Inconel 625 thiab 718: Cov ntawv thov kev lag luam
Inconel 625 thiab Inconel 718 tau siv dav hauv kev lag luam tseem ceeb uas yuav tsum tau muaj qhov kub thiab txias, kev kub siab, thiab cov xov xwm corrosive. Ob lub alloys yog tsim nyob rau hauv ntau cov ntaub ntawv xws li sawb, tiaj tus, profiled hlau, thiab round / ca / square hlau, thiab nquag siv nyob rau hauv stamped qhov chaw. Inconel 625 qhov kom zoo dua yog nyob rau hauv nws cov ntsiab lus chromium thiab molybdenum siab dua, ua rau nws zoo tagnrho rau cov tshuaj corrosive thiab marine ib puag ncig. Cov ntawv thov muaj xws li cov kav hlau hloov tau yooj yim, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, cov dej hiav txwv -cov khoom siv corrosive, thiab cov khoom siv roj hauv dej hiav txwv (cov kab rov qab, cov kab hluav taws xob, cov cuab yeej downhole). Nws zoo heev oxidation tsis kam thiab ua yooj yim ua rau nws zoo tagnrho rau ib puag ncig xws li cryogenic mus rau siab - kub gases.
Inconel 718 yog tsim los rau kev txhim kho nag lossis daus- lub zog hnyav thiab yog dav siv nyob rau hauv siab - qhov kub thiab txias - cov kabmob xws li tshuab aerospace, turbomachinery, siab - lub zog fasteners, thiab kev sib tw cav qhov chaw, tshwj xeeb tshaj yog tsim rau cov ntawv thov uas tsis tshua muaj siab creep, thiab yuav tsum muaj roj ntau. siab -kub seem stability.
Aerospace: Inconel 718 yog cov khoom tseem ceeb rau siab - cov khoom kub thiab cov qauv bolts hauv cov roj turbines; Inconel 625 yog siv nyob rau hauv cov pa system, piping, thiab engine peripheral Cheebtsam uas tsis tshua muaj corrosion yuav tsum tau.
