2. Tshuaj Txhuam Kev Ntsuam Xyuas

Qhov sib txawv ntawm SS304 thiab SS316 lus dag hauv lawv cov tshuaj lom neeg muaj pes tsawg leeg. Ob leeg yog Austenitic stainless hlau nrog lub ntsej muag {{3} Cegential Cubic cov qauv, muab kev sib luag siab thiab tawv, tab sisSS316 muaj molybdenum, uas ua rau nws corrosion tsis kam, tshwj xeeb tshaj yog nyob rau hauv chloride - kev nplua nuj ib puag ncig.

2.1 Kev Ua Si Siv Tshuaj Ntau Tshaj Plaws

Tseem ceeb takaways:

Molybdenum yog tus sib txawv tseem ceeb, txhim kho chloride tsis kam nyob rau hauv SS316.

Cov pa roj carbon tsawg (304L thiab 316L) tau raug siv ntau dua rau welded mesh, txo cov kev pheej hmoo txaus ntshai.

2.2 lub luag haujlwm ntawm cov khoom siv alloy

Chromium (cr): Tsim cov ntom ntom criao₃ passive txheej. Thaum SS304 muaj me ntsis chromium, ntxiv rau ntawm molybdenum hauv SS316 ua rau nws zaj duab xis passive ntau ruaj khov nyob rau hauv kev txhoj puab heev.

Npib tsib caug (ni): Txav ruaj khov Austenite thiab txhim kho kev nruj, tshwj xeeb hauv qhov txias lossis siab -}} qhov chaw dej khov.

Molybdenum (mo): Txhim kho tiv thaiv kom pitting thiab crevice corrosion hauv chloride - cov kab mob nplua nuj. Qhov no yog qhov tseem ceeb hauv kev ua zaub mov noj, cov nroj tsuag tshuaj, lossis ib cheeb tsam ntug hiav txwv dej hiav txwv.

Carbon (c): Txo cov pa roj carbon txo carbide nag lossis daus uas ua raws cov ciaj ciam av thaum lub zog ua kom muaj zog tiv thaiv.

3. Metallurgical qauv thiab hlau kos tus cwj pwm

Ob leeg SS304 thiab SS316 yogAUSTENITIC, ua kom pom lub ntsej muag -} Chaw Sau Lus, muab kev sib txawv siab, muaj kev ruaj khov, thiab muaj kev muaj txiaj ntsig zoo. Cov khoom no yog qhov tseem ceeb rau cov xaim xees mesh, uas feem ntau cuam tshuam nrog lub cev khaub hlab txias rau cov kab hniav sib luag heev.

3.1 Austenitic zoo

Deventity Zoo Tshaj Rau Hlau Teeb Duab

Siab tawv ntawm cryogenic kub

Tsis -} sib nqus hauv cov ntawv qhia annealed

Siab tiv taus vim yog passive oxide txheej

Qhov zoo tagnrho rau intricate woven thiab welded mesh tsim

3.2 Ua haujlwm hnyav ua haujlwm

Hlau kos duab ua haujlwm - hardens austenitic stainless hlau, nce tensile thaum txo qis dua. Kev ua haujlwm - Harening cov nqi sib txawv me ntsis:

4. Cov Khoom Siv Neeg Kho Tshuab

Txawm hais tias cov alloys sib faib cov khoom zoo sib xws, hloov maj mam sib txawv cuam tshuam ntev {}} lub sij hawm kev ua tau zoo.

4.1 Cov Khoom Siv Neeg Kho Tshuab

Kev siv:

Ob txoj cai tiv thaiv deformation zoo nyob rau hauv kev raug ntxaij loads.

Qhov kev xaiv ntawm 304 thiab 316 yuav tsum tsom rauKev kis tau ib puag ncig ib puag ncig, tsis yog tshuab zog.

5. Weldability thiab cua sov -} cuam tshuam cheeb tsam (Haz)

Ntau cov ntawv thov cov hlau ntsuas kev sib koom ua ke siv vuam, qhov twg koomhaum ua pob qij txha yog qhov tseem ceeb.
