Cov kev sib txawv ntawm cov txheej txheem txog 304 thiab 316 steel hlau

Date:May 12, 2019

Hais txog kev saib xyuas ntawm 304 thiab 316 stainles steel, nws yog diferent tiag tiag. Hauv peb cov khoom lag luam niaj hnub, peb tuaj yeem siv cov roj electroplating lossis oxidation-resistant kom paub tseeb tias cov pa roj carbon steel nto, tab sis kev tiv thaiv no tsuas yog zaj duab xis. Yog tias tiv thaiv txheej pov tseg, hauv qab steel pib xeb. Qhov ua hauj corrosion ntawm stainless hlau nyob ntawm lub caij chromium. Thaum cov nqi ntawm cov chromium ntxiv nce mus txog 10.5%, cov atmospheric corrosion kuj ntawm stainless hlau yuav nce siab, tab sis, yog tias cov ntsiab lus chromium ntau dua, txawm hais tias nws tuaj yeem txhim kho qee yam corrosion kuj. Tab sis tsis pom tseeb. Qhov laj thawj yog tias qhov kev hloov kho no hloov cov nplaim oxide mus rau ib qho oxide saum npoo zoo ib yam li qhov tsim los ntawm cov ntshiab chromium hlau, tab sis txheej txheej oxide no yog nyias heev, thiab nws tuaj yeem ncaj qha pom cov lus ntuj ntawm cov hlau saum npoo. Txhawm rau muab stainless hlau tshwj xeeb nto. Ntxiv mus, yog hais tias qhov saum npoo puas lawm, lub npoo steel nto yuav hnov mob nrog cov cua. Tus txheej txheem no qhov tseeb yog qhov kev kho tus kheej, uas rov ua cov zaj duab xis passivation thiab tuaj yeem txuas ntxiv tiv thaiv.



Yog li ntawd, txhua tus hlau stainless muaj cov yam ntxwv sib xws, uas yog, cov ntsiab lus chromium yog siab dua 10.5%, thiab qib siab dua qib steel tseem muaj npib tsib xee, xws li 304. Qhov ntxiv ntawm molybdenum tuaj yeem txuas ntxiv txhim kho mus rau qhov chaw muaj zog, tshwj xeeb tshaj yog tiv thaiv chloride-muaj cov atmospheres , uas yog rooj plaub nrog 316.



Hauv qee thaj chaw muaj kev lag luam thiab chaw ntug dej hiav txwv, cov pa phem yuav loj heev, saum npoo yuav qias neeg, thiab txawm tias xeb dhau los. Txawm li cas los xij, yog tias npib tsib xee-uas muaj cov hlau stainless siv, cov nyhuv zoo nkauj rau thaj chaw sab nraum zoov tuaj yeem tau txais. Yog li no, peb cov kab hlau rhuav phab ntsa, phab ntsa thiab ru tsev yog xaiv los ntawm 304 stainless hlau, tab sis nyob rau qee qhov muaj kev lag luam lossis chaw ua cua, 316 stainless hlau yog qhov kev xaiv zoo.
