A572-50 steel i beam yog dav siv hauv kev tsim kho & kev siv lub tsev rau nws tuaj yeem muab lub zog ntau dua rau ib chav tsev ntawm qhov hnyav. Nws cov ntsiab lus tsawg ntawm cov ntsiab lus alloy xws li columbium & vanadium optimize cov khoom hauv lub zog thiab atmospheric corrosion. Ua tsaug rau nws lub zog siab ntawm 50,000 ksi yield zog, A572-50 steel I ntu tau nce ntxiv hloov cov pa roj carbon steel zoo li A36 uas yuav tsum tau tuab dua kom ua tau raws li qhov yuav tsum tau muaj zog.
ASTM 572 Steel I seem muaj nyob rau hauv lwm qib xws li 42, 55 & 60. Thov nrhiav cov tshuaj tshwj xeeb hauv cov lus hauv qab no.
