Q550NH huab cua phaj
Corten Steel Cov Khoom Siv Khoom Piav Qhia
Q550NH atmospheric corrosion resistant steel yog cov huab cua steel tsim los tiv thaiv atmospheric corrosion thiab muaj zog thiab zoo toughness. Nws yog siv nyob rau hauv ntau yam kev siv xws li txuas hniav, vaj tse, thiab lwm yam qauv raug rau huab cua hnyav.
Q550NH weathering steel muaj alloying ntsiab xws li tooj liab, npib tsib xee, chromium, thiab phosphorus, uas pab txhim kho nws corrosion kuj. Lub xub ntiag ntawm cov ntsiab lus no tsim cov txheej txheem tiv thaiv ntawm cov hlau thaum raug rau cov cua, uas yuav pab tiv thaiv corrosion ntxiv.
Q550NH atmospheric steel muaj qhov tsawg kawg nkaus lub zog ntawm 550 MPa thiab lub zog tensile yam tsawg kawg nkaus ntawm 620 MPa, ua rau nws muaj zog thiab ruaj khov khoom siv rau cov qauv siv. Nws feem ntau yog muab rau hauv lub xeev normalized lossis tswj tau dov, uas txhim kho nws cov tawv nqaij thiab ductility.
Ntxiv rau nws siv hauv kev siv cov qauv, Q550NH corten hlau ntawv kuj tseem siv rau hauv kev tsim cov thawv, railway dov Tshuag, thiab lwm yam khoom siv sab nraum zoov uas yuav tsum tau muaj zog thiab zoo corrosion kuj.
