a572 gr.55 siab zog steel ntawv cov khoom cov ntsiab lus
A572 Qib 55 steel phaj raws li ASTM A572 tus qauv yog siab - zog, qis- alloy structural steel siv nyob rau hauv kev tsim kho thiab kev siv cov qauv. ASTM A572 Qib 380 steel muaj lub zog tensile ntawm 485MPa (tsawg kawg) thiab qhov tsawg kawg nkaus lub zog ntawm 380Mpa.
A 572 55 siab tensile steel phaj tuaj yeem khoov lossis tsim los ntawm kev ua haujlwm txias, thiab tseem muaj kev tiv thaiv zoo rau atmospheric corrosion, uas muaj txiaj ntsig zoo rau kev ua haujlwm ntawm lub neej ntawm steel qauv. Rau A572 Qib 55 steel daim ntaub ntawv xws li welded choj cov qauv, ntswj toughness yog ib qho tseem ceeb thiab qhov yuav tsum tau ua kom toughness yuav tsum tau sib tham ntawm tus neeg yuav khoom thiab cov chaw tsim khoom.
