Kev Tiv Thaiv Kev Xeb Hlau Stainless: Yam Koj Yuav Tsum Paub

Cov hlau tsis xeb tau lees paub dav rau nws qhov ruaj khov, lub zog, thiab, qhov tseem ceeb tshaj plaws, nwskev tiv thaiv xebCov khoom no ua rau nws yog cov khoom siv xaiv rau ntau lub lag luam, los ntawm kev tsim kho thiab kev ua zaub mov mus rau kev tsim khoom siv hauv dej hiav txwv thiab tshuaj lom neeg. Tab sis dab tsi ua rau cov hlau tsis xeb tsis kam thiab puas tsuaj? Thiab koj yuav ua li cas kom koj cov hlau tsis xeb ua haujlwm raws li qhov xav tau hauv ntau qhov chaw sib txawv?

Hauv tsab xov xwm no, peb piav qhia txog kev tshawb fawb tom qab stainless hlau tiv taus xeb, ntau hom muaj, thiab yuav ua li cas xaiv qib zoo rau koj daim ntawv thov tshwj xeeb.

Dab tsi ua rau Stainless Steel Corrosion Resistant?

Tus yuam sij rau stainless hlau qhov corrosion tsis kam yog nyob rau hauv nwscov ntsiab lus ntawm chromiumTxhua cov hlau tsis xeb muaj tsawg kawg yog 10.5% chromium, uas ua rau cov pa oxygen hauv huab cua los ua ib qhotxheej txheem tsis ua haujlwmntawm chromium oxide rau ntawm qhov chaw. Cov txheej txheem tsis pom no, kho nws tus kheej tiv thaiv cov hlau hauv qab los ntawm kev oxidation thiab corrosion.

Qhov ntau dua cov chromium cov ntsiab lus, qhov zoo dua qhov corrosion tsis kam. Ntau qib stainless hlau kuj suav nrog lwm cov khoom sib xyaw xws linpib tsib, molybdenum, thiabnitrogenlos txhim kho qhov kev tiv thaiv no, tshwj xeeb tshaj yog nyob rau hauv cov chaw muaj kev kub ntxhov.

Cov Hom Kev Xeb thiab Kev Coj Tus cwj pwm ntawm Cov Hlau Stainless

Txawm tias cov hlau tsis xeb los kuj tsis tiv taus txhua yam xeb. Kev nkag siab txog cov hom hlau uas siv ntau yuav pab xaiv qib zoo.

1. Kev xeb dav dav

Qhov no yog kev xeb sib xws uas tshwm sim thoob plaws qhov chaw thaum raug rau cov chaw acidic lossis caustic. Cov qib zoo li 304 thiab 316 tiv taus hom no zoo.

2. Kev xeb ntawm qhov pitting

Tshwm sim nyob rau hauv cov chaw muaj chloride ntau xws li dej hiav txwv lossis thaj chaw pas dej ua ke. Cov qib uas muaj molybdenum xws li316 or 904Lmuab kev tiv thaiv zoo dua.

3. Kev xeb tawg

Tshwm sim rau hauv qhov chaw nqaim uas cov pa oxygen tsis tuaj yeem ncav cuag saum npoo kom tswj tau cov txheej passive. Kev xaiv cov qib carbon tsawg lossis cov qib alloy siab tuaj yeem pab tiv thaiv qhov no.

4. Kev Nyuaj Siab Corrosion Cracking

Qhov no yog kev sib xyaw ua ke ntawm kev ntxhov siab ntawm lub tshuab thiab ib puag ncig corrosive. Duplex stainless hlau lossis high-nickel alloys feem ntau siv los tiv thaiv qhov xwm txheej no.

Piv rau Cov Qib Stainless Steel Nrov

• 304 Cov Hlau Stainless: Kev tiv thaiv xeb zoo heev, tsim nyog rau sab hauv tsev lossis qhov chaw muaj xeb me ntsis.

• 316 Cov Hlau Stainless: Muaj molybdenum, ua rau nws zoo tagnrho rau kev siv hauv dej hiav txwv, tshuaj, thiab kev ua zaub mov.

• 430 Cov Hlau Stainless: Pheej yig dua tab sis muaj kev tiv thaiv corrosion qis dua, feem ntau yog siv rau hauv tsev.

• 904L Cov Hlau Stainless: Cov hlau stainless austenitic uas muaj cov hlau sib xyaw ua ke zoo heev uas tiv taus cov kua qaub thiab chlorides muaj zog.

• Duplex 2205: Muaj lub zog zoo dua thiab tiv taus kev ntxhov siab corrosion cracking.

Cov Yam Uas Cuam Tshuam Rau Kev Tiv Thaiv Kev Xeb Hlau Stainless

Muaj ntau yam sab nraud uas cuam tshuam rau seb cov hlau tsis xeb yuav ua haujlwm li cas hauv kev pabcuam:

• KubKub siab dua yuav ua rau xeb sai dua, tshwj xeeb tshaj yog nyob rau hauv cov chaw muaj kua qaub lossis chloride ntau.

• Kev raug rau ChloridesCov chloride ions muaj zog heev thiab tuaj yeem rhuav tshem cov txheej passive.

• Acidity thiab AlkalinityCov pH siab heev tuaj yeem ua rau cov hlau stainless hlau tsis zoo.
