Corrosion kuj

316L yog dav siv hauv kev lag luam tshuaj vim nws zoo heev corrosion kuj. 316L kuj yog ib qho derivative ntawm 18-8 austenitic stainless hlau, nrog 2 mus rau 3 feem pua ​​Mo ntxiv. Raws li 316L, ntau hom hlau kuj tau muab los. Piv txwv li, 316Ti yog muab los ntawm kev ntxiv me me ntawm Ti, 316N yog muab los ntawm kev ntxiv me me ntawm N, thiab 317L yog muab los ntawm kev nce cov ntsiab lus ntawm Ni thiab Mo.

Feem ntau ntawm 316L uas twb muaj lawm nyob rau hauv kev ua lag luam yog tsim raws li American Standard. Rau cov nqi txiav txim siab, steel mills feem ntau khaws Ni cov ntsiab lus ntawm S31603 Hlau hmoov txhaj tshuaj molded cov khoom kom tsawg li tsawg tau. Cov txheej txheem Asmeskas tau teev tseg tias Ni cov ntsiab lus ntawm 316L yog 10-14 feem pua, thaum cov txheej txheem Nyij Pooj tau hais tias Ni cov ntsiab lus ntawm 316L yog 12-15 feem pua. Raws li tus qauv yam tsawg kawg nkaus, muaj 2 feem pua ​​​​qhov sib txawv ntawm Ni cov ntsiab lus ntawm American Standard thiab Japanese Standard, uas yog qhov loj heev thaum xav txog tus nqi. Yog li ntawd, thaum yuav 316L cov khoom, cov neeg siv khoom tseem yuav tsum tau saib kom meej seb cov khoom xa mus rau ASTM lossis JIS cov qauv.

Cov ntsiab lus Mo ntawm 316L ua rau cov hlau no muaj kev tiv thaiv corrosion zoo heev, thiab tuaj yeem siv nyab xeeb hauv ib puag ncig uas muaj halogen ions xws li Cl-. Txij li thaum daim ntawv thov tseem ceeb ntawm 316L yog nws cov khoom siv tshuaj, steel mills muaj qhov yuav tsum tau qis me ntsis rau kev soj ntsuam saum npoo ntawm 316L (piv rau 304), thiab cov neeg siv khoom uas xav tau ntau dua saum npoo yuav tsum ntxiv dag zog rau kev tshuaj xyuas saum npoo.

Qhov sib piv ntawm qhov ntsuas kub tshwj xeeb (20 degree): 0.502kJ / (g * K)

Kev kho cua sov: Kev daws teeb meem 1010 ~ 1150 degree ceev txias.

Microstructure: Cov yam ntxwv ntawm lub koom haum yog austenitic stainless hlau.

Paub qhov txawv

SUS316L stainless hlau:

Qhov ob feem ntau siv stainless hlau 304 thiab 316 (los yog sib haum rau German / European tus qauv 1.4308, 1.4408), qhov sib txawv tseem ceeb ntawm cov tshuaj muaj pes tsawg leeg ntawm 316 thiab 304 yog tias 316 muaj Mo, thiab nws feem ntau lees paub tias 316 muaj kev tiv thaiv corrosion zoo dua. . Nws yog corrosion resistant ntau tshaj 304 nyob rau hauv kub kub ib puag ncig. Yog li ntawd, nyob rau hauv qhov kub thiab txias ib puag ncig, engineers feem ntau xaiv qhov chaw ua los ntawm 316 cov ntaub ntawv. Tab sis lub npe hu ua tsis muaj dab tsi kiag li, nyob rau hauv cov concentrated sulfuric acid ib puag ncig, tsis txhob siv 316 txawm tias kub npaum li cas. Txwv tsis pub, nws yuav ua rau muaj teeb meem loj. Txhua tus neeg uas kawm txog kev siv tshuab tau kawm cov xov, thiab nco ntsoov tias txhawm rau tiv thaiv cov xov los ntawm kev ntes ntawm qhov kub thiab txias, yuav tsum siv cov roj nplua nyeem tsaus nti: molybdenum disulfide (MoS2), los ntawm ob qhov kev txiav txim siab tuaj yeem kos: Ib qho: Mo. Qhov tseeb yog cov tshuaj tiv thaiv kub kub (koj puas paub dab tsi crucible yog siv los yaj kub? Molybdenum crucible!). Qhov thib ob: Molybdenum tuaj yeem yooj yim hnov ​​​​mob nrog cov tshuaj sulfur ions los ua sulfide. Yog li tsis muaj ib hom stainless hlau uas yog super invincible thiab corrosion-resistant. Nyob rau hauv qhov kev ntsuam xyuas zaum kawg, stainless hlau yog ib daim hlau uas muaj impurities ntau dua (tab sis cov impurities no muaj corrosion-resistant ntau dua hlau), thiab hlau tuaj yeem hnov ​​​​mob nrog lwm yam khoom.
