Puas yog 400 Series Stainless Steel xeb?

Cov hlau tsis xeb tau txais kev qhuas rau nws txoj kev tiv taus xeb, kev ruaj khov, thiab kev zoo nkauj. Txawm li cas los xij, tsis yog txhua qib hlau tsis xeb muab tib theem kev tiv thaiv tiv thaiv xeb. Ib qho ntawm cov lus nug feem ntau nug ntawm cov engineers, architects, thiab cov chaw tsim khoom yog:Puas yog 400 series stainless hlau xeb?

Cov lus teb luv luv yog:yog, 400 series stainless hlau tuaj yeem xeb tau, tshwj xeeb tshaj yog nyob rau hauv qee qhov xwm txheej ib puag ncig. Txawm hais tias nws tseem muaj kev tiv thaiv corrosion zoo dua li cov hlau carbon, nws cov kev ua tau zoo nyob ntawm qib tshwj xeeb, cov khoom sib xyaw, thiab kev pabcuam ib puag ncig. Hauv tsab xov xwm no, peb yuav dhia mus rau hauvkev tiv thaiv xeb ntawm 400 series stainless hlau, tshawb nrhiav cov yam uas cuam tshuam rau nws txoj kev ua tau zoo, thiab muab cov lus qhia txog qhov twg thiab yuav siv nws li cas kom zoo.

Ua tus neeg muag khoom uas ntseeg siab tau ntawm cov khoom siv hlau tsis xeb,sakysteelnyob ntawm no los pab koj nkag siab txog yuav ua li cas thiaj xaiv tau qhov qib zoo rau koj qhov project.

1. Nkag Siab Txog 400 Series Stainless Steel

Cov hlau stainless 400 series yog ib tsev neeg ntawmferritic thiab martensiticCov hlau tsis xeb. Tsis zoo li cov austenitic 300 series (zoo li 304 thiab 316), cov 400 series feem ntaumuaj nickel me ntsis los yog tsis muaj li, uas cuam tshuam loj heev rau kev tiv thaiv corrosion.

Cov qib 400 series feem ntau muaj xws li:

• 409Siv rau hauv cov tshuab pa tawm hauv tsheb

• 410: Qib martensitic dav dav

• 420: Paub txog kev siv cov khoom siv high hardness thiab cutlery

• 430: Kho kom zoo nkauj thiab tiv taus xeb rau kev siv sab hauv tsev

• 440: Cov pa roj carbon ntau, qib tawv siv rau cov hniav thiab cov cuab yeej

Cov qib no feem ntau muaj11% txog 18% chromium, uas tsim ib txheej oxide passive uas pab tiv thaiv xeb. Txawm li cas los xij, tsis muaj kev tiv thaiv ntawm nickel (raws li pom hauv 300 series), txheej no yogtsis ruaj khovnyob rau hauv cov xwm txheej nruj.

2. Vim li cas 400 Series Stainless Steel thiaj xeb tau?

Muaj ntau yam uas cuam tshuam raukev nyiam xebCov yam ntxwv ntawm 400 series stainless hlau:

a) Cov ntsiab lus Nickel tsawg

Nickel ua rau kom muaj zog duakev ruaj khov ntawm cov txheej txheem passive chromium oxideuas tiv thaiv cov hlau tsis xeb los ntawm kev xeb. Qhov tsis muaj nickel hauv 400 series qib ua rau lawvtsis tshua muaj zog tiv taus corrosionpiv rau 300 series.

b) Kev Ua Phem Rau Qhov Chaw

Yog tias raug rau:

• Cov tshuaj chloride ions (piv txwv li, los ntawm dej ntsev lossis cov ntsev deicing)

• Cov pa phem hauv kev lag luam

• Kev ntxuav tsis zoo lossis cov khoom seem ntawm kev tsim khoom
  cov txheej chromium oxide tiv thaiv tuaj yeem raug cuam tshuam, ua raukev xeb ntawm qhov pitting or cov xeb.

c) Kev saib xyuas tsis zoo lossis kev raug tshuaj lom

Nyob rau hauv cov chaw sab nraum zoov uas muaj av noo siab, nag acid, lossis ntsev tsuag, cov hlau 400 series uas tsis muaj kev tiv thaiv yuav muaj kev phom sij ntau dua rau kev xeb. Yog tsis muaj kev kho kom zoo, cov xim thiab xeb tuaj yeem tshwm sim dhau sijhawm.

3. Qhov Sib Txawv Ntawm Ferritic thiab Martensitic Qib

Cov koob 400 suav nrog ob qho tib siferriticthiabmartensiticcov hlau tsis xeb, thiab lawv coj tus cwj pwm txawv ntawm kev tiv taus xeb.

Ferritic (piv txwv li, 409, 430)

• Sib nqus

• Kev tiv thaiv corrosion nruab nrab

• Zoo rau sab hauv tsev lossis qhov chaw muaj xeb me ntsis

• Zoo dua formability thiab weldability

Martensitic (piv txwv li, 410, 420, 440)

• Kho tau los ntawm kev kho cua sov

• Cov ntsiab lus carbon ntau dua

• Muaj zog thiab hnav tsis kam

• Tsis tshua muaj corrosion-resistant dua li ferritic tshwj tsis yog tias passivated lossis coated

Kev nkag siab txog subclass twg koj siv yog qhov tseem ceeb rau kev kwv yees qhov kev ua tau zoo ntawm xeb.

4. Cov Kev Siv Hauv Lub Ntiaj Teb Tiag Tiag Thiab Lawv Cov Kev Xav Tau Txog Kev Xeb

Lubkev xaiv ntawm 400 series qibyuav tsum sib haum nrog lubkev cuam tshuam rau ib puag ncig ntawm daim ntawv thov:

• 409 Cov Hlau StainlessSiv ntau zaus hauv cov pa tso pa tawm hauv tsheb. Nws tuaj yeem xeb tau raws sijhawm tab sis nws muaj peev xwm tiv taus xeb tau rau cov chaw kub heev.

• 410 Cov Hlau StainlessSiv rau hauv cov riam, cov li qub, thiab cov khoom siv txuas. Yooj yim rau xeb yam tsis muaj kev cuam tshuam ntawm qhov chaw.

• 430 Cov Hlau Stainless: Nrov rau cov khoom siv hauv chav ua noj, dab dej, thiab cov vaj huam sib luag kho kom zoo nkauj. Zoo tiv taus xeb sab hauv tsev, tab sis yuav xeb yog tias siv sab nraum zoov.

• 440 Cov Hlau Stainless: Muaj zog heev rau cov hniav thiab cov cuab yeej phais, tab sis yooj yim rau kev puas tsuaj hauv qhov chaw noo noo yog tias tsis ua tiav kom raug.

At sakysteel, peb qhia cov neeg siv khoom txog qib 400 series uas tsim nyog tshaj plaws nyob ntawm lawv qhov kev raug ib puag ncig thiab kev cia siab ntawm kev xeb.
