Dab tsi yog qhov txawv ntawm 316 thiab 321 stainless hlau?

316 vs 321 Stainless hlau: Yuav ua li cas xaiv cov khoom zoo rau koj cov kev xav tau?

Hauv kev lag luam tsim thiab tsim qauv tsim, 316 thiab 321 stainless hlau tau siv dav siv vim lawv ua tau zoo heev. Txawm li cas los xij, muaj qhov sib txawv tseem ceeb ntawm ob hauv cov tshuaj muaj kuab lom, corrosion tsis kam, muaj kub tsis kam thiab muaj cov xwm txheej muaj feem xyuam. Kab lus no yuav tob tob seb cov tseem ceeb ntawm ob los pab koj ua qhov kev xaiv scientific.

1. Tshuaj lom neeg sib xyaw
316 Stainless Hlau Sib Sau: Raws li {16-18}}}}}}}}}}% molybdenum (mo). Qhov kev sib ntxiv ntawm molybdenum heev txhim kho nws kev tiv thaiv kom pitting thiab crevice corrosion, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig muaj chloride ions (xws li seawater thiab ntsev).
321 stainless hlau titanium lub caij: 0. {}. {}.}}.

2. Corrosion Kuj:
316 Stainless hlau tiv thaiv dej hiav txwv corrosion: muaj cov khoom siv acidic thiab chloride chaw, khoom siv dej hiav txwv, thiab lwm yam kev pheej hmoo.
321 stainless hlau tiv thaiv kev kub siab: titanium stabilation tsis kam rau nws kom muaj kev kub ntxhov siab rau lub sijhawm ntev (xws li boilers, kev hloov cua sov).
Cov kev txwv: cov xeb tawm tsam yog qhov qis me ntsis rau 316 hauv cov kua qaub muaj zog lossis muaj cov tshuaj ntsuab.

Dab tsi yog qhov ntau tshaj plaws kev ua haujlwm ntawm 316 stainless hlau?
Kev ua haujlwm ua haujlwm txuas ntxiv tuaj yeem ncav cuag 870 degree, thiab nws tuaj yeem tiv taus 1200-1300 degree rau lub sijhawm luv luv, uas haum rau nruab nrab ib puag ncig.
Siab kub npaum li cas txog 321 uas muaj lub zog tiv thaiv tau li cas?
Vim tias qhov kub siab nyob hauv titanium, kev ua haujlwm txuas ntxiv tau nce rau 980 degree, thiab cov creep tsis zoo, uas yog tsim nyog rau kev ua kom hnyav rau lub dav hlau cav thiab cov khoom cua sov.

Cov Khoom Siv Neeg Kho Tshuab thiab Cov Txheej Txheem
Cov txiaj ntsig lub zog ntawm 316 stainless hlau (ntau dua los yog sib npaug) yog siab dua li ntawm 321 (ntau dua los yog sib npaug ntawm 205 MPa), tab sis 321 muaj zog ntau dua. 316 Yuav tsum muaj kev kho kom zoo tom qab vuam los kho kom rov qab corrosion tsis kam;
321 tsis xav tau kev kho cua sov tom qab vuam vim titanium inhibits carbide nag lossis los thiab cov txheej txheem yooj yim dua. 321 muaj qhov qis dua rau cov tawv tawv vim yog ua haujlwm txias, thiab yog qhov tsim nyog rau kev ua cov txheej txheem nyuaj.

3.Cost thiab Tus Nqi
316 Stainless hlau: Tus nqi yog tus nqi siab (txog $ 3. {}}}}}}
321 Tus nqi stainless hlau: tus nqi qis dua 316 (txog $ 2. {}}. 5 / kg), haum rau cov kev ua tau zoo nrog kev ua tau zoo.

Yog tias cov peev nyiaj tau txwv thiab ib puag ncig yog qhov me me, 304 stainless hlau tuaj yeem txiav txim siab; Yog tias ob leeg raug nqi thiab cov kev ua tau kub thiab kub tau txais, 321 yog kev xaiv zoo dua.
Yuav 321 stainless hlau xeb?
Nws tsis yooj yim rau xeb hauv cov chaw qhuav lossis tsis muaj zog yog tias muaj cov kua qaub muaj zog lossis cov tshuaj ntsuab muaj zog (xws li txheej txheem).
316 thiab 321 hloov ib leeg?
Nws nyob ntawm cov kev xav tau. Piv txwv li, 316 tsis tuaj yeem hloov 321 rau siab dua siab tshaj 900 degree; 321 muaj qhov tsis muaj txiaj ntsig corrosion tsis txaus nyob hauv cov av marine thiab tsis tuaj yeem hloov 316.
