Ss 316 ntawv thiab SS 304 daim ntawv
Qhov sib txawv ntawm SS 316 ntawv thiab SS 304 daim ntawv
Lub ntsiab sib txawv ntawm ss 316 thiab SS 304 stainless hlau daim phiaj yog lawv cov tshuaj lom neeg cov tshuaj lom neeg, thiab cov txiaj ntsig corrosion tsis kam. SS 316 muaj Molybdenum, ib qho kev ua kom nws txoj kev tiv thaiv mus rau chlorides thiab lwm yam tshuaj uas muaj kev thaj yeeb, ua rau nws haum ntau rau kev siv cov chaw hnyav.
Dab tsi yog qhov tsis zoo ntawm 304 stainless hlau?
Thaum 304 stainless hlau yog dav siv rau nws corrosion tsis kam thiab versatility, nws muaj qee qhov tsis zoo. Cov kev sib tw suav nrog kev pitting thiab crevice corrosion hauv chloride hauv chloride hauv chloride hauv chloride hauv chloride hauv chloride {2} Lub zog nplua nuj, thiab muaj peev xwm rau kev ntxhov siab corrosion tawg nyob rau qee yam. Tsis tas li ntawd, nws tsis haum rau siv nyob rau hauv kev kub siab heev lossis muaj kuab acidic.
Tshuaj Muaj Tshuaj
SS 304 lub phaj muaj cov ntsiab lus tsib xee tsawg dua, xws li ntawm 8-10.5% npib tsib xee thiab 18-20% chromium. SS 316 lub phaj, ntawm qhov tod tes, muaj cov ntsiab lus npib tsib xee ntawm 10-14% thiab cov ntsiab lus chromium ntawm 16-18%. Lub siab dua tsib xee cov ntsiab lus nyob rau hauv SS 316 lub phaj muab cov neeg zoo corrosion tsis kam nyob hauv chloride ib puag ncig thiab dej qab zib ib puag ncig piv rau SS 304 phaj.
Qhov sib txawv ntawm ss 316 thiab SS 304 phaj nyob hauv lawv cov tshuaj lom neeg muaj pes tsawg leeg. SS 316 yog ib qho kev siv roj av uas muaj molybdenum, uas ua rau nws ntau dua cov ntsiab lus tseem ceeb, ua rau nws haum rau cov kev siv marine lossis cov khoom siv acidic. Nyob rau hauv cov nqe lus ntawm cov tshuaj muaj kuab lom, lub ntsiab sib txawv yog tias SS304 feem ntau muaj 18% npib tsib, thaum chromium thiab 12-15% npib tsib caug. Tsis tas li ntawd, SS316 muaj 2-3% Molybdenum, uas yog tsis muaj nyob rau hauv SS304.
Corrosion Kuj
SS316 phaj feem ntau ntau dua corrosion - tiv taus ntau dua li SS304 phaj, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig muaj chloride ions. Qhov no yog vim SS316 lub phaj muaj cov ntsiab lus molybdenum siab dua, uas ua rau nws tsis kam rau pitting corrosion. Txawm li cas los xij, SS304 lub phaj tseem ua tau zoo nyob rau hauv ib puag ncig tsawg.
Ob qho tib si 316 Stainless hlau thiab 304 stainless hlau phaj yog tsim ntawm cov hlau hlau, tab sis nrog cov lej sib txawv. SS304 Phaj muaj chromium, npib tsib xee, thiab carbon, thaum cov pa roj carbon, thaum cov pa roj carbon, thaum cov pa roj ss316 muaj molybdenum nrog rau cov ntsiab pom hauv SS304. Lub ntsiab lus ntxiv no muab SS316 ib qho kev tiv thaiv corrosion siab dua li SS304. Rau ntug hiav txwv lossis tsev txwv ib puag ncig, 316 qib stainless hlau yuav tsum tau siv vim nws lub siab corrosion tsis kam - txog 3 zaug uas muaj steel stainless hlau.
