Puas yog 400 Series Stainless Hlau Rust?

Stainless hlau yog ua kev zoo siab rau nws cov kev tiv thaiv corrosion, durability, thiab zoo nkauj thov. Txawm li cas los xij, tsis yog txhua qib stainless hlau muaj tib theem ntawm kev tiv thaiv xeb. Ib qho ntawm cov lus nug feem ntau ntawm cov engineers, architects, thiab manufacturers yog:Puas yog 400 series stainless hlau xeb?

Cov lus teb luv luv yog:Yog, 400 series stainless hlau tuaj yeem xeb, tshwj xeeb tshaj yog nyob rau hauv tej yam kev mob. Thaum nws tseem muaj kev tiv thaiv corrosion zoo dua li carbon steel, nws qhov kev ua tau zoo nyob ntawm qib tshwj xeeb, muaj pes tsawg leeg, thiab kev pabcuam ib puag ncig. Hauv tsab xov xwm no, peb yuav dhia mus rau hauvxeb kuj ntawm 400 series stainless hlau, tshawb xyuas cov xwm txheej cuam tshuam rau nws qhov kev ua tau zoo, thiab muab kev taw qhia txog qhov twg thiab yuav siv nws li cas kom zoo.

Raws li kev ntseeg siab ntawm cov khoom lag luam stainless hlau,sakysteel uanyob ntawm no los pab koj nkag siab tias yuav ua li cas thiaj paub cov kev xaiv thaum xaiv cov qib zoo rau koj qhov project.

1. Nkag siab txog 400 Series Stainless Hlau

400 series stainless hlau yog ib tsev neeg ntawmferritic thiab martensiticstainless hlau alloys. Tsis zoo li austenitic 300 series (xws li 304 thiab 316), 400 series feem ntaumuaj me ntsis los yog tsis muaj nickel, uas cuam tshuam rau corrosion kuj.

Feem ntau 400 series qib suav nrog:

  • 409 ib: Siv nyob rau hauv automotive exhaust systems

  • 410: General-purpose martensitic qib

  • 420: Paub rau siab hardness thiab cutlery daim ntaub ntawv

  • 430: Kho kom zoo nkauj thiab corrosion-resistant rau siv sab hauv tsev

  • 440: High-carbon, qib hardenable siv rau cov hniav thiab cov cuab yeej

Cov qib no feem ntau muaj11% mus rau 18% chromium, uas tsim ib tug passive oxide txheej uas pab tiv thaiv xeb. Txawm li cas los xij, tsis muaj kev tiv thaiv ntawm npib tsib xee (raws li pom hauv 300 series), txheej txheej no yogtsawg ruaj khovnyob rau hauv kev txhoj puab heev.

2. Vim li cas 400 Series Stainless Hlau Xwb?

Ntau yam cuam tshuam raurusting nyiamNtawm 400 series stainless hlau:

a) Cov ntsiab lus tsis tshua muaj Nickel

Nickel txhim kho lubstability ntawm passive chromium oxide txheejuas tiv thaiv stainless hlau los ntawm corrosion. Qhov tsis muaj nickel hauv 400 series qib ua rau lawvtsawg corrosion-resistantpiv rau 300 series.

b) Kev Tiv Thaiv Ntog

Yog raug rau:

  • Chloride ions (piv txwv li, los ntawm dej ntsev los yog deicing ntsev)

  • Muaj kuab paug

  • Kev tu tsis raug lossis kev tsim cov khoom seem
    kev tiv thaiv chromium oxide txheej tuaj yeem cuam tshuam, ua raupitting corrosion or xeb chaw.

c) Kev saib xyuas tsis zoo lossis raug raug

Nyob rau hauv ib puag ncig sab nraum zoov nrog cov av noo siab, kua qaub los yog tshuaj tsuag ntsev, tsis muaj kev tiv thaiv 400 series hlau yog qhov yooj yim rau corrosion. Yog tsis muaj kev kho kom zoo, staining thiab xeb tuaj yeem tshwm sim thaum lub sijhawm.

3. Qhov sib txawv ntawm qib Ferritic thiab Martensitic

400 series suav nrog ob qho tib siferriticthiabmartensiticstainless steels, thiab lawv coj txawv nyob rau hauv cov nqe lus ntawm xeb kuj.

Ferritic (eg, 409, 430)

  • Sib nqus

  • Nruab nrab corrosion kuj

  • Zoo rau sab hauv lossis me me corrosive ib puag ncig

  • Zoo formability thiab weldability

Martensitic (eg, 410, 420, 440)

  • Hardenable los ntawm kev kho cua sov

  • Cov ntsiab lus carbon ntau dua

  • Siab zog thiab hnav tsis kam

  • Tsawg corrosion-resistant tshaj ferritic tshwj tsis yog tias passivated los yog coated

To taub qhov subclass koj siv yog qhov tseem ceeb rau kev kwv yees kev ua haujlwm xeb.

4. Cov ntawv thov tiag tiag hauv ntiaj teb thiab lawv qhov kev cia siab rau Corrosion

Covkev xaiv ntawm 400 series qibyuav tsum dlhos covdaim ntawv thov kev raug mob ib puag ncig:

  • 409 Stainless hlau: Feem ntau siv nyob rau hauv automotive exhausts. Muaj peev xwm xeb dhau lub sijhawm tab sis muab kev tiv thaiv corrosion rau qhov chaw kub kub.

  • 410 Stainless hlau: Siv nyob rau hauv cutlery, li qub, fasteners. Yooj yim rau corrosion tsis nto passivation.

  • 430 Stainless hlau: Nrov rau cov khoom siv hauv chav ua noj, dab dej, thiab cov vaj huam sib luag zoo nkauj. Zoo hauv tsev corrosion kuj, tab sis yuav xeb yog siv sab nraum zoov.

  • 440 Stainless hlau: Siab hardness rau cov hniav thiab cov cuab yeej phais, tab sis raug rau pitting nyob rau hauv ib puag ncig ntub yog tias tsis ua tiav.

At sakysteel ua, peb qhia cov neeg siv khoom ntawm cov qib 400 series zoo tshaj plaws nyob ntawm lawv qhov kev cuam tshuam ib puag ncig thiab kev cia siab corrosion.

5. Sib piv 400 Series nrog 300 Series Stainless Hlau

Khoom 300 Series (piv txwv li, 304, 316) 400 Series (piv txwv li, 410, 430)
Cov ntsiab lus Nickel 8-10% Tsawg kawg rau tsis muaj
Corrosion Resistance Siab Nruab nrab mus rau qis
Sib nqus Feem ntau tsis-magnetic Sib nqus
Hardenability Tsis-hardenable Hardenable (martensitic)
Nqi Siab dua qis

Kev lag luam tawm rau kev txuag nqi nrog 400 series yogtxo corrosion kuj. Rausab hauv tsev, ib puag ncig qhuav, tej zaum nws yuav txaus. Tab sis raumarine, tshuaj, los yog tej yam kev mob ntub dej, 300 series yog qhov tsim nyog dua.

6. Tiv thaiv xeb ntawm 400 Series Stainless Hlau

Thaum 400 series stainless hlau tuaj yeem xeb, muaj ntau yamkev tiv thaivtxhawm rau txhim kho nws cov corrosion kuj:

a) Nto tiav

Polishing, passivation, los yog txheej (xws li hmoov txheej los yog electroplating) tuaj yeem txo qhov kev pheej hmoo ntawm xeb.

b) Kev tu thiab tu

Kev tu kom tsis tu ncua kom tshem tawm cov kab mob xws li ntsev, av, thiab cov khoom ua paug tuaj yeem pab khaws cia qhov chaw.

c) Kev ruaj ntseg zoo

Khaws cov ntaub ntawv hauv qhov chaw qhuav, npog kom txo tau cov dej noo thiab cov av noo tsawg kawg nkaus ua ntej siv.

d) Kev siv cov txheej txheem tiv thaiv

Epoxy lossis polyurethane txheej tuaj yeem tiv thaiv cov hlau nto ntawm qhov chaw corrosive.

sakysteel uamuab cov kev pabcuam muaj nqis ntxiv xws li polishing thiab txheej kom ntev lub neej ntawm koj 400 series stainless hlau cov khoom.
