304L yog cov pa roj carbon tsawg (C Tsawg dua lossis sib npaug li 0.03) austenitic stainless hlau, cov khoom siv hlau tsis zoo, thiab ib qho ntawm cov hlau tsis zoo siv feem ntau.
Dab tsi yog cov khoom thiab kev siv ntawm 304L?
Tshuaj muaj pes tsawg leeg: Cov tshuaj muaj pes tsawg leeg ntawm 304L stainless hlau muaj xws li hlau (Fe), chromium (Cr), nickel (Ni), manganese (Mn), silicon (Si), hlau (P), thiab sulfur (S). Ntawm lawv, cov ntsiab lus ntawm chromium yog 18-20 feem pua , thiab cov ntsiab lus ntawm cov lej yog 8-12 feem pua , ob lub ntsiab lus no yog cov ntsiab lus tseem ceeb los txhim kho corrosion ntawm stainless hlau.
1. Cov khoom siv kho tshuab: 304L stainless hlau muaj cov khoom siv zoo heev, nws lub zog tensile ntau dua lossis sib npaug ntawm 520 MPa, lub zog tawm los yog ntau dua lossis sib npaug li 205 MPa, elongation yog ntau dua lossis sib npaug li 40 feem pua, thiab hardness tsawg dua. tshaj los yog sib npaug rau 201 HB.
2. Corrosion kuj: 304L tsis steel muaj corrosion kuj zoo, muaj peev xwm tiv taus corrosion nyob rau hauv feem ntau cov tshuaj. Tshwj xeeb tshaj yog nyob rau hauv ib puag ncig ntawm hydrogen ions, nws cov corrosion kuj txawv dua li 304 stainless hlau.
3. Cov khoom ua haujlwm: 304L stainless hlau muaj machinability zoo thiab weldability, thiab tuaj yeem siv rau ntau yam kev ua thiab vuam ua haujlwm.
4. Daim ntawv thov thaj chaw: Vim304L stainless hlaumuaj kev tiv thaiv corrosion zoo, kev ua tau zoo, thiab kev sib txuas, nws yog dav siv hauv tshuaj lom neeg, roj av, khoom noj khoom haus, tshuaj, marine, thiab lwm yam, tshwj xeeb tshaj yog tsim rau cov chaw uas yuav tsum tau ua haujlwm hauv high-temperature thiab rotten ib puag ncig. Tib lub sijhawm,
304L stainless hlaukuj tseem siv tau rau hauv cov khoom siv hauv tsev, kev tsim kho, thiab kho kom zoo nkauj.
