18MnMoNbR Boiler phaj
18MnMoNbR boiler phaj yog tshwj xeeb steel phaj dav siv nyob rau hauv thermal fais fab nroj tsuag, nuclear fais fab nroj tsuag thiab lwm yam teb. Nws muaj cov khoom siv zoo heev, kev tiv thaiv corrosion thiab kub tsis kam, thiab tuaj yeem tiv taus qhov kub thiab txias ua haujlwm ib puag ncig, yog li nws yog dav siv hauv kev tsim cov boilers, siab hlab ntsha thiab lwm yam khoom siv.
Cov tshuaj muaj pes tsawg leeg ntawm 18MnMoNbR boiler zoo phaj feem ntau suav nrog cov ntsiab lus xws li carbon, silicon, manganese, molybdenum, niobium thiab chromium. Cov ntsiab lus C yog siab dua, yog li nws muaj zog dua thiab toughness. Nyob rau tib lub sijhawm, cov hlau phaj kuj muaj kev tiv thaiv corrosion zoo heev thiab kub tsis kam, tuaj yeem tiv thaiv kev yaig ntawm corrosive media xws li hydrogen sulfide thiab chloride, thiab tsim nyog rau kev tsim khoom siv ua haujlwm hnyav.
Thaum lub sij hawm tsim cov txheej txheem, 18MnMoNbR pvq steel phaj yuav tsum nruj kev kho cua sov thiab ua cov txheej txheem tswj kom nws cov khoom siv thiab corrosion kuj. Nyob rau tib lub sijhawm, lub phaj steel kuj muaj kev ua haujlwm zoo vuam thiab tuaj yeem ua tau raws li qhov yuav tsum tau muaj ntawm ntau yam txheej txheem vuam.
