P275N P275NH boiler hlau phaj
Pressure Vessel Quality Steel Product Description
P275N boiler zoo phaj thiab P275NH siab nkoj phaj khoom yog European txheem tshwj xeeb steel daim hlau rau boilers thiab siab hlab ntsha. Kev siv cov qauv ntawm P275N boiler steel thiab P275NH siab nkoj steel phaj yog EN10028 tshwj xeeb kev mob.
Cov tshuaj muaj pes tsawg leeg ntawm P275N nkoj phaj thiab P275NH siab lub nkoj phaj muaj cov pa roj carbon ntau dua, ua rau lawv muaj zog dua thiab tawv. Nyob rau tib lub sijhawm, nws kuj tseem nplua nuj nyob rau hauv cov ntsiab lus alloying, xws li manganese, silicon, phosphorus, thiab lwm yam. Cov ntsiab lus no tuaj yeem kho cov nplej thaum lub sij hawm solidification txheej txheem ntawm steel thiab txhim kho lub zog thiab toughness ntawm cov hlau. Tsis tas li ntawd, qhov tsim nyog ntawm nitrogen ntxiv rau P275N boiler phaj thiab P275NH boiler phaj hlau los txhim kho lawv cov hardness thiab corrosion kuj.
P275N siab hlab ntsha hlau thiab P275NH boiler steel phaj tsis tsuas yog muaj lub zog siab, tab sis kuj muaj qee yam kev ua haujlwm zoo xws li toughness, qaug zog tsis kam, cuam tshuam tsis kam, corrosion kuj, vuam thiab ua haujlwm yooj yim. Nws yog feem ntau siv nyob rau hauv lub lauj kaub thiab siab hlab ntsha manufacturing kev lag luam, xws li boiler khoom, siab hlab ntsha, reactors, reactors, spherical tso tsheb hlau luam, siab pipelines, petrochemical khoom, tshuaj, khoom siv roj av, thiab lwm yam.
