Cov Hlau Dab Tsi Hauv Cov Hlau Stainless?

Cov hlau tsis xeb yog ib qho ntawm cov khoom siv tseem ceeb tshaj plaws uas siv thoob plaws hauv kev lag luam niaj hnub no, txij li kev tsim kho thiab kev thauj mus los mus rau kev ua zaub mov thiab cov khoom siv kho mob. Paub txog nws txoj kev tiv taus xeb thiab lub zog, cov hlau tsis xeb tsis yog hlau ntshiab - nws yog ib qho sib xyaw. Tab sis cov hlau twg yog cov hlau tsis xeb tiag tiag?

Hauv tsab xov xwm no, peb yuav tshawb nrhiav cov ntsiab lus tseem ceeb uas pom muaj nyob rau hauv cov hlau tsis xeb, vim li cas lawv thiaj li ntxiv rau, thiab txhua yam pab txhawb rau cov yam ntxwv uas ua rau cov hlau tsis xeb ua cov khoom siv tau ntau yam thiab muaj nqis. Ua tus neeg muab khoom thoob ntiaj teb ntawm cov khoom siv hlau tsis xeb zoo,sakysteelpab cov lag luam nkag siab thiab xaiv cov khoom sib xyaw kom haum rau lawv cov kev xav tau tshwj xeeb.

Dab tsi yog Stainless Steel

Cov hlau tsis xeb yog ib qho hlau sib xyaw ua los ntawm hlau, sib xyaw nrog lwm cov hlau thiab cov ntsiab lus los txhim kho nws txoj kev ua tau zoo. Lub ntsiab lus tseem ceeb ntawm cov hlau tsis xeb yog nws txoj kev tiv thaiv xeb thiab xeb, uas los ntawm qhov muaj nyob ntawmchromiumCov hlau tsis xeb sib txawv muaj cov hlau sib txawv nyob ntawm seb lawv siv li cas.

Cov Hlau Tseem Ceeb hauv Cov Hlau Stainless

1. Hlau (Fe)

Hlau yog cov hlau tseem ceeb hauv txhua hom hlau tsis xeb. Nws muab cov qauv, lub zog, thiab cov khoom sib nqus (hauv qee qib). Hlau ua rau feem ntau ntawm cov khoom sib xyaw hauv cov hlau tsis xeb, feem ntau ntau dua 50 feem pua.

2. Chromium (Cr)

Chromium yog qhov tseem ceeb uas ua rau cov hlau tsis xeb tsis kam. Cov hlau tsis xeb yuav tsum muaj tsawg kawg10.5 feem pua ​​​​​​chromiumkom raug cais ua stainless. Chromium tsim ib txheej oxide nyias nyias rau ntawm qhov chaw uas tiv thaiv cov khoom ntawm xeb.

3. Nickel (Ni)

Muaj nickel ntxiv rau ntau hom stainless hlau kom txhim kho kev ua haujlwm, kev tawv, thiab kev tiv taus xeb, tshwj xeeb tshaj yog nyob rau hauv cov chaw acidic. Nws kuj pab kom cov qauv siv lead ua austenitic ruaj khov, ua rau cov hlau tsis muaj hlau nplaum hauv qee hom xws li 304 thiab 316.

4. Cov pa roj carbon (C)

Cov pa roj carbon ua rau lub zog thiab qhov tawv dua. Txawm hais tias cov pa roj carbon ntau tuaj yeem ua rau cov khoom tawg yooj yim, tab sis me me ua rau lub zog thiab kev tiv taus kev hnav. Hauv cov hlau tsis xeb, cov pa roj carbon feem ntau raug khaws cia qis kom tswj tau qhov vuam tau thiab kev tawv.

5. Manganese (Mn)

Manganese ua rau cov hlau stainless muaj zog thiab tawv dua thiab pab ua cov txheej txheem ua hlau los ntawm kev tshem tawm cov pa oxygen thiab sulfur. Nws kuj pab ua kom cov theem austenitic ruaj khov hauv qee cov hlau stainless.

6. Molybdenum (Mo)

Molybdenum ua rau kom tsis txhob xeb, tshwj xeeb tshaj yog nyob rau hauv cov chaw uas muaj chloride raug xws li dej ntsev lossis kev ua tshuaj lom neeg. Cov qib zoo li316 stainless hlaumuaj 2 txog 3 feem pua ​​​​molybdenum rau kev ua kom ruaj khov ntxiv.

7. Silicon (Si)

Silicon ua haujlwm ua tus deoxidizer thaum lub sijhawm tsim hlau thiab txhim kho kev tiv thaiv oxidation ntawm qhov kub siab. Nws pab txhawb rau qhov tawv thiab lub zog ntawm stainless hlau.

8. Nitrogen (N)

Nitrogen siv los ua kom cov hlau stainless muaj zog dua yam tsis muaj kev cuam tshuam rau kev ductility. Nws yog qhov tshwj xeeb tshaj yog siv rau hauv cov hlau duplex stainless, qhov twg nws txhim kho kev tiv thaiv corrosion thiab toughness.

Cov Ntsiab Lus Ntxiv

Qee cov hlau tsis xeb muaj cov khoom me me rau cov hom phiaj tshwj xeeb:

• Titanium (Ti): Tiv thaiv cov carbide precipitation thiab txhim kho weldability.

• Tooj liab (Cu): Txhim kho kev tiv thaiv xeb hauv qee qhov chaw tshuaj lom neeg.

• Txhuas (Al): Txhim kho kev tiv thaiv oxidation hauv cov ntawv thov kub siab.

• Niobium (Nb): Ntxiv rau lub zog thiab tiv taus intergranular corrosion.

Qhov sib xyaw ua ke sib txawv nyob ntawm qib hlau tsis xeb. Piv txwv li,304 stainless hlaumuaj chromium thiab nickel, thaum430 stainless hlaumuaj chromium tab sis tsis muaj nickel, ua rau nws muaj hlau nplaum ntau dua thiab pheej yig dua.

Vim Li Cas Kev Sau Ntawv Tseem Ceeb

Kev sib xyaw ua ke ntawm cov hlau hauv cov hlau tsis xeb txiav txim siab nws:

• Kev tiv thaiv xeb

• Lub zog kho tshuab

• Kev tiv thaiv kub

• Kev ua tau zoo

• Cov khoom sib nqus

Kev xaiv cov hlau tsis xeb kom raug rau ib qhov project yuav tsum nkag siab txog cov khoom sib xyaw thiab seb cov ntsiab lus sib cuam tshuam li cas.
