Qhov txawv ntawm 304 thiab 201 stainless hlau yog dab tsi?

Qhov Sib Txawv Ntawm Qhov Chaw
Muaj qhov sib txawv ntawm ob qho no los ntawm qhov chaw. Piv rau qhov ntawd, 201 cov khoom siv vim yog cov ntsiab lus manganese, yog li cov khoom siv no ntawm cov hlau tsis xeb kho kom zoo nkauj raj xim tsis ci, 304 cov khoom siv vim tsis muaj cov ntsiab lus manganese, yog li qhov chaw yuav du thiab ci dua. Qhov sib txawv ntawm qhov chaw yog ib sab, vim tias lub Hoobkas stainless hlau raj yuav tom qab kev kho qhov chaw, yog li txoj kev no tsuas yog haum rau qee qhov sib txawv ntawm cov khoom siv raw stainless hlau tsis tau ua tiav.

 

Kev Ua Tau Zoo Txawv

201 stainless hlaukev tiv thaiv corrosion, acid thiab alkali tsis kam yog qhov tsis muaj zog piv rau304 stainless hlau, thiab 201 stainless hlau hardness yog siab dua 304 stainless hlau.

Cov mis tshuaj ntawm 201 yog 1Cr17Mn6Ni5, cov mis tshuaj ntawm 304 yog 06Cr19Ni10. qhov sib txawv ntawm lawv yog cov ntsiab lus sib txawv ntawm nickel thiab chromium, 304 yog 19 chromium 10 nickel, thaum 201 yog 17 chromium 5 nickel. Vim muaj 2 hom stainless hlau kho kom zoo nkauj yeeb nkab, cov ntsiab lus nickel sib txawv, yog li 201 corrosion tsis kam, acid thiab alkali tsis kam yog qhov tsis zoo dua li 304. Cov ntsiab lus carbon ntawm 201 siab dua 304, yog li 201 nyuaj dua thiab brittle dua 304, thaum 304 muaj zog dua, yog li nws tsim nyog rau kev siv tom qab.

Tam sim no muaj ib qhohlau tsis xebKev sim tshuaj hauv khw, tsuav yog ob peb tee dej xwb ces yuav paub qhov txawv ntawm cov hlau tsis xeb hauv ob peb feeb xwb, lub hauv paus ntsiab lus yog ua kom cov ntsiab lus uas muaj nyob hauv cov khoom siv nrog kev txheeb xyuas cov tshuaj hauv cov tshuaj kom tsim cov tshuaj lom neeg uas muaj xim. Qhov no tuaj yeem paub qhov txawv ntawm 304 thiab 201 cov ntaub ntawv sai sai.
Daim ntawv thov sib txawv
Vim muaj cov tshuaj lom neeg sib txawv, 201 yooj yim xeb dua li 304 stainless hlau. Yog li ntawd, 201 feem ntau tsuas yog siv rau hauv qhov chaw qhuav ntawm kev tsim kho thiab kho kom zoo nkauj hauv kev lag luam. Thiab 304 vim muaj kev tiv thaiv corrosion, acid thiab alkali tsis kam thiab lwm yam khoom muaj qhov zoo dua, daim ntawv thov dav dua, dav dua, thiab tsis tsuas yog txwv rau cov ntawv thov kho kom zoo nkauj xwb.

Qhov Txawv ntawm Tus Nqi

304 stainless hlau vim muaj qhov zoo ntawm kev ua tau zoo hauv txhua yam, yog li nws kim dua piv rau 201 stainless hlau.

 

Paub txog txoj kev yooj yim ntawm 304 thiab 201 stainless hlau phaj

304 stainless hlau vim nws txoj kev tiv thaiv corrosion zoo heev feem ntau siv rau hauv txheej sab hauv (piv txwv li, kev sib cuag ncaj qha nrog dej), 201 stainless hlau vim nws txoj kev tiv thaiv corrosion tsis zoo, tsis tuaj yeem siv rau hauv txheej sab hauv, feem ntau siv rau hauv txheej sab nraud ntawm lub tank rwb thaiv tsev. Tab sis 201 pheej yig dua 304, feem ntau siv los ntawm qee tus neeg ua lag luam tsis muaj kev ntseeg ua txuj ua 304, nrog 201 stainless hlau ua los ntawm stainless hlau dej tank kev pabcuam lub neej luv heev, feem ntau 1-2 xyoos tuaj yeem raug corroded los ntawm dej, tawm hauv tus neeg siv nrog kev nyab xeeb kev nyab xeeb.

Txoj kev yooj yim los txheeb xyuas ob yam khoom siv:
1. 304 thiab 201 stainless hlau siv rau hauv lub tank dej stainless hlau, qhov chaw feem ntau yog sib dua. Yog li peb pom txoj kev los ntawm qhov muag liab qab, kov tes. Qhov muag liab qab kom pom 304 stainless hlau muaj qhov ci ntsa iab zoo heev, kov tes du heev; 201 stainless hlau yog xim tsaus, tsis muaj ci ntsa iab, kov muaj qhov ntxhib thiab tsis du. Tsis tas li ntawd, tes yuav ntub dej, feem, kov ob hom stainless hlau phaj, kov dej ntawm 304 phaj cov cim tes yooj yim dua los rho tawm, 201 tsis yooj yim los rho tawm.
2. Siv lub tshuab sib tsoo uas muaj lub log sib tsoo maj mam xuab ob hom ntawv, xuab 201 ntawv kom ntev dua, tuab dua, ntau dua, thiab vice versa, 304 ntawv luv dua, nyias dua, tsawg dua. Lub zog xuab yuav tsum sib dua, thiab 2 hom zog xuab yog sib xws, yooj yim kom paub qhov txawv.
3. Nrog cov hlau stainless pickling cream tau coated rau hauv 2 hom stainless hlau phaj. 2 feeb tom qab, saib cov xim stainless hlau hloov pauv ntawm txheej. Xim dub rau 201, dawb lossis tsis hloov xim rau 304.
