Dab tsi yog qhov txawv ntawm 410 stainless hlau thiab 316 stainless hlau?
Dab tsi yog qhov txawv ntawm 410 stainless hlau thiab 316 stainless hlau?
410 stainless hlau yog ib tug siab - hardness, muaj zog sib nqus martensitic stainless hlau nrog lub zog siab, haum rau cov kev siv dav dav, tab sis nws cov corrosion kuj tsuas yog nruab nrab, yog li nws tus nqi qis dua . 316 stainless hlau yog tsis yog - hlau nplaum austenitic stainless hlau nrog zoo corrosion kuj (tshwj xeeb tshaj yog zoo heev tiv thaiv chlorides vim muaj cov molybdenum) thiab zoo weldability, ua rau nws zoo tagnrho rau hnyav marine los yog tshuaj ib puag ncig, tab sis nws yog kim dua thiab muaj me ntsis hardness. Kev lag luam tseem ceeb- tawm ntawm ob yog tus nqi piv rau kev ua haujlwm; 410 stainless hlau muab tus nqi zoo dua rau cov nyiaj thaum tsim khoom siab - lub zog muaj zog, thaum 316 stainless hlau muab kev tiv thaiv saum toj kawg nkaus -tier tiv thaiv nyob rau hauv ib puag ncig hnyav.
Cov hlau nplaum puas tuaj yeem nyiam 410 stainless hlau?
410 stainless hlau yog hlau nplaum vim nws yog martensitic stainless hlau, txhais tau tias nws muaj lub cev -centered cubic (ferritic) qauv thiab cov ntsiab lus hlau siab, ua rau nws txaus nyiam rau cov hlau nplaum, tshwj xeeb tshaj yog tom qab kev kho cua sov. Tsis zoo li cov hlau tsis muaj - hlau nplaum austenitic stainless hlau (xws li 304 lossis 316), 400 series stainless hlau, suav nrog 410, muaj cov hlau nplaum sib nqus vim lawv cov hlau- nplua nuj muaj pes tsawg leeg thiab cov qauv siv lead ua.
410 stainless hlau yog ib tug siab -hardness, muaj zog sib nqus martensitic stainless hlau nrog lub zog siab, haum rau cov kev siv dav dav, tab sis nws cov corrosion kuj yog nruab nrab, yog li nws tus nqi qis dua . 316 stainless hlau yog ib qho tsis yog - hlau nplaum austenitic stainless hlau nrog zoo corrosion kuj (tshwj xeeb tshaj yog tiv thaiv chlorides vim nws cov ntsiab lus molybdenum zoo) weldability, ua rau nws zoo tagnrho rau hnyav marine los yog tshuaj ib puag ncig, tab sis nws yog kim dua thiab me ntsis nyuaj. Kev lag luam tseem ceeb- tawm ntawm ob yog tus nqi piv rau kev ua haujlwm; 410 stainless hlau muab tus nqi zoo dua rau cov nyiaj thaum tsim khoom siab - lub zog muaj zog, thaum 316 stainless hlau muab kev tiv thaiv saum toj kawg nkaus -tier tiv thaiv nyob rau hauv ib puag ncig hnyav.
UNS S316000 yog austenitic stainless hlau nrog cov ntsiab lus molybdenum ntawm 2-3% thiab cov ntsiab lus chromium siab dua 410 stainless hlau, feem ntau 16-18%. Yog li ntawd, nws muaj kev tiv thaiv corrosion zoo dua li 410 stainless hlau hauv feem ntau ib puag ncig. Tsis tas li ntawd, 316 stainless hlau yog kub-resistant dua 410 stainless hlau thiab tsis tshua muaj kev cuam tshuam rau tej yam tshuaj. Qhov tsis zoo yog tias, vim nws cov ntsiab lus chromium thiab molybdenum siab dua, 316 stainless hlau tseem kim dua 410 stainless hlau.
