Taw qhia
304 stainless hlau, tseem hu ua 18/8 stainless hlau, yog ib qho kev xaiv nrov rau ntau yam kev siv vim nws zoo corrosion kuj thiab siab zog. Tab sis zoo li txhua yam khoom siv, nws muaj nws cov kev txwv thiab qhov tsis zoo. Hauv tsab xov xwm no, peb yuav tham txog qhov tsis zoo ntawm 304 stainless hlau kom ntxaws.
Corrosion kuj
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm 304 stainless hlau yeeb nkab khoom yog nws cov corrosion kuj. Txawm li cas los xij, nws tseem ceeb heev uas yuav tsum nco ntsoov tias qhov kev tiv thaiv corrosion tsis yog qhov tseeb.
Ib qho ntawm cov teeb meem loj ntawm304 stainless hlau rajcov khoom yog hais tias nws yog susceptible rau pitting corrosion. Pitting corrosion yog ib qho chaw hauv cheeb tsam ntawm corrosion uas ua rau tsim cov pits me me ntawm cov khoom siv. Cov pits no tuaj yeem ua rau lub cev tsis muaj zog ntawm cov khoom siv lub sijhawm.
304 stainless hlau phajcov ntaub ntawv tseem yog qhov yooj yim rau crevice corrosion. Crevice corrosion tshwm sim thaum qhov sib txawv me me los yog cov ntaub ntawv crevice ntawm ob qhov chaw. Qhov sib txawv no tuaj yeem ntes cov tshuaj corrosive thiab tsim ib qho chaw uas muaj corrosion tuaj yeem tshwm sim.
Kev kis kab mob
Lwm qhov teeb meem muaj peev xwm nrog 304 stainless hlau yog kev sib kis.
Yog tias cov khoom tsis raug ntxuav kom zoo los yog khaws cia, nws tuaj yeem ua paug nrog lwm yam khoom. Qhov no tuaj yeem tshwm sim yog tias cov khoom raug rau cov dej tsis zoo lossis yog siv rau hauv qhov chaw muaj kab mob siab.
Kev sib kis tuaj yeem cuam tshuam qhov kev tiv thaiv corrosion ntawm cov khoom thiab ua rau ua tsis tiav ntxov ntxov. Nws tseem tuaj yeem ua rau cov khoom siv tsis zoo rau kev siv qee yam kev siv, xws li kev ua zaub mov lossis khoom siv kho mob.
Lub zog
304 stainless hlaupaub txog nws lub zog siab, tab sis nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias lub zog no tuaj yeem yog qhov tsis zoo.
Hauv qee qhov kev siv, lub zog siab ntawm cov khoom siv tau tuaj yeem yog lub luag haujlwm. Piv txwv li, nyob rau hauv daim ntawv thov qhov twg ductility thiab toughness yog tseem ceeb tshaj sheer lub zog, ib tug txawv cov ntaub ntawv yuav yog ib tug zoo xaiv.
Tsis tas li ntawd, lub zog siab ntawm 304 stainless hlau tuaj yeem ua rau nws nyuaj rau cov txheej txheem thiab vuam, uas tuaj yeem ua rau cov nqi ntau lawm lossis ua rau qee yam kev tsim khoom ua tsis tau.
Thaum tshav kub kub kuj
304 UNS S30400 stainless hlaumuaj cov cua kub zoo, tab sis nws tsis zoo rau kev siv hauv cov ntawv thov kub.
Ntawm qhov kub siab tshaj 800 degrees Fahrenheit, cov khoom siv tuaj yeem pib muaj carbide nag lossis daus. Carbide nag lossis daus yog thaum carbon atoms ua ke nrog chromium los ua chromium carbides. Qhov no tuaj yeem ua rau depletion ntawm chromium hauv cov khoom, uas tuaj yeem cuam tshuam nws cov kev tiv thaiv corrosion.
Qhov no txhais tau hais tias 304 stainless hlau tsis haum rau siv rau hauv cov ntawv thov uas nws yuav raug kub hnyiab tau rau lub sijhawm ntev.

Thaum1.4301 khoom 304 stainless hlauyog qhov kev xaiv nrov rau ntau daim ntawv thov, nws yog ib qho tseem ceeb kom nkag siab txog nws cov kev txwv thiab qhov tsis zoo.
Cov khoom yog raug rau pitting thiab crevice corrosion, nrog rau kev sib kis. Nws lub zog siab tuaj yeem ua rau muaj kev lav phib xaub hauv qee yam kev siv, thiab nws qhov kub tsis kam muaj kev txwv.
Los ntawm kev nkag siab txog cov cons, engineers thiab designers tuaj yeem txiav txim siab txog thaum twg thiab qhov twg siv 304 stainless hlau.
