CortenA CortenB atmospheric steel phaj
Atmospheric Corrosion Steel Phaj Khoom Description
CortenA weathering steel phaj, tseem hu ua COR-TEN A lossis Weathering Steel A.
CortenA corrosion-resistant steel phaj yog paub txog nws zoo corrosion kuj, tshwj xeeb tshaj yog haum rau sab nraum zoov siv, thiab muaj peev xwm tsim ib tug ruaj khov xeb txheej tsis muaj painting.
CortenB weathering steel phaj muaj me me ntawm cov hlau alloy xws li tooj liab, npib tsib xee, chromium, thiab phosphorus. Cov ntsiab lus no ua haujlwm ua ke los tsim cov yeeb yaj kiab oxide ntom oxide zaj duab xis nyob rau saum npoo ntawm cov hlau, siv tau qeeb qeeb hauv kev xeb ntxiv corrosion.
