongation kev ua tau zoo
Kev qaug zog zoo heev rau ntev - sij hawm thauj -}}}}}}}}} cov kabmob siv
Zoo Txheej Txheem
Tuaj yeem txiav, welded, thiab khoov tau yooj yim.
Haum rau cov txheej txheem sib txuas hlau.
Durability & thiav
Kev pabcuam lub neej nyob rau sab nraum zoov qhov chaw tuaj yeem ncav kaum xyoo tsis muaj tsho tiv no.
Ua kom muaj kev nyab xeeb nyab xeeb thiab kev pom kev pom txawm hais tias tom qab ntev - lub sij hawm kis tau.

Cov ntawv thov ntawm Spa -} hreasing hlau
Vim nwslub zog thiab lub zog ntawm cov corroscerion, Spa - h yog siv nyob rau hauv:
- Thawv Raug- Qhov twg cov pa roj carbon steel corrodes yooj yim heev.
- RAILway tsheb & Cov khoom siv thauj khoom- Txhim kho qhov tsis txaus ntseeg nyob rau hauv cov xwm txheej sab nraum zoov.
- Roj Derricks & Drilling Platforms- Nyob qhov twg ntev {- lub sij hawm corrosion yog qhov tseem ceeb.
- Siv & Txuas Hniav- Rau phab ntsa sab nrauv, cov tsheb ciav hlau, thiab sab nraum zoov cov qauv hlau.
- Toj roob hauv pes & nroog tsim- Duab puab, kos npe, thiab nthuav tawm cov khoom kos duab.
Tus nqi txiav txim siab
Piv nrog cov hlau zoo tib yam,Spa -} hreasing hlauyog hais txog60% kim duaCov. Tus nqi siab dua yog kev ncaj ncees los ntawm nws lub neej kev pab siv sijhawm ntev dua, txo tus nqi txij nkawm, thiab kev ua haujlwm zoo dua qub. Dhau lub sij hawm ntev, nws muabzoo dua nyiaj txiag muaj nuj nqistshaj cov pa hlau.

RauZoo dua nkag siab spa -} hreasing hlau, nws yog ib qho tseem ceeb kom paub txog nws txoj haujlwm tshwj xeeb ntawm cov hlau roj carbon thiab hlau.
Nrogsiab corrosion tsis kam, Cov Khoom Siv Zoo Zog, thiabCov kev xav tau txij nkawm tsawg, nws yog cov khoom siv ntawm kev xaiv rau kev thov sab nraum zoov xws li ntim, cov tsheb ciav hlau, cov choj, thiab cov haujlwm architectural.
Los ntawm kev sivSpa -} hreasing hlau, Kev lag luam tuaj yeem txuas ntxiv lub neej ntawm cov qauv thaum tseem txo cov nqi cuam tshuam nrog kev kho cov nqi, rov qab ua dua, thiab hloov chaw.
