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?
Stainless hlau 410 - yog ib qho nyuaj heev, sib nqus martensitic stainless hlau nrog lub zog siab, haum rau kev siv dav, tab sis nws cov corrosion kuj yog qhov nruab nrab, yog li nws qis dua. Stainless hlau 316 - yog cov hlau tsis muaj hlau nplaum austenitic stainless hlau nrog zoo corrosion kuj (tshwj xeeb tshaj yog rau chlorides vim muaj molybdenum) thiab weldability zoo, ua rau nws zoo tagnrho rau hnyav marine thiab tshuaj ib puag ncig, tab sis nws yog kim dua thiab muaj zog dua me ntsis. Lub ntsiab kev lag luam tawm ntawm ob - yog tus nqi / kev ua tau zoo: 410 stainless hlau muab cov txiaj ntsig zoo tshaj plaws rau cov nyiaj thaum tsim cov khoom siv muaj zog, thaum 316 stainless hlau muab kev tiv thaiv zoo tshaj hauv cov cheeb tsam hnyav.
Cov hlau nplaum puas tuaj yeem nyiam 410 stainless hlau?
410 stainless hlau yog hlau nplaum vim nws yog martensitic stainless hlau, lub ntsiab lus nws muaj ib tug ntim-centered cubic (ferritic) qauv thiab cov ntsiab lus hlau siab, uas ua rau nws magnetically txaus nyiam, tshwj xeeb tshaj yog tom qab kev kho cua sov thiab hardening. Tsis zoo li cov hlau tsis sib nqus austenitic stainless hlau (xws li 304 lossis 316), 400 series stainless hlau, suav nrog 410, muaj lawv tus kheej hlau nplaum vim lawv cov hlau nplua nuj muaj pes tsawg leeg thiab crystalline qauv.
Stainless hlau 410 - yog ib qho nyuaj, muaj zog sib nqus martensitic stainless hlau nrog lub zog siab, haum rau kev siv dav, tab sis muaj qhov nruab nrab corrosion kuj, uas piav qhia nws tus nqi qis dua. Stainless hlau 316 - yog cov hlau tsis muaj hlau nplaum austenitic stainless hlau nrog corrosion kuj zoo heev (tshwj xeeb tshaj yog rau chlorides vim nws cov ntsiab lus molybdenum) thiab weldability zoo, ua rau nws zoo tagnrho rau siv nyob rau hauv hnyav marine los yog tshuaj ib puag ncig, tab sis nws yog kim kim thiab me ntsis nyuaj. Lub ntsiab kev lag luam tawm ntawm ob - yog tus nqi / kev ua tau zoo: 410 stainless hlau muab tus nqi zoo tshaj plaws rau cov nyiaj hauv cov khoom siv muaj zog, thaum 316 stainless hlau muab kev tiv thaiv zoo tshaj plaws hauv cov cheeb tsam 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 corrosion kuj zoo dua 410 stainless hlau nyob rau 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 yog kim dua li 410 stainless hlau.
