Dab tsi yog qhov txawv ntawm 316L thiab 316ti stainless hlau kav?
Tso lus
316Ti stainless hlau yeeb nkab, tus thawj British steel qib yog 320S31, uas yog cov txheej txheem carbon 316 stainless hlau nrog titanium stability. Thaum rhuab hauv 425-815 degree ntau, qhov sib ntxiv ntawm titanium tuaj yeem txo qhov kev pheej hmoo ntawm intergranular corrosion ntawm stainless hlau cov ntaub ntawv.
1. Cov yam ntxwv ntawm 316Ti
316Ti yog titanium-stabilized 316 stainless hlau uas nws cov tshuaj tseem ceeb xws li chromium (Cr), npib tsib xee (Ni), molybdenum (Mo) thiab titanium (Ti). Cov khoom no tau txais kev qhuas zoo heev rau nws qhov zoo tshaj plaws corrosion kuj thiab kub lub zog, thiab tshwj xeeb tshaj yog haum rau cov khoom siv thiab cov kav dej hauv kev lag luam tshuaj, marine thiab lwm yam kev lag luam. Qhov sib ntxiv ntawm titanium yog qhov tseem ceeb ntawm 316Ti, uas tuaj yeem kho cov nplej thiab txhim kho kev ua haujlwm thiab tawv ntawm cov hlau tsis muaj steel.
Hais txog lub cev muaj zog, qhov ntom ntawm 316Ti stainless hlau yog li 8. Tsis tas li ntawd, nws muaj qhov zoo thermal thiab hluav taws xob conductivity. Hais txog cov khoom siv kho tshuab, 316Ti nthuav tawm lub zog tensile siab thiab lub zog tawm los thaum tuav cov elongation zoo, uas ua rau nws zoo heev toughness thaum withstand hnyav loads thiab cuam tshuam.
2. Qhov txawv ntawm 316Ti thiab 316L
1. Cov ntsiab lus carbon sib txawv:
Cov ntsiab lus carbon nyob rau hauv 316L stainless hlau yog qis dua, uas txo cov grain ciam corrosion rhiab heev ntawm cov hlau, yog li txhim kho nws corrosion kuj, thiab yog tshwj xeeb tshaj yog haum rau tej corrosive ib puag ncig. Hauv kev sib piv, cov ntsiab lus carbon hauv 316Ti stainless hlau yog me ntsis siab dua, tab sis nws cov kev tiv thaiv corrosion kuj tseem txhim kho vim qhov sib ntxiv ntawm titanium.
Cov nram qab no yog lus Askiv sib piv cov lus ntawm cov tshuaj muaj pes tsawg leeg thiab txhua yam khoom ntawm 316L thiab 316Ti stainless hlau:
