Ib qho yuam kev thiab raug nqi ntau hauv kev ua haujlwm siab -kub alloys yog xaiv cov khoom siv nkaus xwb raws li tus nqi lossis lub koob npe nrov rau "siab-kub" kev ua haujlwm, tsis quav ntsej txog kev tsom xam ntawm cov khoom siv tshuab.
Pain Point: Ntau tus engineers xaiv Inconel 625 rau siab - cov roj kab hluav taws xob los yog cov khoom sib hloov vim nws zoo heev corrosion kuj, tsuas yog pom tias cov kav dej deform los yog tawg hauv load ntawm 650℃. Conversely, siv GH4169 (718) nyob rau hauv muaj zog acid ib puag ncig tsis ua rau ib tug nkim nyiaj siv, raws li nws tus nqi corrosion yuav sai dua 625.
Xaiv txoj cai nickel-raws li seamless alloy tubing yuav tsum muaj qhov sib npaug ntawm cov qauv kev ncaj ncees thiab kev ua haujlwm ruaj khov. Ntawm Gnee Steel, peb muab cov ntaub ntawv -tsav engineering kev txhawb nqa los pab koj daws qhov teeb meem no.
