309S stainless hlau yog cov hlau tsis muaj hlau uas muaj cov hlau tsis zoo uas muaj kev kub ntxhov thiab kev tiv thaiv corrosion.
Cov hauv qab no yog cov yam ntxwv tseem ceeb ntawm 309S stainless hlau:
1. Kub kub tsis kam: 309S stainless hlau muaj qhov kub thiab txias tsis kam thiab tuaj yeem siv tau ntev ntawm qhov kub txog li 1000 degree. Nws yog qhov tsim nyog rau cov cuab yeej siv thiab qhov cub hauv qhov kub thiab txias.
2. Corrosion kuj: 309S stainless hlau muaj corrosion kuj zoo nyob rau hauv corrosive media xws li acids, alkalis, thiab ntsev, tshwj xeeb tshaj yog tawm tsam muaj zog acids xws li sulfuric acid thiab nitric acid.
3. Anti-oxidation kev ua tau zoo: 309S Stainless Stainless muaj cov khoom chromium siab, uas tuaj yeem tsim cov hlau saum npoo av los ntawm ua oxidized thiab nthuav nws lub neej kev pabcuam.
4. Kev ua tau zoo: 309S stainless hlau muaj cov yas zoo thiab weldability, thiab tuaj yeem tsim thiab ua tiav los ntawm kev ua haujlwm txias, ua haujlwm kub, thiab lwm yam.
5. Lub zog thiab hardness: 309S stainless hlau muaj lub zog siab thiab hardness, thiab tuaj yeem muab cov khoom siv zoo dua qub thiab hnav tsis kam hauv qee qhov chaw tshwj xeeb.
Feem ntau, 309S stainless hlau yog ib tug multifunctional high-alloy stainless hlau haum rau ntau yam kev lag luam teb nyob rau hauv high kub thiab corrosive ib puag ncig, xws li tshuaj lom neeg kev lag luam, roj av, hluav taws xob fais fab, thiab lwm yam. 309S stainless hlau muaj cov nram qab no zoo heev tshav kub tsis kam thiab corrosion kuj. :
1. Qhov kub thiab txias tsis kam: 309S stainless hlau tuaj yeem siv rau hauv qhov kub thiab txias ib puag ncig ntev, thiab nws cov cua kub tsis kam tuaj yeem ncav cuag ntau tshaj 1000 degree. Nws muaj cov thermal expansion coefficient tsawg thiab zoo thermal conductivity, thiab tuaj yeem tswj cov qauv kev ruaj ntseg thiab txhua yam muaj zog ntawm qhov kub thiab txias.
2. Tiv thaiv kev ua yeeb yam: lub roj chromium hauv 309s stomium steel tuaj yeem hnov mob oxygen nyob rau hauv cov huab cua los ua ib qho kev tiv thaiv hlau, uas tiv thaiv cov hlau saum npoo ntawm ua oxidized. Cov txheej txheej chromium oxide no tuaj yeem muab cov khoom tiv thaiv oxidation zoo, muab 309S stainless hlau ua lub neej zoo los tiv thaiv oxidation hauv qhov kub thiab txias.
3. Corrosion kuj: 309S stainless hlau muaj corrosion kuj zoo rau qee yam corrosive media xws li acids, alkalis, thiab ntsev. Tshwj xeeb tshaj yog nyob rau hauv high-kub acidic ib puag ncig, xws li sulfuric acid, nitric acid thiab lwm yam muaj zog acid media, 309S stainless hlau qhia zoo heev corrosion kuj.
4. Oxidation-txo tsis kam: 309S stainless hlau muaj qhov zoo oxidation-txo tsis kam thiab tuaj yeem ua haujlwm ruaj khov hauv oxidation thiab txo qhov chaw. Qhov no tso cai rau 309S stainless hlau tseem muaj kev tiv thaiv corrosion zoo nyob rau hauv qee qhov kev ua haujlwm tshwj xeeb, xws li txo cov cua sov ntawm qhov kub thiab txias.
Piv txwv li, 309S stainless hlau yog dav siv nyob rau hauv high kub thiab corrosive ib puag ncig vim nws zoo heev kub kuj thiab corrosion kuj. 309S stainless hlau muaj corrosion kuj zoo nyob rau hauv cov nram qab no corrosive media:
1. Acid media: 309S stainless hlau muaj corrosion kuj zoo rau qee cov kua qaub, xws li sulfuric acid, nitric acid, hydrochloric acid, thiab lwm yam. Nws tuaj yeem tiv taus qhov yaig ntawm cov acids uas muaj zog thiab muaj kev tiv thaiv corrosion zoo.
2. Alkaline xov xwm: 309S stainless hlau kuj muaj qhov zoo corrosion kuj rau qee qhov alkaline xov xwm, xws li sodium hydroxide, potassium hydroxide, thiab lwm yam. Nws tuaj yeem tiv taus qhov yaig ntawm cov alkaline xov xwm no thiab tuav ruaj khov corrosion.
3. Chloride nruab nrab: 309S stainless hlau kuj qhia tau zoo corrosion kuj nyob rau hauv ib puag ncig uas muaj chloride. Nws tuaj yeem tiv taus qhov yaig ntawm qhov chaw hlau los ntawm cov tshuaj chloride ions thiab txo cov kev cuam tshuam ntawm intergranular thiab kev ntxhov siab corrosion los ntawm chloride ions.
4. Oxidizing media: 309S stainless hlau kuj muaj corrosion kuj zoo nyob rau hauv ib co oxidizing xov xwm. Nws tuaj yeem tiv taus oxidative yaig ntawm cov hlau qhov chaw los ntawm cov oxidizing xov xwm thiab tuav zoo corrosion kuj.
Nws yuav tsum tau muab sau tseg tias txawm hais tias 309S stainless hlau muaj corrosion kuj zoo nyob rau hauv cov xov xwm saum toj no, corrosion kuj tseem tshwm sim nyob rau hauv tej yam huab cua. Yog li ntawd, hauv cov ntawv thov tshwj xeeb, nws tseem yuav tsum xaiv cov khoom tsim nyog thiab tswj cov txheej txheem raws li qhov xwm txheej tiag tiag.
