Taw qhia rau Atmospheric Corrosion Resistant Steel

Atmospheric corrosion-resistant steel, tseem hu ua huab cua-resistant steel, yog cov hlau tsis tshua muaj hlau ua los ntawm kev ntxiv qee yam ntawm cov ntsiab lus alloying rau cov hlau zoo tib yam. Lub ntsiab alloying Cheebtsam yog Cu, P, Cr, Ni thiab lwm yam.
Cov ntaub ntawv yooj yim
Atmospheric corrosion-resistant steel (xws li huab cua-resistant steel) yog hais txog cov hlau tsis tshua muaj hlau nrog zoo atmospheric corrosion kuj ua los ntawm kev ntxiv ib co nqi ntawm Cu, P, C los yog Ni, Mo, Nb, Ti thiab lwm yam alloying ntsiab rau lub hlau. Nyob rau hauv kev lag luam thiab nyob deb nroog atmospheric ib puag ncig, weathering steel ua ib tug ntom thiab ruaj khov oxidation tiv thaiv zaj duab xis nyob rau saum npoo ntawm nws substrate, uas thaiv cov nkag ntawm corrosive media thiab muaj zoo heev tiv thaiv atmospheric corrosion. Txawm li cas los xij, cov txheej txheem corrosion ntawm cov pa roj carbon zoo tib yam Cov txheej txheem xeb yog xoob thiab muaj micro-cracks, uas tsis tuaj yeem tiv thaiv lub hauv paus hlau.
