316 Stainless Steel Yeeb Nkab - Kev Lag Luam Kev Siv Tshuaj thiab Kev Tiv Thaiv corrosion

Q1: Cov tshuaj lom neeg twg tuaj yeem 316 stainless hlau yeeb nkab tiv taus? A1: Nws tuaj yeem tiv taus cov kua qaub feem ntau (xws li dilute sulfuric acid, nitric acid), alkalis, ntsev thiab lwm yam tshuaj lom neeg, tshwj xeeb tshaj yog muaj zog tiv thaiv chloride corrosion, uas yog tsim rau cov khoom siv tshuaj lom neeg nrog cov xov xwm nyuaj.

Q2: 316 stainless hlau yeeb nkab puas tuaj yeem siv los thauj cov concentrated sulfuric acid? A2: Nws nyob ntawm qhov concentration thiab kub. Rau qis-kev sib xyaw thiab qis- kub concentrated sulfuric acid, nws tuaj yeem siv tau; tab sis rau siab -concentration thiab siab- kub concentrated sulfuric acid, nws tsis haum, vim nws yuav corrode nto ntawm stainless hlau.

Q3: Dab tsi yog qhov yuav tsum tau vuam ntawm 316 stainless hlau yeeb nkab hauv kev lag luam tshuaj? A3: Vuam yuav tsum siv qhov sib txuam 316 lossis 316L vuam rods, tswj qhov vuam kub thiab ceev, tsis txhob vuam tsis xws luag, thiab ua tom qab- vuam annealing yog tias tsim nyog los xyuas kom meej qhov corrosion kuj thiab lub zog ntawm cov vuam sib txuas.

Q4: Lub neej ua haujlwm ntev npaum li cas ntawm 316 stainless hlau yeeb nkab nyob rau hauv ib puag ncig tshuaj? A4: Raws li kev siv ib txwm muaj thiab kev saib xyuas kom zoo, nws lub neej kev pab cuam tuaj yeem ncav cuag ntau tshaj 20 xyoo, uas ntev tshaj li ntawm 201 thiab 304 stainless hlau kav hauv cov cheeb tsam tshuaj.

Q5: Dab tsi yog qhov txawv ntawm 316 thiab 316Ti stainless hlau kav? A5: 316Ti ntxiv titanium (Ti) lub caij, uas muaj qhov zoo ntawm qhov kub thiab txias tsis kam thiab intergranular corrosion kuj, thiab yog qhov tsim nyog rau siab - cov khoom siv tshuaj kub thiab tuab - cov khoom siv phab ntsa.
